Abstract

The startup, retrain, renegotiation quick connect or other processes of handshaking between communication systems involve the exchange of certain modulation, constellation, precoder, prefilter and other communication related information. The communication systems exchange one long information sequence including all the necessary communication information. Subsequently, the communication systems start transmitting short sequences, including an acknowledgement information portion. If one of the communication systems does not receive an acknowledgement within a predetermined time or event, that communication system may retransmit another long information sequence. After such retransmission, the retransmitting communication system may continue transmitting the long information sequences or may start transmitting the short sequences once again. Eventually, each of the communication systems should receive a long information sequence and acknowledge their receipt of such sequence.

Description

499809 A7 ________________________ B7 V. Description of the Invention (1) Field of the Invention The present invention relates to a communication system. In particular, the invention relates to speeding up the connection time between communication systems. BACKGROUND OF THE INVENTION 56 kbps modems are now standardized in accordance with ITU V · 90 recommendations. However, many 5 kb ps modems, especially end-user terminals, can only be compatible with previous modes such as K 5 6 f 1 e X, V. 3 4, V · FC, and V · 32. These previous modems, as well as down-capable V · 90 modems, had undesirably long connections or initial times between dial-up and full-speed data modes. The startup time can reach 30 seconds, which is quite annoying and unattractive for end users, especially considering other data communication protocols that operate in always-connect mode. V.90 modems that support previous modem protocols typically perform the functions shown in Table 1 during the initial period. The time associated with the operations disclosed in Table 1 will vary with different connections depending on factors such as server speed and channel conditions.

However, many channels can only support previous modes such as @ _ such as V · 3 4. Therefore, although most newer computers (especially those that are sold with new personal computers) are compatible with V · 90 recommendations, many previous models are still in use. Back to the first _ Mo mode V · 9 0 modem-related long initialization time in many applications is irritating and undesired, and for the user to establish a connection after an unexpected disconnection Will be a serious obstacle. In addition, even in the case of a connection between two V.90 modem devices, the long V.90 startup phase will test the patience of impatient end users. Therefore, the height $ is to be reduced by the initialization time typically associated with traditional V.90 modem systems. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A given modem communication activity may be interrupted or disconnected for many reasons. For example, a call waiting signal may interrupt the modem connection so that the modem call must be reconnected or reinitialized. In another embodiment, the current modem connection can be put on standby so that the user can answer the incoming call in response to the call waiting signal or enable the user to broadcast an outgoing call without interrupting the modem connection. Ideally, the computer connection can be rebuilt in an immediate manner. However, in an actual system, a retraining or reinitialization procedure must be performed to ensure that the two-terminal devices are properly synchronized and that the channels are properly equalized. As mentioned above, during this retraining and reinitialization period, the traditional V · 90 modem system must take more than 20 seconds. Therefore, it is also desirable to reduce the reconnection time between the same modem devices in response to a temporary disconnection or temporary interruption in data communication.

Description of the invention (5) During the replacement of information and other parameters ’, one of the main time-consuming parts of modem training and negotiation will occur. Referring to FIG. 5, for example, it shows that the analog pulse code modulation (APC M) modem 5 8 0 during the negotiation of v · 90 will transmit the constellation parameter (CP) frame 5 1 0 to the digital pulse code modulation (d (PS Μ) modem 590, digital pulse code modulation (DP s) modem 590 will transmit modulation parameter (MP) frame 5 2 0 to APC Μ modem 580 during the exchange. As described below, the MP frame 520 and the CP frame 510 are in a synchronous form and contain a lot of information and C R C information bits for error detection purposes (refer to FIGS. 17 and 18). As shown in FIG. 5, the APC M modem 5 8 0 will continuously transmit the CP frame 510 to the DPCM modem 590 until the APCM modem 5 8 0 receives the transmitted CP frame 5 1 from the DPC M modem 5 9 0. Until the receipt of the confirmation. Similarly, the DPC M modem 5 9 0 will continuously transmit the MP frame 5 2 0 to the APC M modem 5 8 0 until the DP CM modem 5 9 0 receives the transmitted CP frame from the AP CM modem 5 8 0. 5 2 0 until receiving confirmation. The reception confirmation for CP frame 5 10 will be transmitted in the form of MP frame 5 2 0, which contains individual and per-bit information and has a confirmation bit set to Μ frame 5 2 0 3 3. MP frame 5 2 0 with confirmation bits 3 3 set to 1, 1 will be represented by MP / frame 5 2 2. Once the DPCM modem 590 receives the CP frame 510, the DPCM modem 590 will start transmitting MP > frame 5 2 instead of MP frame 5 2 0. This repeated transmission of MP / box 5 2 2 will continue until DP CM modem 5 9 0 receives MP or MP / box 5 2 0 or JI .-- 1 ^ ----------- -ί--Order --------- line (please read the notes on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -8- 499809 A7 ---- B7 V.

A CP frame 5 1 0 with a confirmation bit 3 3 set to 1, 1 will be represented by CP / frame 5 1 2. Once the APCM modem 580 receives the MP box 520, the APCM modem 580 will start transmitting CP > Box 5 1 2 instead of CP Box 5 10. This repeated transmission of C P 1 frame 5 1 2 will continue until AP C M modem 5 8 0 receives C P or C P / frame 5 1 0 or 5 1 2 reception confirmation. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. The repeated transmission of the CP, Cp /, MP, and Mρ / boxes containing information bits is actually a considerable consumption. However, as more parameters and information bits have to be exchanged between data modules, this problem becomes more significant in next-generation standards such as the I TU V · 9 2 recommendation. FIG. 19 shows an embodiment of a constellation parameter box of an AP CM modem 5800 called a CP box 1900. As shown, the CP a box contains more information bits than the CP and MP boxes 1 800 and 19 0 0 (see Figures 17, 18, and 19). For example, high-resolution constellation information and Pre-decoder and pre-filter coefficients. The C P a box 1 9 0 0 also contains variable length parameters such as the parameter 1 1 9 2 0, which may add more information bits to the C P a box 1 9 0 0. Because the confirmation mechanism is introduced in ITU Recommendation V · 34 and the confirmation mechanism is reused in ITU Recommendation V · 90, because of these long sequences-9- This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 (Mm) 499809 A7 ____B7 V. Description of the invention (7) Excessively increased the startup time of ITU Recommendation V · 92. For example, during the V · 92 PCM on-chain startup, a significant amount of information needs to be exchanged between the DPCM data machine 590 and the AP PC data machine 580. In particular, the DPCM 590 needs to transmit a long sequence ′, which contains constellation information with high resolution in the CP frame and the precoder and prefilter are received. Therefore, in this technique, there is a strong need to eliminate the huge consumption of repeated transmission of these long sequences containing many parameters and information bits, so as to reduce training and negotiation time and obtain fast connections. SUMMARY OF THE INVENTION The present invention provides a technique for shortening the startup and reconnection time associated with a data communication system using a modem. The fast reconnect technology balances the previously known channel characteristics to reduce the reinitialization time associated with subsequent attempts to reconnect the same two modem devices. According to an illustrative implementation example, the technology of the present invention is used to reduce the reconnection time following communication activities that follow higher-level agreements such as P P P.

Description of the invention (8) The above and other aspects of the invention are implemented in a form. The data transmission system has a first device, and the first device is configured to communicate with the second device on a communication channel. The illustrated method is about establishing communication activities on a communication channel between a first device and a second device, obtaining some operating parameters related to the communication channel for a data transmission system, and storing at least one operating parameter on the second device. After the communication activity is paused, the operating parameters will be called again at the second device. According to an aspect of the present invention, during startup, maintenance, renegotiation, fast connection, or other handshake processing between communication systems, the communication system exchanges some parameters, such as modulation, constellation, precoder, Front filters and other communications related information. The communication system exchanges a long message sequence containing the required parameters or communication information. Then, the communication system starts to send short sequences, including the confirmation information part, but not all other parameters or information embedded in the long sequence. Once each communication system receives a short sequence with a confirmation message representing the receipt of the long message sequence, the communication system may move to the next stage of the handshake process. The use of short information sequences actually shortens the delay and consumption introduced by the handshake process and eliminates the continuous transmission and retransmission of long information sequences. In another aspect of the present invention, if one of the communication systems does not arrive at a predetermined time or event, When the confirmation sequence is received, the communication system can resend another long information sequence. Then, the retransmission communication system can continue to transmit the long information sequence or can start transmitting the short sequence again. These and other aspects of the present invention will be made clearer with further reference to the following counter-illustrations.

The received signal contains information about the characteristics of the communication channel. In particular, the received signal contains information related to the analog local circuit 1 1 2. In the embodiment described here, one of the modem devices will be digitally connected to the digital telephone network 108, and the analog local loop 1 12 will affect the signal in a way that is virtually unchanged from one connection to the other. Although the analog characteristics are similar for repeated connections to the same server modem 102, slight changes in temperature and humidity, other environmental changes, physical changes in system hardware, and other operating parameters can cause For comparison purposes, the current channel characteristics fluctuate randomly. However, the comparison procedure performed during the query work 210 is preferably designed to accommodate these fluctuations. For the sake of explanation, "similar" characteristics mean that the query work 2 10 will assume that the current channel is consistent with a previous channel that has not suffered a general change due to the above-mentioned uncontrollable and unpredictable factors. If the query task 2 1 0 determines that the parameters of the current communication channel do not match the parameters of the previous communication channel, then task 2 1 2 may be performed. Just like job 2 06, job 2 1 2 will prompt the modem system 1 0 to start the conventional initialization routine. In the preferred embodiment, if the modem system 100 confirms that the fast connection protocol is fully supported (query work 204), it is possible to skip most, if not all, of the V8bis program. • Therefore 'Capacity exchange agreement is facilitated by work 2 1 2.

Therefore, "even if the query work 2 1 0 determines that the current channel is not similar to the previous channel" quick start processing 2 0 0 will reduce the overall initialization time of the modem system 1 0 0. If the query task 2 1 0 finds that the channel characteristics of the target "match" the stored characteristics of the previously established channel ', then task 2 1 6 can be performed. During work 2 1 6, a shortened training program is performed. As detailed below, the modem system 100 will balance the known characteristics of the current channel so that the modem device can be trained immediately. For example, 'Although the specific timing stages of digital impairments (for example, captured bit signaling) may be unknown, the pattern of digital impairments will be the same for repeated connections. Therefore, in the case of a V · 90 modem system, it is not necessary to completely perform a lengthy digital impairment learning program.

Description of the invention (28) After 4 0, work 4 0 6 can be performed to initialize a capacity exchange agreement such as V 8 or v 8 bis.

The CR e signal can be used to notify APC Μ, DPC Μ will support the fast connection procedure. CR e The signal can be a modified version of the traditional V · 8 bis tone. For example, the V · 8 bis tone can be AM. Alternatively, the frequency associated with the tone can be pulsated in a periodic manner or a low-level quasi-broadband signal can be added.

Description of Invention (29) Work 4 1 〇 in response to the reception of the QC signal. In cooperation with 4 10, DP c M will send a fast connection confirmation (represented by the QCA signal in Figure 5). As described above with reference to FIG. 2, if the DPCCM does not confirm the QC signal, or if the aPCCM does not know why the QCA signal is not received, then the modem system will perform the conventional startup procedure. As described above with reference to the modem system 300 (refer to FIG. 3), the format, planning, and processing of Q C and Q C A can be performed by individual parts of individual modems. If both DPCM and APCM support fast connection technology, depending on the specific application, any number of initialization routines can be eliminated, modified, or shortened. For example, in the case of a V · 90 compatible modem system, the transmission of the Q C signal inherently indicates that AP MC is in compliance with V · 90. Similarly, the transmission of the Q CA signal can inherently indicate that DPCM is also V.90. As a result, the modem system can be exempt from some or all of the general capability exchange agreements such as V · 8 and / or V · 8 bis. This feature itself can reduce startup lag by 5 seconds (for a typical connection). It should be understood that when DPCCM initially talks to APCM, the above-mentioned quick connection identification and confirmation design related to work 402 to work 4 10 can be equivalently applied. This situation may occur when DPCM calls APCM to establish a communication channel in response to an initial call or request from APCM. In this case, APCM will send a CRe signal, DPPC will send a QC signal, and APCM will send a QC A signal. Different from the above description of the initial call of AP CM, AP CM will transmit the increase signal or sequence that appropriately identifies the conversion sequence signal point to DPC Μ (not embed the signal point in CR e or QCA sequence) Standard (CNS) A4 size (210 X 297 mm) -32 *-

Description of Invention (30) 〇 在After task 4 10, the DP CM performs task 4 1 2 to obtain the signal points for the conversion (or synchronization) sequence. As described above, the Q C signal preferably contains information identifying signal points, and these signal points enable APCM to easily detect the presence of the captured bit signal. As described above with reference to the digital damage learning program 3 64 (refer to FIG. 3), the decision of a specific signal point can be performed by APCM. This decision can be based on past analysis of digital impairments associated with previous connections on the same channel. After the AP C M receives the Q C signal, work 4 1 2 may be performed by the processor 3 1 2. In response to task 4 1 2, task 4 1 4 can be performed so that the appropriate conversion sequence will be transmitted by DPCM. In the illustrated embodiment, the conversion sequence includes the positive and negative values of the signal points obtained in job 4 12. Therefore, DPCM can use the signal points selected by APCM and the appropriate sign (can be determined in advance) to generate a conversion sequence. The conversion sequence is configured and formatted into A P C M, which can synchronize itself with subsequent signals or sequences transmitted by D P C M when detecting the transmission sequence. In this way, the APCM receiver can obtain its timing from the conversion sequence. The conversion sequence can have any predetermined length and have any predetermined sign sequence. For example, in the embodiment shown in FIG. 5, the conversion sequence will be represented by a fast timing sequence (QTS) and a QTS / signal, where QTS represents a specific signal point sequence and QTS \ is the same sequence with opposite sign . In Fig. 5, the Q T S sequence will repeat 810 symbols, and the Q T S \ sequence will repeat 30 symbols.

'As a result, the time of the QTS root sequence and the time of the captured bit signaling (RBS) associated with the network connection do not have a common denominator (other than one). For example, a suitable QTS root sequence is 0, + A, -A, + A, -A (where A represents a signal point that significantly indicates the presence of RBS. Therefore, for the embodiment shown in FIG. 5, This QTS root sequence with a period of five will be repeated 16 times, and the QTS \ sequence contains six repeated root QTS sequences with opposite signs. For the above embodiment, the RBS period will be Assume that the received conversion sequence will accept 30 points of discrete Fourier transform (DFT) to obtain the DPC M timing sequence. In addition, the existence of RBS is revealed at some discrete frequencies related to the DFT results. Method, the timing and RBS information can be selected from the received conversion sequence. In addition, the timing phase information can be obtained independently from the RBS information. The DPC M is preferably configured to transmit a specific signal point sequence during work 4 1 6. Those familiar with modem agreements understand that the signal point sequence can be regarded as a modified answer tone. In Figure 5, this signal point sequence will be represented by the ANS pcm signal.

It is expected that the APC M can detect the conversion sequence once it detects the conversion sequence. This point is required for the signal point sequence. In other words, the detection of the conversion sequence by APC M means that the signal point sequence will follow.

In another embodiment, the number of different ANS pcm signals may be appropriately stored in a look-up table, or the ANS pcm signals may be designed by one of the modem devices and in an appropriate manner before work 4 1 6 Send to another modem device. For example, the ANS pcm signal can be designed to easily detect the presence of RBS by the APC M by analyzing the received ANS pcm signal. In this embodiment, for the conversion sequences (Q T S and Q T S \), R B S may not need to be identified or marked. In the case of V · 8, the response tone is generated with an amplitude modulation of 2 1 〇 〇 Η ζ tone. In contrast, the present invention utilizes the A N S p c m signal to digitally generate a tone using a pulse code to modulate the signal point (for example, a 2100 Hz tone). In other words, the ANSpcm signal is a digital representation of an analog signal. The AN S p cm signal is preferably constituted with a conventional pulse code modulation point, so that the aNS p cm signal can be used for purposes other than a simple answer tone. In the preferred embodiment, the AM Spc signal includes a number of variable pulse code modulation points associated with a particular telephone network. This aspect of the A N S p c m signal is required so that the A M S p c m number can be used to determine or identify the characteristics of the current communication channel ', especially the digital display. The use of a large number of possible codewords will ensure that this paper size applies to the Chinese National Standard (CNS) A4 (21〇x 297 mm) -35- —ί--Γ ------------ r- --Order --------- line (please read the note on the back? Matters before filling out this page) Printed by the Employee Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy Description of the Invention (33) ANS pcm § The number will detect a digital line that may combine two input levels into one output level. The A NS signal is also configured to provide a tone suitable for establishing a network echo canceller and deactivating the network echo suppressor. If a look-up table is used to define the A N S p cm signal, actual implementation is difficult in situations where multiple transmission levels are desired or required. For example, ITU-T Recommendation V · 90 allows DPCM to specify 32 different transmission levels. Storing separate tables for each transmission level may cause excessive memory requirements. Therefore, in another embodiment, a procedure may be defined to map a plurality of codewords related to one transmission level to a corresponding plurality of codewords related to other transmission levels. For example, in the case of defining a PCM codeword table of ANSpcm signals at -0.5 dBm 0 level, the program is about mapping each individual PC M codeword to its corresponding PC M level, according to the required The transmission level is reduced to quantify the level scale, quantize the resulting level back to the nearest PC M level, and convert it into a corresponding PC M codeword. Therefore, the same mechanism can be used in the DPCM transmitter and the APCM receiver to form the corresponding ANSPcm signal, so the same PCM codeword sequence is generated on each side. Note that according to this embodiment, the quantization rule should be accurate when processing the "tie" in quantization, that is, if the two PCM levels are equidistant from the scaled level. For example, this rule means that in the case of a tie, the PCM level closer to zero is chosen. According to yet another embodiment, the entire method of defining the AN Spcm signal should be based on a predetermined deduction method that generates a PCM codeword sequence representative of the ANSp signal. For example, the signal can be defined as 2 1 0 0 Η ζ is Γ ------------ r --- order --------- line (please read the back Note: Please fill in this page again.)

Description of Invention (34) Strongest A set of tones in which the tones are pre-defined in amplitude and initial phase. Then, 'accurate quantization rule in the case of a tie again' is used to quantify the resulting signal based on the closest PCM level. However, this method will also use the sine or cosine function, and accumulate accurate definitions such as fewer bits when the pitch is combined to ensure that the calculation is performed in a consistent manner at both ends so that the ANS pcm signal can be properly detected . As mentioned above, AP CM expects the transmission of the ANS p cm signal. The digital impairments and analog characteristics associated with communication channels affect the ANS p cm signal when the A N S p cm signal is transmitted from the DP CM to the AP CM. Tasks 4 1 8 may be performed by the AP CM to obtain the received sequence related to the AN Sp cm signal point sequence. APCM may then perform work 420 to compare some of the attributes of the received sequence with some of the stored attributes of the previously received sequence associated with the previously established communication channel. In the illustrated embodiment, a previously received sequence coefficient bit impairment learning (D I L) sequence is tethered to the search sequence. In this regard, work 4 2 0 will determine whether the characteristics of the current channel are similar to those of the previously established channel. In the preferred embodiment, the channel characteristics compared in operation 420 are related to the digital impairments in the channel. In other words, working 4 2 0 will damage the channel profile with the stored digital and confirm the current digital damaged channel profile. With the appropriate APCM processor elements, work 420 is performed (see Figure 3). During work 4 2 0, any measurable characteristic of the point / level, any measurable characteristic of the entire received sequence, and / or any measurable signal or quantity related to the point / level can be determined by APC Μ analysis. For example, 'any number of individual points or levels included in the received sequence can be stored in this paper with the Chinese National Standard (CNS) A4 specification (210 > < 297 mm) _ 37 _!! _ ___ l ·! 丨 Order _________ line · (Please read the notes on the back before filling this page) 499809 A7 ----- B7 V. Description of the invention (35) (Please read the phonetic on the back? Matters before filling in this Page) AP c Μ corresponding point or level is compared (the stored point or level can be related to the previous DIL procedure). If the received points / levels are "consistent" with the stored points / levels, or if the difference between the received and stored points / levels is within a threshold, then APC M can assume The current channel attributes correspond to the stored channel attributes (see query work 2 10 in Figure 2). APCM may execute the procedure 421 to appropriately obtain and store some attributes or characteristics of the channel previously established for the current channel. As described above, the program 421 will cause APCM to store the characteristics of the points / levels contained in the received D I L sequence. These past encounters are then used during work 420. In this regard, for example, in response to a subsequent D I L procedure related to the current connection, after completing the comparison at work 4 2 0, the procedure 4 2 1 will update the old D 2 with the new D I L 2. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs As described with reference to Figure 2, if work 4 2 0 determines that the channel characteristics are not adequately matched, the modem system will return to the traditional V · 90 start-up procedure. Figure 5 shows the APCM falling back to the V · 8 protocol and transmitting the traditional V · 8 call menu (CM) message to the DPCM. Then, the traditional V.8 startup for AP CM will run the sequence 502. In response to the CM message, the DPCM generates a traditional V · 8 combined menu (JM) message and initializes it according to the traditional V · 8 (indicated by the sequence 504). For the sake of illustration, the quick start process 4 0 will assume work 4 2 0 to determine that the current communication channel is similar to the previously established communication channel. If APC M confirms the current channel characteristics with the previous channel, it will trigger a quick-start routine to further reduce the number of modem-related systems. -38- This paper standard applies to China National Standard (CNS) A4 (210 X 297) (Centi) 499809 Α7 ------ Β7 V. Description of the invention (36) (Please read the precautions on the back before filling this page) Initialization time. Alternatively, DPCM can be configured to trigger a fast start routine. Therefore, during the initial training of the modem system, work 4 2 2 can be performed. (For the sake of brevity, the part of work 422 and the subsequent work can be performed by APCM and DPCM; the quick start process 4 00 illustrates the combined function in a single process work situation). Task 4 2 2 will cause the AP CM and DP CM to initialize in response to some storage parameters related to the previously established communication channel. As described above, the stored parameters are related to the initialization or training of the equalizer, echo canceller, transmission power level, initial signal point constellation, and so on. Task 4 2 2 can be operated in conjunction with program 4 2 1 and is preferably used to obtain and store initialization parameters related to previous connections. In this regard, the procedure 421 may be appropriately designed to periodically store these parameters during the general data mode of the previous connection after a renegotiation process or in response to any conditions or events related to previous communication activities. Program 4 2 1 can also be configured so as not to accidentally store incorrect settings or initialize parameters. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In a typical V · 90 connection, work 4 2 2 is related to the two-point training phase. Using the previous parameters, the modem system can skip or shorten the traditional V.90 stage 2 exploration and ranging procedures and skip or shorten the traditional V.90 stage 3 digital impairment learning and initial training procedures. As shown in Fig. 5, both AP CM and DP CM can transmit training sequences (represented by T R N 1 signal) during work 4 2 2. These training signals can be used to properly adjust equalizer and echo canceler filter taps and facilitate training of the modem system. Therefore, it is possible to perform one of the most time-consuming procedures initiated by V · 90 in an efficient manner with sufficient time for fine-tuning and training (APC M, etc. -39- This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 (Mm) 499809 A7 ___ B7 V. Description of the invention (37) Training of chemistries). (Please read the note on the back? Matters before filling out this page) In addition to the initial training that occurred during work 4 2 2, work 4 2 4 will also be performed. During work 4 2 4 the data system will perform error correction and / or data compression protocols. In the traditional V · 90 data machine system, the error correction follows the V · 4 2 recommendation, and the data compression follows the V · 42 b i s recommendation. For example, in the general V · 90 operating mode associated with a PPP connection, the V · 42 and V · 42b i s procedures are executed after the last training and before the CH A P / PAP identification procedure. Because CHAP / PAP procedures are more suitable for "error-free" channels, V.42 and V · 42 2 b i s are executed before CPAH / PPP procedures. Unlike traditional V · 90 systems, work 4 2 4 will be executed during Phase 3 of V · 90 startup V · 42b i s ° V · 42b i s moves forward during startup processing to help reduce connection time. In Figure 5, the X ID signal represents a modified version of the traditional V · 4 2 X ID signal. For example, the X ID signal is printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. A subset of the X ID parameters used to negotiate compression and so on can be used. It is also possible to combine the different correction signal sequences shown in Fig. 5 to execute part of the V. 4 2 b i s procedure. For example, the C P t signal represents a conventional V 9 0 C P t signal combined with one or more V · 4 2 b i s signals. In the preferred embodiment, the V.4.2bis program is executed to provide an actual "error-free" channel. After working 4 2 4

In response to the CONN N E C T message, the host software starts the "simultaneous" upper-layer protocol login process, for example, the CHAP or P A P process (work 428). Task 428 may be initialized automatically by the main software or automatically in response to a user login. CHAP / PAP data transmission will be processed in conjunction with the final training. In a preferred embodiment, APCM and DPCM will transmit CHAP / PAP identification data as scrambled digital data on the communication channel. The scrambling of forensics allows the modem device to perform final training on the forensics. In a traditional V · 90 modem system, the final training signal is formatted as a scrambled signal. The scrambled signal contains no information; the last training signal serves only as a white source on the spectrum. When the modem device completes the training process, the present invention balances the last training signal to carry user data. Although C H A P / P A P data is a preferred form of user data, the invention is not limited to the transmission or exchange of authentication data. In addition, the specific scrambling deduction method will vary from application to application. In Figure 5, the dual function signal is represented by T R N 2 A / P P P. In this regard, the receiver areas in the modem device can be trained at the initial data rate during the first time period (for example, during data phase one) so that they can be trained at subsequent time periods (for example, During data phase two), seamlessly transitions to operate at the final data rate. In addition, the P P P login procedure is performed at the initial data rate during the first time, rather than after the modem system has been fully initialized. During the initial data rate time, work can be performed to enable AP CM and DP CM to exchange constellation parameters and adjust in a proper manner.

Work can be performed in the traditional ν · 9 0 manner, 430. These parameters can be used by the modem device during the subsequent data mode. After completing the training and identification procedures, the system preferably transitions to the full data rate in a seamless manner.

Invention Description (41) The modem system can be configured to use the stored analog and digital damage information , Equalizer settings, power levels, echo canceller settings, constellations, etc., nor does it perform time-consuming reconnection or retraining procedures. If the channel connection is interrupted by a call insertion procedure, a pick-up microphone condition at the tapped telephone device, a caller ID request, or any channel damage event, whether the event is planned or unintentional, this stored information Can be used to reset modem parameters immediately. In this case, the customer modem and server modem can store related system attributes, modem operating parameters, channel characteristics, and / or network characteristics. In a practical embodiment, in response to a phone call, the customer data opportunity notifies the server to enter standby mode. The server modem then switches to F S K mode to detect level 2 caller ID information when the server is idle. If the user wants to answer the second call, the customer data machine will periodically send a standby signal or heartbeat to the server to designate the server to continue standby. When the second call ends and the user wishes to start a data call, the customer modem will begin a quick reconnection handshake agreement (described below). On the other hand, if the user wants to terminate the first call, he can send a call break (or, it can end the periodic standby signal). As described with reference to the previous brief description of the channel parameters 3 4 2 and 3 8 2, the fast reconnection handshake will cause the modem device to call the standby channel's storage parameters and attributes and the storage operation parameters related to the receipt device. With this technology, the modem system can be reconnected in seconds. As a result, data mode users will not suffer from lengthy reconnections after processing incoming call spots or caller ID signals.

With this feature, it can be connected in the traditional P p P mode, and the analog r is always connected "mode. For example, 'for a given connection between a client modem and a server modem, the relevant channel compensation information is stored periodically. The customer user can answer the incoming second line call and pause the data mode at the same time as described above. In addition, if the customer user initiates an outgoing voice call, the data mode can be gently terminated. When the voice call is terminated, the customer modem can redial or re-contact the server modem and use the stored parameters to establish a quick connection. Fig. 7 is a flowchart showing a part of the fast connection processing 700 performed by the two modem devices, and Fig. 6 is a timing chart 600, corresponding to the fast reconnection processing performed by the second modem device illustrated. The timing diagram 6 0 0 contains the prefixes and abbreviations commonly used in the case of traditional data communication protocols.

However, the present invention can be used in any suitable situation, and the specific signals, number of sequences, sequence timing, data rate, and interaction between the two modem devices shown in FIG. 6 are not intended to limit the scope of the invention. After the modem system establishes communication activities, and typically after the modem system enters the full-speed data mode, the modem system will perform fast reconnection processing 7 0 0. For the sake of illustration, it can be assumed that the modem system is configured as described above (or is configured in an appropriate manner to support different processing tasks that are not described). It can be assumed that the processing device of the 700 bis modem is compatible with the fast reconnection technique described herein.

Description of the Invention (43) Any confirmation or communication shall be made to determine a quick reconnection Whether the program will be executed. Although fast reconnection is not required to process 700, the modem system can be initialized according to the above-mentioned fast start technology. Therefore, processing 7000 will assume that both modem devices store any number of appropriate channel characteristics, receiver parameters, and other information related to the initialization, training, and synchronization of the modem system. As mentioned above, this information can be stored appropriately during the startup process or periodically and appropriately during the appropriate data mode. Processing 7 0 0 can be used to enable the current modem connection to be quickly reestablished after the modem mode is suspended or any interruption event. In this case, the actual system can maintain a communication link or connection between modem devices. , And allows the user of the customer modem device to suspend the modem connection (or modem data communication mode). During the temporary waiting period, when the client-side modem device is idle, the user can answer another incoming call in response to a call insertion signal, initiate a new outgoing call, and so on. The fast reconnection process 7 0 0 may begin at work 7 2 2. During this period, the DP CM (for example, the modem 3 2 2 shown in FIG. 3) receives the reconnection indication. A reconnect flag can be generated in response to a request to suspend a modem communication activity (for example, a user-initiated request). For example, APCM (for example, modem 304) may generate an appropriate reconnection signal in response to a microphone flash initiated by a user of APCM or in response to a command generated by an application software associated with APCM. Alternatively, the AP CM or data access configuration (DAA) associated with the AP CM may generate a reconnect signal in response to a change in current related to the pickup state of the telephone handset. The in-process detection technology used in this bureau is applicable to the Chinese paper standard (CNS) A4 (210 X 297 mm) for this paper. -46 · ifrlrh! —— ^ — 0 ---- l · —— Order --------- Line _ (Please read the precautions on the back before filling out this page) 499809 A7 ___ ____ B7 V. Description of Invention (44) It is familiar to the person. The reconnect flag will inform the DPCM that the user wishes to re-establish the current modem connection that has been placed on hold. In an actual embodiment, the DPCM will receive the reconnection indication and initiate a task 704 in response to the reconnection indication. During work 704, 'DPCM will send the appropriate reply signal.' The reply signal preferably informs APPC that the fast reconnection procedure is supported. In the embodiments described herein, this reply signal may include a suitable conversion sequence as described above. Therefore, the fast reconnection process can perform work 704, which is similar to the work 4 1 4 described above in conjunction with FIG. 4. For example, work 704 enables the DPCM to transmit the QT S signal so that APCM can again determine the timing phase of the DPCM (the QTS signal is denoted by the code 602 in FIG. 6). In addition, the retransmission of the Q T S signal will allow APCM to regain the R B S characteristics of the data communications network (if needed or desired to do so). It should be noted that for many actual modem connections, the network connection (and the related effects of digital backing and RSB) will remain the same while the modem is waiting. Of course, there may be cases where the network connection ends while the modem is waiting to save the network resources. In these cases, especially if the same network connection is no longer established, the network's digital impairment profile may not be consistent. In addition, even if the network characteristics have not changed, if the modem connection is put on hold (especially if AP CP does not receive a signal from DP CP during the wait period) AP CP will lose its R B S synchronization. In this regard, even if Ap C M can properly synchronize itself with the network timepiece again after the waiting period, the specific RB s stage still applies the Chinese National Standard (CNS) A4 specification (210 X 297 public %) _ 47-(Please read the phonetic on the back?

The description of the invention (45) is unknown. Therefore, the fast reconnection process 700 is better configured to take into account the network connection and the R B S timing has changed. The response signal also contains the appropriate sequence of signal points following the conversion sequence. Therefore, after task 704, DPCM may perform task 706 to appropriately transmit the sequence of signal points to APCM. As described above in relation to work 4 1 6, the signal point sequence can be considered as a modified answer tone, for example, the AN Sp cm signal (indicated by code 604 in FIG. 6). The ANSpcm signal 604 can be appropriately formatted to enable APCM to determine or identify the characteristics of the current communication channel or network, especially digital backing and / or other digital impairments. The A N S p c m signal 6 0 4 is also configured to provide a tone suitable for deactivating the network echo canceller and deactivating the network echo suppressor. In a practical embodiment, the AP CM would expect the transmission of the AN Sp cm signal 604. For example, APCM can be configured as a conditional receiver to receive the ANSpcm signal 604 after it sends a reconnection label to DPCM. Therefore, the fast reconnection process 7 0 0 may include a query work 7 8, which preferably determines whether the AN S p cm signal 6 0 4 has been received by the AP CM and / or whether the DP CM has received the AP CM has received the ANS.

Task 7 1 0 can cause D P CM to access previous channel information 3 4 2 and AP CM to access previous channel information 3 8 4. As mentioned above, this information may contain one or more of the following parameters: the current channel conditions (as previously determined), any number of settings related to the modem receiver, the characteristics of the communication network, and so on. Task 7 1 0 enables the modem system to quickly retrieve these stored parameters and reset the modem device in an appropriate manner to replace the independent re-evaluation of the channel and the full retraining process. Once the DPCM receives the reconnection identification tag again from the APCM, it can perform work 710, and before the APCM receives the ANSpcm signal 604, the APCM can perform work 7 1 0. If the work 710 is performed by APCM, the APCM equalizer will be initialized according to the previous channel information 3 8 4 so that the AN SP signal m 0 4 can be properly received and analyzed.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In response to the resynchronization sequence, the modem system will enter the data mode and the system will start transmitting data at the full data rate (Job 7 1 2). In other words, the data transfer mode is re-established without completely terminating the previous connection. The data pattern is represented by the sequences 6 1 4 and 6 2 0 in FIG. 6. Note that unlike the fast start process 4 0 0, the fast reconnection process 7 0 0 does not need to perform a comparison of channel characteristics (see task 4 2 0), initial training procedures (see task 4 2 2), error correction and data compression procedures ( See work 4 2 4), final training procedure (see work 4 2 8), forensic exchange (see work 4 2 8), or exchange of constellation and modem parameters (see work 430). Regarding the PAP / CHAP authentication information, the modem system can be appropriately configured to maintain the P P P / T C P / IP protocol 'during the waiting period so that the P P P authentication information need not be transmitted. As a result, the data system can rebuild its data link without wasting time performing several traditional initialization tasks. In a typical practical system, a fast reconnection process can be used to reconstruct the data pattern in less than 1.5 seconds. Another version of the fast reconnection procedure may use a timing diagram similar to the timing diagram 500 (refer to FIG. 5). However, in this embodiment, several of the above-mentioned signal sections related to the timing chart 500 may be as long as -50. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ) 499809 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. The invention description (48) has been reduced, thereby reducing the traditional reconnection time. For example, since different TRN training sequences and parameter exchange signals do not need to carry basic information, they can be shortened considerably. Because of the actual implementation requirements, you may want to keep the general sequence structure intact in this way (instead of eliminating sections from the timing diagram 500). In fact, from a software implementation point of view, the length of a segment can be adjusted in a fairly straightforward manner, and removing the entire segment from current protocols is a time-consuming and difficult task. Although the reconnection time of this another embodiment is longer than the time described above with reference to the timing chart 600 (for example, reaching 2.5 seconds), it is still longer than the time required to perform the conventional re-initialization procedure. Time is also significantly reduced. As mentioned earlier, when a telephone line is being used for modem connection, the telephone plug-in and related telephone features can be troublesome. The modem connection is usually interrupted in response to a phone call alert, and the modem device does not know the reason for the interruption. Interruption of the warning signal by the telephone may cause the modem device to go offline or enter a lengthy retraining mode. In addition, in many cases, consumers cannot take advantage of telephone plug-in services. Generally speaking, the present invention solves this problem in the following ways: (1) Allow any modem device to request an immediate call in response to a call-insertion alert; (2) Allow the first modem device to request the second modem device to enter waiting And allowing the second modem device to accept or reject the request; and (3) allowing either party's modem device to request a fast reconnection procedure (as described above). With this signaling technology, the modem connection can be terminated, put on hold, or quickly reconnected in response to an alert signal such as a phone call alert. Similarly, if the modem connection is placed in waiting, after the waiting period, the same signaling mechanism can be used to reconnect the number (please read the note on the back of the S before filling out this page)-Order --- ------ Line-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -51-499809 A7 B7 V. Description of the invention (49) The time slot of the machine. If the two-terminal device (for example, DPCM and APCM in the V.90 system) is compatible with the modem waiting characteristics, an appropriate signaling design is used to enable the end-device to switch the operation mode when needed. Although the case where the AP CM is on the client side and the d P CM is on the server or the central side of the modem system is described here, the communication design and the different processes are described. However, the present invention is not limited to this. For example, the technology described here can be equivalently applied in the case of communication activities between two customer modem devices or in the case of a V · 34 modem system. Figure 16 is a schematic illustration of an example environment in which the 6 Series modem system 600 can operate. The modem system 1 6 0 0 usually includes a first modem device 1602 and a second modem device 16 0 4. The first modem device 1 6 0 2 is related to the central side, and the second modem device 1 6 0 4 1 6 7 0 on the customer side. In a typical V · 90 system, the first modem device 1620 may be a DP CM, and the second modem device 16 04 may be an APCM. D P C M 1 600 is coupled to the central office 1606 via a digital link, and APCM 1604 is coupled to the central office 1 06 via an analog link such as a local loop. It should be understood that the computer system 1600 may include additional components and functions related to the quick start routines and / or quick reconnection procedures described above. Figure 16 also shows the calling device 16 0 8 (which can place the incoming call on the client side), the parallel answering device 16 i 0 on the client side, and the serial answering device 16 1 1 on the client side. As shown in Figure 16, the parallel answering device 16 1 0 will be connected in such a way that it conforms to the Chinese national standard (CNS) A4 specification (210 X 297 mm) in parallel with the paper size.

Invention Description (50) APC Μ 1 6 0 4 receives the same call. In contrast, the serial answering device 16 1 1 will be connected to APCM 1 604 to pass the call to it; A P c M 16 0 4 will control or adjust the call traffic to or from the serial answering device 1611 in a conventional manner. A call is established between the calling device 1608 and the answering device 1610 and 1611 via the central office 1606, and a modem connection is established between the DP 1601 and the APCM 1604 via the central office 1606. In general, modem systems can be configured to support a signaling mechanism that responds to phone calls and other situations that may require disconnecting the modem. For example, APCM 1604 can send a properly formatted signal to activate the modem waiting state, DPC M 1 600 can send a different signal to confirm the modem waiting for a request, and APC M 1604 can send another signal to request a fast The reconnection procedure (as described above) is initiated and either modem device can transmit a signal representing the end-of-session request. For the sake of brevity, Figure 16 illustrates the APCM 1604 and DPCM 1602 in a process-related manner as exemplified herein. In a practical embodiment, each modem device can be used as a transmitting or receiving modem, and each modem device can generate a different signal as described herein. The DPCM 1602 includes a transmitter area 1612 and a receiver area 1 6 1 4, both of which can be configured according to conventional techniques and according to the description of the modem system 300 (see FIG. 3).

DESCRIPTION OF THE INVENTION During the (51) mode, a signal sheet μ ^ a ^ L 'sequence and tone are transmitted. As mentioned above, the DPC M 1 6 2 can be configured to transmit the appropriate conversion sequence 1616 and the characteristic signal point sequence associated with the quick start routine or the fast reconnection procedure (for example, AN spcm signal (6 丄 8)) 1 1. During the shell material mode, DpcM 1602 will transmit data according to the appropriate data transmission design 1620. DPCM 1 602 can also be transmitted and can be received by apcM 1 64 0 and / or central office 16 6 Some signals, for example, as described here, DP CM i 6 〇2 can transmit "A" tone § week 1 6 2 and "B" tone 丄 6 2 4. In a practical embodiment, the "A" alfalfa 1δ22 is a 2400Hz tone, and the "β" is the first 1624 series 1 20 Ηζ tone (as disclosed in I TU-T recommendation V · 34). Of course, the modem device can generate and process any appropriate tone or signal to replace (or add) these predetermined tones. The DPCM 1 600 is also configured to transmit some additional signals related to the initialization of the modem standby mode, the reconnection of the modem period after the waiting period, and the termination of the modem connection. For example, DPC M 1 6 0 2 can transmit a modem waiting request 1 6 2 6, a modem waiting for confirmation 1 6 2 8, a fast reconnect request 1 6 3 0, and an interrupt signal 1 6 3 2 (herein referred to as "Modem Status Signal"). The format and function of these signals will be explained in more detail below.

For example, the signal detection element 1 6 3 4 may utilize a conventional tone detector and / or a conventional V · 3 4 or V · 9 0 differential that is configured to detect and distinguish the different signals described herein. Phase shift key (DPSK) receiver. As the signaling design described here, the APCM 1604 is preferably configured in a manner similar to D PC C 1602. In other words, APCM 1604 is capable of transmitting "A" tone 1642, "B" tone 1644, modem waiting request 1646, modem waiting for confirmation 1 6 4 8, fast reconnect request 1650, and interrupt signal 1652. In addition, the APCM 1604 can be configured to generate a caller ID tone 1654 to notify the central office 1606 that the client supports the caller ID feature (as described by the caller ID unit 1 6 5 6). According to current standards, the incoming ID tone 1 6 5 4 is a DTMF "D" tone with a length of about 55-65 milliseconds. Of course, APCM 16 0 4 will transmit data 16 8 during the data mode. As described in the above description of DP CM 1 6 0 2, APCM 1 6 0 4 preferably includes a signal detection element 16 6 0 which enables APC M 1 6 0 4 to receive, detect, and analyze Different signaling tones and sequences transmitted by DPC M 1 600. In this way, the APCM 1604 and DPCM 1602 can receive signals and can switch the operation mode in response to specific signals or received signals.

Description of Invention (53) Any number of The client-side and central office 160 can be operatively coupled to any number of other central offices, central-side modems, and so on. As briefly described above, the APCM 1604, the answering device 1610, and the caller ID component 1 6 5 6 may be located on the customer side 16 7 0. Therefore, the APCM 1604, the answering device 1610, and the caller ID component 1656 are all supported by the central office 1606. The central area 16 0 6 contains the appropriate switching structure 16 2 to route calls between the appropriate parties. For example, the switching structure 1 6 72 can be switched to the first state to establish a modem connection between DPCM 1 6 0 2 and AP CM 1 6 0 4 and switched to the second state to call the device 1 6 0 8 and A voice connection is established between the answering devices 1610. In addition, the switching structure 1 6 7 2 can temporarily interrupt the connection to transmit the control signal, data, or tone to the current circuit or office line. At this point, the central area 16 0 6 may transmit some ringing signals 1 6 7 4, warning signals 1 6 7 6, caller ID data 1 6 7 8, and other information according to specific situations. For example, according to the current method ', the central office 1660 can temporarily interrupt the voice call and send a call interruption signal 1676 to the client 1670. If the customer receives an incoming call ’, the switching structure 1 6 7 2 will be reconfigured to arrange the incoming call to the customer 1 6 6 and the original call will be placed in a waiting state. As detailed below, a similar route is used to put the modem call on hold. As mentioned earlier, the messaging design preferably uses Phase 2 messaging, which is also performed by traditional V · 3 4 and V · 9 0 Used by modem systems.

Description of the invention (54) and v · 3 4 and V · 9 0 retraining program integration. The signals are configured so that they can be detected by a V · 34 / V · 90 DPSK receiver or a fairly simple tone detector. In an actual embodiment, the modem waits for a request, the modem waits for confirmation, a fast reconnect request, and the interruption signal will lead tone A or tone B for a period of time (for example, at least 50 milliseconds). This technology balances the use of the A and B tones used in traditional V · 34 and V · 90 modem systems with the modulation design already used by modem systems. Therefore, since D P C M 1 600 is typically conditional to receive the D P S K signal, the signaling design is easy to implement. The modem-mounted signal following the A or B tone is preferably transmitted as a D P S K signal based on the repeated bit pattern. In a preferred embodiment, the modem status signal is a DPSK signal related to eight repeated four-bit patterns, where different patterns correspond to different modem status signals. It is desirable to use a four-bit pattern so that simple tone detectors can be used for the signal detection elements 1634 and 1660; shorter bit patterns result in fewer frequency components related to the .DPSK signal. As a result, the signal detection design does not need to be ordered --------- line call. (Please read the phonetic on the back?

For example, in a conventional V · 90 system, D PCM uses a signal (tone B and DPSK carrier) close to 2 400Hz, while APPC uses a signal close to 12 00 Η z. This feature is derived from the traditional V. 3 4 design. In this design, the calling modem uses a signal close to 1 2 0 0 Η ζ and the answering modem uses a signal close to 2 4 0 OH ζ. As a result, the second spectrum frequency pattern will be the same, but the Chinese National Standard (CNS) A4 specification (210 X 297 mm) will be applied at 1 200 Hz and this paper scale. 2. Description of the invention (57) 2 4 〇〇 z offset. This method ensures that the end device can properly detect the signal even when the two ends are transmitting the same type of signal. In actual systems, modem status signal detection does not need to detect the entire "spectral fingerprint" of a given signal. The signal detection elements 1634 and 1660 are configured to match and detect and analyze different numbers of frequency components. For example, as shown in Table 4, if the signal contains relatively high spectrum energy at 1050Hz and 1350Hz, the signal can be an interrupt signal or a modem waiting for a request. Therefore, the signal detection routine will continue to analyze the signal and make an appropriate decision for the spectral content of 900Hz, 1200Hz, and / or 1500 Η z. Fig. 8 is a timing chart showing a situation in which the modem connection is interrupted by a phone call and the modem connection is put on hold when the incoming call is answered by the client. Whether the client side 1670 uses a parallel answering device 1610 or a series answering device 1611, FIG. 8 can be applied. Signals, sequences, tones, commands, etc. are shown to be related to APCM, DPCM, and the central office (the central office can be related to the AP CM by a signal and the DP CM by a signal). For the sake of convenience, the processing related to FIG. 8 will be described here in the case of the modem system 1600. During the data mode, the central office 160 will temporarily disconnect the modem and send a warning signal 802 to the APCM 1604. The warning signal can be a conventional telephone plug-in warning and it contains human audible components (for example, audio tones) and components that can be detected by communication devices or machinery. According to most of the telephone interruption agreements, the warning signal components will be serially based on the Chinese paper standard (CNS) A4 (210 X 297 mm). ------------ I --- --- ^-II ^ --- IIIII-(Please read the notes on the back before filling out this page) 499809 A7 __ _B7 ____ V.

As mentioned above, the first § week 804 may be a short burst of DTMF "D" tones having a duration of about 55-65 milliseconds. Assuming that the central office i606 receives and recognizes the D T M F tone 8 0 4, it will format the incoming call data 8 0 5 and transmit it to the customer side 16 7 0. As shown in FIG. 16, the caller ID data 805 (represented by the code 1 6 7 8 in FIG. 16) is received and processed in an appropriate manner to be displayed or analyzed by the caller ID component. In response to the central office 1 606 cutting APCM 1 604 away, the DPCM will begin the retraining process by transmitting an appropriate signal such as a "B" tone 8 06. In practical applications, when the incoming call ID request 804 and the incoming call ID data 805 are being received, processed, and transmitted by the central office 1606, the "B" tone 806 is usually transmitted. When DPCM 1602 waits for APCM 1604 to reply with "A" tone 8 0, "B" tone 8 6 will be transmitted continuously. If APCM 1604 receives "B" tone 806 from DPCM 1604, it will transmit "A" clef 808. As mentioned above, the "A" tone 8 0 8 is preferably transmitted for at least a minimum duration (for example, 50 milliseconds) to give the DPCM 162 a chance to receive it. If D P C M 1 600 does not receive the "A" tone 8 0 8 within a certain period of time, it will eventually interrupt itself.

The processing shown in FIG. 9 assumes: (1) the DPCM 1602 series is in a waiting state; (2) the answering device 1610 series is connected in parallel with the APCM 1604; and (3) the answering device 16 10 terminates the incoming call, for example, Before the calling device 16 0 8 is placed on the "handset", the answering device 16 1 0 is placed on the "handset". To illustrate this point, parallel means that APCM 164 and answering device 1610 will receive the same signal from central office 1606 in a simultaneous manner. In response to the termination of an incoming call, the central office 1660 will detect "hang up" in the traditional way, for example, using the conventional office line detection technology. Finally, Central Office 1 606 disconnects or interrupts the incoming call, switches to DPCM 1602, and generates appropriate signals such as ringing signal 902. The ringing signal 9 0 2 is used to alert the user that the original call at 16 70 is still waiting and ready to connect. In response to the ringing signal 902, the APCM 1604 will be placed in the "pick up handset" so that it can receive the signal again from the central area 1660.

As described above with reference to FIG. 8, APCM 1 60 04 generates an “A” tone 9 0 4 (at least 50 milliseconds) in response to the detection of a “B” tone 9 0 6.

The characteristics, format, and functions of the Q T S signal 9 10 are as described above. If both modem devices support the above-mentioned fast reconnect feature, the waiting modem connection can be re-established in a relatively short period of time. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Figure 10 is a sequence diagram illustrating the situation where the incoming call was terminated before the parallel answering device 16 1 0 was placed under the "drop microphone". In this case, when the incoming call is terminated by the calling device 16 0 8, the central office 16 6 will reconnect the client side 16 7 0 to the original call (in this embodiment, the modem connection) ). As a result, the "B" tone transmitted by D PC C 1602 is again available at AP CM 1604. Regardless of whether APCM 1 6 04 is currently in the state of "lifting the handset" or "hanging up the handset", it will better detect whether the DPCM 602 is reconnected. It should be understood that APCM 1 604 may employ any number of conventional techniques (depending on the particular embodiment) to detect reconnections. For example, DPC M 1 600 can detect the "B" tone from DPCM 1602, which can automatically respond after a predetermined pause time, or use the technology of the office line to sense the termination of an incoming call . Once the two modem devices have regained communication with each other, the fast reconnection routine will proceed as described above with reference to FIG. 9. Regarding the situation shown in Fig. 10, it may be necessary to make APCM 1640 respond within a certain period of time to ensure that the central office 1606 does not regard the reconnection attempt as a flashing or interrupted microphone. For example, in the preferred embodiment, APCM 1 604 is configured to respond in 200 milliseconds. -64- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 499809 A7

The contents of these references are incorporated herein by reference. In general, any program used in the case of a system using a parallel answering device 16 1 0 can also be used in the case of a system using a serial answering device 16 1 1. However, the opposite is not necessarily true. For example, FIG. 11 is a sequence diagram showing a situation in which an incoming call is terminated by the serial answering device 16 1 1. As mentioned above, the communication office line at the client side 1670 first provides the signal from the central office 1606 to the APCM 1604, and the APCM 1604 will arrange the signal to the answering device 1610. In most practical applications, even if APCM 1660 only schedules the call to the tandem answering device 1611, it will still “hang up the handset”. Therefore, APCM 604 can monitor the local video to detect the presence of the "B" tone or the appropriate signal related to DPCM 1602. In this case, if the incoming call is terminated (by the calling device 16 0 8 or by the tandem answering device 16 1 1), APCM 604 can receive a signal from the central office 16 06. In addition, the central office 1606 will respond to the detection of call termination by switching DPCM 1602 to communicate with the client side 670.

Description of invention (63) (Please read the precautions on the back before filling this page) APC Μ 1 6 Ο 4 When a "B" tone is detected, it can be immediately decoupled from the tandem answering device 16 1 1. Once the two modem devices have regained communication activity, the fast reconnection routine will proceed as described with reference to the above description of FIG. Fig. 12 is a sequence diagram 'illustrating the situation in which D PC C 1620 responds to a modem waiting for a request with a call end command (Fig. 12 can be applied to a system using a serial answering device 16 11 or a parallel answering device 16 10). Until the modem waits for the request 1 2 0 2 to be transmitted from the AP CM 1 6 0 4 to the DP CM 1 6 0 2, the processing is similar to that described above with reference to FIG. 8. Unlike the case where the DPCM confirms the modem waiting for the request 1 2 0 2, the situation shown in FIG. 12 requires the interrupt signal 1204 to be transmitted from the DPCM 1602. The DPCM 1 600 can transmit the interrupt signal 1 2 0 4 after considering or considering any number of operating parameters such as the current call flow, the functional capabilities of the DPCM 1 600, channel characteristics, and the like. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs After DPCM 1602 transmits the interrupt signal 1204, it will be idle or waiting without transmitting any meaningful signal. In response to the interrupt signal 1204, the APCM 1604 will terminate the call connected to the computer in an appropriate manner. If the Central Office 16 0 6 has not detected activity from the AP C M 16 04 after an appropriate pause period such as 1550 milliseconds, it may assume that the APCM 16 04 has been interrupted. After that, the central office 1606 will switch off the DPCM 1602 and generate a ringing signal 1 2 06 and an incoming ID data 1 2 8 to the customer 1 67, so that the incoming call can be answered. After applying the appropriate standard such as two seconds to the Zhongguanjia Standard (CNS) A4 specification (210 X 297 mm) 72 " 499809 A7 B7 5. After the pause time of the invention description (64), DPC Μ 1 6 0 2 The data connection can be terminated by the data connection. During the pause time, the DPC M 1 600 has not received a signal from APCM 1 604. Therefore, once the central office 1660 starts to generate the ringing signal 1206, the DPCM 1600 will typically stop talking. As mentioned above, before stopping the call, the APCM 1604 and / or DPCM 1602 will store any relevant operating parameters to facilitate the quick start of subsequent connections. Under certain conditions, the end user may wish to immediately terminate the modem connection and accept incoming calls. Figure 13 is a sequence diagram showing the response to the alarm signal 1302. The APCM 1604 will send the interrupt signal 1 3 0 4 instead of the modem waiting for the request. Fig. 13 can be applied to a system using a serial answering device 16 1 1 or a parallel answering device 16 1 0. APCM 1 604 generates interrupt signal 1 304 in response to a user command, or automatically according to a predetermined protocol or setting. The signals and operations related to FIG. 13 are actually similar to those performed in connection with FIG. 12. However, unlike the processing shown in Figure 12, AP CM 1 6 04 will send an interrupt signal 1 3 04 to DPCM 1 6 0 2 ° Figure 14 is a timing diagram shown as a response to the warning signal 140 1, APCM 1 6 0 4 Facilitate quick reconnect procedures and ignore incoming calls.

Invention Description (65) (Please read the precautions on the back before filling this page) This situation will occur. Furthermore, this situation may occur in response to incoming call ID data, i.e. the answering party may choose to ignore incoming calls from certain callers. Up to the point where the "A" tone 1 2 0 2 is transmitted, the procedure of FIG. 14 is similar to the procedure of FIG. 8. After the “A” tone 1 2 0 2 is transmitted, APCM 1 604 will generate a fast reconnection request 1 404 ′ The fast reconnection request 1404 will eventually be received by DPCM 1602. In response to the fast reconnect request 1 4 0 4, the DPC M 1602 will send a QTS signal 1406, followed by the ANSpcm signal 1 4 0 8 to facilitate the fast reconnection routine (as described above with reference to FIGS. 6 and 7). ). It should be noted that the APCM 1604 may also transmit appropriate modem status signals such as phase reversal. The modem status signals indicate a complete retraining procedure rather than a fast reconnection procedure. In this embodiment, the retraining process is performed in a conventional manner. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Under certain conditions, the DPCM 1602 will not "automatically" enter the initial retraining mode in response to a warning signal. In other words, D P C M 1 600 will continue to transmit data as if no interruption occurred. Fig. 15 is a timing diagram illustrating this situation (Fig. 15 can be applied to a system using a serial answering device 16 11 or a parallel answering device 16 10). As described above with reference to FIG. 8, APCM 1 64 will transmit a D T M F “D” tone 1 5 0 4 (related to the caller display request) during the discontinuity in the data mode in response to the alert signal 1 5 0 2. Unlike the case of FIG. 8, D P C M 1620 starts transmitting the "B" tone due to the intermittent result. D PC C 1620 continues to send data 1506 to APCM 1604. When APCM 1604 is printed by the Central Bureau of the People ’s Republic of China, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 Public Love 1 ^ 8-printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 499809 Α7 V. Description of the invention (66) 1 6 〇 6 When reconnected, it preferably transmits "A" tone 1 508 — a suitable period of time to allow the DPC M 1 6 0 2 to respond with a "B" tone 1 5 1 0. When apc M 1 6 0 4 detects When the "B" tone from DpCM 1602 is followed by the "A" tone 1508 with S 1 GNAL a 1512, where SI GNALa 1 5 1 2 can be a modem waiting request, fast reconnect request, or interrupt signal. In response to SIGNALa 1512, DPCM 1602 will send SIGNALd 1 5 1 4 where SI GNALd can wait for the modem to confirm, QTS signal and ANS pcm sequence followed by a short silence, or interrupt signal. In this way, even DPC Μ 1 602 fails to enter the retraining mode initially with the transmission of the "B" tone, and can still handle the different situations mentioned above. The above-mentioned signaling routines and procedures with reference to Figure 8-16 can be applied equivalently Beginning with accommodation 1 6 Different requests from 70. For example, users of APC M 1 64 may wish to put the current modem connection on hold, prompt fast reconnection, or cause full retraining in an independent manner. In a practical In the embodiment, the modem waiting request and the modem waiting confirmation signal can be input into the traditional Phase 4 CP and MP sequence. Therefore, if the modem device is to wait for other modem devices (for example, a three-way call) , Request the modem device to perform rate renegotiation and transmit waiting signals in an appropriate manner. This technology can be executed in a similar end-to-end procedure as V.34 and V.90, where special codes (data rate 2 0 ) Is used to indicate the final words.

Description of the invention (67) Bit recombination or balance some reserved bits. This user request, APCM 1 6 04 will generate an appropriate data status signal (for example, modem wait request, fast reconnect request, etc.) followed by an "A" tone for reception by DPC MU 1602 . As described above with reference to FIG. 15, D PC C 1620 then responds to the following “B” tone response with an appropriate status signal (for example, the modem waits for confirmation, Q T S signal, etc.). In this way, the technology of the present invention can be applied to any situation related to telephone plug-in alert, office line interruption, or office line damage event. In one embodiment, the present invention provides techniques to reduce the initialization time and reconnection time typically associated with V.90 modem systems. Quick start and fast reconnect technologies balance the known channel characteristics of previous connections to reduce the training time associated with subsequent attempts to establish the same connection. Although not limited to any particular modem application, a quick-start procedure can be used to avoid parts of the initialization protocol or processing typically used by 56 kbps modems, for example, V. 8 bis, V. 8 digital impairment learning , Initial training, exploration and ranging, and more. In addition, compared to traditional computer startup technology, fast startup technology can perform certain operations at different times or in different orders. Referring back to FIG. 5, it is shown that during the phase 4 of the V · 90 training process, the AP CM modem 5 9 0 and the DPCM modem 5 8 0 pass through the CP and MP boxes 5 1 0 and 5 2 0, respectively.

The wave device system contains a lot of legislative information. Many other bit informations include variable length parameters that can significantly increase the length of the cps box 190. If the ITU recommendation v · 34 and V · 90 confirmation mechanisms are to be used for I TU recommendation V · 92 as described with reference to Figs. 17 and 18, the c P a box and CP a / box will contain the same The only difference is the number of bits and information. The parameter exchange and confirmation mechanisms used in the 3 4 and V · 9 0 recommendations introduce significant costs and delays in training processing. As shown in Figure 5, modems 580 and 590 will continuously transmit CP and MP frames 5 1 0 and 5 2 0 until they receive confirmation frames from the remote modem. Even if the confirmation frame introduces significant consumption and delay into the handshake process, the same previously transmitted information bits need not be transmitted again and again. Since in most cases the first transmission of the MP or CP frame will be correctly received by the remote modem, these continuous transmissions of CP, MP, CP > and MP > and Retransmission is not required. Therefore, since the confirmation bit is actually the most efficient bit information, it becomes unnecessary to transmit all the information bits in the MP / Cp / frame.
