Abstract

A communication session is established between an APCM modem and a DPCM modem. The central office interrupts the communication session by transmitting a call-waiting alert signal to the APCM modem. In response to the alert signal, the APCM modem transmits a caller ID data request to the central office. The APCM modem further transmits an on hold notification to the DPCM modem to prevent the DPCM modem from terminating the communication session as a result of the interruption by the alert signal and/or receipt of the caller ID data by the APCM modem. The DPCM modem is placed on hold while the APCM modem answers the call waiting. Subsequently, the APCM modem initiates a quick connect procedure to re-establish the communication session with the DPCM modem.

Scope of the invention The invention relates generally to communication systems. More specifically, the present invention relates to communications while waiting. 2. Background The Internet is widely used as a daily research, entertainment and communication tool, and the distribution of data and other communication devices has been increased. Many homes and offices use existing telephone lines to capture the Internet through modems. However, existing telephone lines can support some customer-selective features, such as call waiting features, which can disconnect a modem.

Description of the Invention (2) To avoid this interruption, many existing communication software provide users with a Option 'turn off the call waiting feature when the telephone line is in use by a modem. For example, ‘the communication software may prompt the user about whether a phone line is required to support the call waiting feature during installation. If the answer to the question is yes, the communication software can ask the user if they want to turn off the call waiting feature. Almost all users in the response want to turn off the function, because the call waiting signal may cause a disruption in the communication channel, which may cause the connection to be interrupted. For example, the communication software can dial "* 70" immediately before dialing into the network to turn off the call waiting feature. As a result, incoming calls attempting to connect the user will receive a busy signal because the call waiting feature of the telephone line has been turned off. For many users, it is not desirable to turn off the call waiting feature, as this will cause missed important phone calls. Therefore, there is a need for modems or other communication devices to effectively support the call waiting feature without causing premature communication to go offline. However, in implementing a reliable method for controlling the interruption of waiting calls, part of the recurring problem is the carrier loss of the remote modem or communication device during the waiting call caused by the central office. When the central office generates a waiting call signal on the telephone line to notify the user that an incoming call is being received, and optionally sends the caller identification information, the remote modem receives silence. This silence may be misinterpreted as a carrier miss by the remote modem. As a result, the remote modem will initiate a recovery procedure to obtain the missing carrier again. For "Hayes" compatible modems, according to modem standards, before the remote modem can go offline, the carrier must miss the time shown by the static register "10". The preset size of the static register "1 0" is based on the Chinese national standard (CNS) A4 specification (2.10 X 297 mm) (please read the precautions on the back before filling this page), and install --- ----- Yiding ____ ^ _____ · -5- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 535391 Α7 _Β7 V. Description of the invention (3) is "1 4", the unit is 0.1 second, that is, 1 · 4 seconds. Therefore, if the remote modem fails to recover the carrier within 1.4 seconds, the communication will be terminated by the remote modem. However, most commonly, the period of silence caused by a call waiting interruption can last more than 1.4 seconds. The result of a call waiting interruption will cause the remote modem to terminate communication. A simple method of this problem is to change the preset value of the static register "1 0" for the remote modem in order to obtain a longer carrier loss before the call is terminated. For example, the static register "10" can be changed to "140", which means that the remote modem must confirm the carrier loss for 14 seconds before terminating the communication. However, this method is too simplistic and is not preferred by Internet service providers and similar manufacturers because the carrier loss can be caused by various reasons. Therefore, the extension of the static register "10" is not a panacea, and has extremely adverse effects. For example, when the carrier is actually missed due to many other reasons, the Internet service provider cannot terminate the communication on time. The line is then unavailable to other users. Of course, an even simpler method is the traditional method of turning off the call waiting feature. However, all of these methods have failed to effectively remove the serious problem without causing other serious, undesired effects. Therefore, for modems or communication devices, there is an extreme need in this technology to ensure that the end-to-end communication device is waiting and to prevent the remote modem from misinterpreting the silent time as Missing carrier waves, and thus terminating communication.翌 _ 明槪述 —In accordance with the purpose of the present invention, which is widely described herein, to provide a paper size standard for the communication book China National Standard (CNS) A4 Specification 〇〇 297 公: i) (Please read the notes on the back before filling (This page) ------------- -6-Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 535391 A7 _____ B7 _ V. Description of the invention f) Method and system waiting. According to a specific embodiment of the present invention, the communication system is established between two modems, such as an analog pulse code modulation (APCM) modem and a digital pulse code modulation (DPCM) modem. The central office interrupts the communication by sending a call waiting alert signal to an analog pulse code modulation (APCM) modem. In response to the alert signal, the analog pulse code modulation (APCM) modem sends a caller identification information request to the central office. The analog pulse code modulation (APCM) modem further sends a waiting notification to the digital pulse code modulation (DPCM) modem to prevent the digital pulse code modulation (DPCM) modem from being interrupted by the alarm signal and / or This analog pulse code modulation (APCM) modem terminates communication after receiving caller identification information. In another aspect of the invention, a digital pulse code modulation (DPCM) modem responds to the modem with a wait response, including a parameter that displays the longest wait time. In another aspect, a digital pulse code modulation (DPCM) modem can respond with an offline response, showing that if an analog pulse code modulation (APCM) modem wishes to answer the call waiting, the communication will be terminated and then wait for the The analog pulse code modulation (APCM) modem responds that communication should be resumed or terminated. In one aspect of the present invention, an analog pulse code modulation (APCM) modem can send a waiting notification before receiving caller identification information from a central office. However, in another aspect of the present invention, the transmission of the waiting notification may overlap with the reception of the caller identification information of the central office. In another aspect of the invention, a digital pulse code modulation (DPCM) modem can accept an interrupt. In yet another point of view, the interruption can be negotiated between an analog pulse code modulation (APCM) modem and a digital pulse code modulation (DPCM) modem.

Description of the Invention (13) The analog pulse code modulation (APCM) modem 204 sends a call to it. Analog Pulse Code Modulation (APCM) modem 204 controls or adjusts the call message to and from the serial response device 2 1 1 in a conventional manner. A call can be set up between the calling device 208 and the answering device 2 10 and 2 1 1 via the central office 206, and a modem connection can be made through the central office 206 between the digital pulse code modulation (DPCM) modem 202 and the analog pulse. A code modulation (APCM) modem 204 is established. For brevity and simplicity, FIG. 2 depicts the example pulse code modulation (APCM) modem 204 and digital pulse code modulation (DPCM) modem 202 with the relevant example steps described herein. In a specific embodiment, each digital pulse code modulation (DPCM) modem 202 or analog pulse code modulation (APCM) modem 204 may be used as a transmitting or receiving modem, and each digital pulse code modulation (DPCM) ) The modem 202 or analog pulse code modulation (APCM) modem 204 can generate various signals described herein.

For example, the digital pulse code modulation (dpcm) modem 202 can be adapted to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) for this paper size ---- # t -------- tl- -------- Line (Please read the notes on the back before filling out this page)-16- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 535391 A7 --- B7 V. Description of Invention (彳 4) The "A" tone 2 2 2 and the "B" tone 2 2 4 are transmitted as described. In a specific example, "A" alfalfa 2 2 2 is a tone of 2 4 〇〇Η z (Hz), and "B" alfalfa 224 is a tone of 1 200 Hz (hertz) ( (As proposed by ITU-T Recommendation V · 34). Of course, the modem device 202 or 204 can generate and process any appropriate tone or signal to replace (or append to) the preset tones. Digital Pulse Code Modulation (PCM) modem 202 is also equipped to send several additional signals related to: modem waiting for notification, modem standby mode activated, modem reconnecting after waiting time, and modem connection offline . For example, a digital pulse code modulation (DPCM) modem 202 may send a modem waiting notification 225, a modem waiting request 226, a modem waiting confirmation 228, a fast reconnect request 230, and an offline signal 232 (herein referred to as a "modem Status signal "). The formats and functions of these signals are described in detail below. The digital pulse code modulation (DPCM) modem 202 may also include a signal detection element 234, which can detect, analyze, and interpret analog pulse codes using a large number of known techniques. Control signals, requests, and tones sent by the modulation (APCM) modem 204 and / or the central office 206. For example, the signal detection element 2 3 4 can be assembled using a conventional tone detector and / or a conventional V.34, V.90, or V.92 differential phase shift keying (DPSK) receiver to detect and distinguish between them. Describe the different signals. For the signaling structure described herein, the analog pulse code modulation (APCM) data machine 204 is preferably assembled in a manner similar to the digital pulse code modulation (DPCM) data machine 202. In other words, the analog pulse code modulation (APCM) modem 204 can send "A" tones 242, "B" tones 244, and the modem is waiting to be notified.

Description of Invention (15) 24 5 'Data machine waiting for request 246, data machine waiting for confirmation 248, fast reconnection request 250 and offline signal 252. In addition, an analog pulse code modulation (APCM) modem 204 can be assembled to generate a caller identification tone 254, which notifies the central office 206 that the client supports the caller identification feature (described as caller identification module 2 5 6). According to current standards, the call recognition tone 2 5 4 is a dual-tone multi-frequency (DTMF) "D" tone with a length of about 55 to 65 microseconds. Of course, the 'analog pulse code modulation (APCM) modem 204 sends data 258 during the data mode. As described above with respect to the digital pulse code modulation (DPCM) modem 202, the analog pulse code modulation (APCM) modem 204 preferably includes a signaling detection element 260 'which enables the analog pulse code modulation (APCM) modem 204 receives, detects, and analyzes each signaling tone and sequence sent by a digital pulse code modulation (DPCM) modem 202. In this way, the analog pulse code modulation (APCM) modem 204 and the digital pulse code modulation (DPCM) modem 202 can receive signals and can switch the operating mode in response to a specific signal received. The central office 206 is assembled in a conventional manner and performs circuit switching related to modems, voice and fax calls. The central office 206 can support a large number of clients, and the central office 206 can effectively connect to a large number of other central offices, central office modems, or the like. As briefly described above, the analog pulse code modulation (APCM) modem 204, the answering device 2 10, and the caller identification component 256 may reside on the client 270. The central office 206 includes a suitable switching element 272 to schedule calls between the appropriate outlets. For example, the exchange component 2 7 2 can be switched to the first state, so that the digital pulse code modulation (DPCM) modem 202 and analog pulse code adjustment can be applied to Chinese National Standard (CNS) iVl specifications (210 X 297 mm). ) -------- Order --------- Line (Please read the notes on the back before filling this page) -18- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 535391 Λ7 _____ B7_____ V. Description of the invention (16) A modem connection is established between the APC M modems and can be switched to the second state to establish a voice connection between the calling device 208 and the answering device 210. . Furthermore, the exchange component 272 may temporarily disconnect a connection in order to affect the control signals, data or tones on the current circuit or telephone line. In this view, the central office 206 may send multiple ring signals 274, Alarm signal 276, caller ID 278 and other information. For example, according to the current method, the central office 206 may temporarily interrupt the voice call and send a call waiting alert signal 276 to the client 270. If the customer accepts the imported call, the switching component 272 can be reassembled to arrange the imported call to the client 270 and put the original call on hold. As mentioned earlier, the signalling structure preferably uses a Phase 2 signalling tone, which is also used by traditional V.34, V.90 or V.92 modem systems. In addition, the signalling structure uses differential phase shift keying (DPSK) transmission technology, which enables the signal to be seamlessly combined with V.34, V.90 and V.92 retraining procedures. The signals are arranged so that they can be detected by a V.34 / V.90 / V.92 differential phase shift keying (DPS K) receiver or a relatively simple tone detector. In an actual embodiment, the modem waits for notification, the modem waits for $ 'modem waits for confirmation, fast reconnection request, and offline signals are all in the "A" tone or "B" tone for a period of time (for example, at least 50 milliseconds). This technology affects the use of "A" and "B" tones, which are used by traditional V. 34, V. 90, and V, 92 modem systems and gain the advantages of the modulation structure already used in modem systems. Therefore, since the Digital Pulse Code Modulation (DPCM) modem 202 is typically adjusted to receive differential phase shift keying, the paper size applies the Chinese National Standard (CNS) A4 specification (21〇χ 297 public love). ------ Order · -------- f Jing first read the &i; i on the back?

The invention description (17) (DPSK) signal, so this signaling mechanism is easy to complete. The modem status signal following the "A" or "B" tone can be sent in a repeating bit pattern and is a differential phase shift keying (DPS K) signal. In a specific embodiment, a modem status signal is a differential phase shift keying (DPS K) signal combined with a four-bit pattern that repeats eight times, where different types correspond to different modem status signals. The four-bit pattern is used to activate simple tone detectors for the signal detection elements 234 and 260; shorter bit patterns result in a smaller number of frequencies related to differential phase shift keying (DPS K) signals Components. Therefore, the signal detection structure does not need to use complicated processing routes to analyze a large amount of spectrum content. The bit types of different modem status signals are listed in Table 1 below.

In addition, a specific bit pattern can be appropriately selected, so that the resulting differential phase shift keying (DPSK) signal can be easily detected by a tone detector. For the bit types of the examples listed in Table 1, the modem status signal will have the frequency content listed in Tables 2 and 3, where the unit of frequency is Hertz, and "X" indicates that the spectrum content is higher than the threshold level The dash "-" indicates that the spectrum content is below the threshold level. For the differential phase shift keying (DPSK) bit pattern shown in Table 1, the lower spectral energy portion is at least 8dB lower than the higher spectral energy portion at the same frequency. Therefore, although there are some common frequency parts, different status signals of the machine can still be distinguished. .-----------— Take · --- (Please read the notes on the back before filling out this page) Member of the Ministry of Economic Affairs, W, Bureau of Industry, X Consumer Cooperative, Printed 900 975 1050 1125 1200 1275 13 50 1425 1500 DC XX ΜΗΝ XX _ΜΗ XXXXX ΜΗΑ __ XX QRR XX Table 2-Energy part of modem status signal (analog pulse code modulation (ApCM)) 丨!

Let, while analog pulse code modulation (APCM) use signaling close to 1 200 HW (Hertz). This feature is derived from the traditional V.34 architecture, in which the calling modem uses signaling close to 1 200 Hz (hertz) and the answering modem uses signaling close to 2400 Hz (hertz). Therefore, the spectral patterns of the two are the same except that they drift between 1 200 Hz (hertz) and 2400 Hz (hertz). This method ensures that even if two terminal devices send the same type of signal, they can properly detect the signal. signal. In a specific embodiment, 'data machine status signal detection need not detect the entire "feature" for a particular signal. Instead, the signal detection elements 234 and 260 can be assembled to detect and analyze a specific number of spectral portions to display a match. For example, as shown in Tables 2 and 3, if a signal is at 1050 Hz (hertz is applicable to the Chinese National Standard (CNS) A4 specification (2 丨 0 X 297) ^ --- --- -22- 4 ^^ «Is i ϋ κι I— ii I n Kas nn« 1 n ϋ I (Please read the notes on the back before filling out this page) 535391 A7 B7 V.

Therefore, the signal detection route will continue to analyze the signal at 900 Hz (Hertz), 1 200 Hz (Hertz) and / or 1 500 Hz (Hertz) spectrum content in order to make appropriate judgments. Figure 3 depicts the analog pulse code modulation (APCM) modem 310 and digital pulse code modulation.

Process display of signals, sequences, tones, instructions and similar objects and analog pulse code modulation (APCM) modem 310, digital pulse code modulation (DPCM) modem 3 50 and a central office ( (Not shown). 詨 The central office determines that it is connected to signals sent to the analog pulse code modulation (APCM) modem 310 and digital pulse code modulation (DPCM) modem 3 50. In the data mode, the central office is temporarily interrupted The modem is connected and sends an alert signal (AS) 340 to the analog pulse code modulation (APCM) modem. The Intellectual Property Bureau of the Ministry of Economic Affairs, the employee consumer cooperative prints clothes 3 1 0. The alert signal 3 4 0 may be a traditional Call waiting alert, and it includes a part that is audible to humans (such as tones) and a part that can be detected by a data communication device or machine. According to most call waiting agreements, the alert signal The two parts of 340 are sent in order. In response to the alarm signal 3 40, the analog pulse code modulation (APCM) modem 3 1 0 sends a dual-tone multi-frequency (DTMF) tone 3 14 and asks the central office to provide caller identification information. . Such as As mentioned above, the dual-tone multi-frequency (DTMF) tone 3 1 4 may be a short pulse of the dual-tone multi-frequency (DTMF) "D" tone having a length of about 55 to 65 microseconds.

Description of the invention (21) The Central Office accepts and confirms the double tone Frequency (DTMF) tone 3 14, then it will format and send the caller identification information 342 to the analog pulse code modulation (APCM) modem 310. As shown in FIG. 2, the caller identification information 342 (indicated by the number 27 8 in FIG. 2) may be received and processed in a suitable manner for display and analysis by the caller identification component 256. In response to the central office switching away from the analog pulse code modulation (A PCM) modem 3 10, the digital pulse code modulation (DPCM) modem 3 50 begins to send an appropriate signal, such as a "B" tone 3 54. In a specific embodiment, when the caller identification information 342 is sent by the central office, a "B" tone 354 may also be sent. The "B" tone 354 is continuously transmitted while the digital pulse code modulation (DPCM) modem 3 50 waits for the analog pulse code modulation (APCM) modem 310 to respond to the "A" tone 316. The central office interrupted the analog pulse code modulation (APCM) modem 310 and the digital pulse code modulation (DPCM) modem by sending an alarm signal 340 and caller identification information 342 to the analog pulse code modulation (APCM) modem 310. Communication between 350, during which the digital pulse code modulation (DPCM) modem began to receive silence. This silence may be misinterpreted as a carrier miss by a digital pulse code modulation (DPCM) modem 3 50. Conventionally, in response to a carrier miss, the digital pulse code modulation (DPCM) modem 350 starts a carrier miss timer, which is started by a user program control, such as the static register "10". The default setting of the static register "10" is in units of 0.1 seconds, and is typically set to "14", which is 1.4 seconds. If the carrier miss timer expires (after 1.4 seconds), the digital pulse code modulation (DPCM) modem 3 50 terminates the communication. Therefore, in order to avoid being used by the digital pulse code modulation (DPCM) modem during the silent period, the paper size of this paper applies the Chinese National Standard (CNS) A4 specification (2) 0 X 297 mm t.

Description of the invention (23) Send at least the minimum time. In a specific embodiment, the modem waits for 3 2 2 to be sent for 53 microseconds (all modem status signals described herein may have similar minimum times). [Please read the precautions on the back before filling out this page] In a specific embodiment, in response to the modem waiting request 3 2 2, the digital pulse code modulation (DPC Μ) modem 3 5 Ο θ sends a modem waiting Confirm (not shown) for a minimum time, such as about 53 microseconds. After the Digital Pulse Code Modulation (D PC M) modem 350 sends a modem waiting request 35 6 (or alternatively the modem sends a modem waiting for confirmation (not shown)), the digital pulse code modulation (DPCM) modem 3 50 compares Jade continues to send a "B" tone of 358 while keeping it waiting. In response to the modem waiting for confirmation (not shown) or after a predetermined time, the analog pulse code modulation (APCM) modem 310 can generate an appropriate flashing signal 324 to instruct the central office to switch away from the data. Data line And switch into the incoming call. In addition, returning to Figure 2, the mobile phone (or other appropriate answering device) begins to receive incoming calls; the analog pulse code modulation (APCM) modem 204 can be assembled to An appropriate way to arrange the incoming call is to a parallel answering device 2 10 or a tandem answering device 2 1 1. In addition, when the mobile phone is connected, the analog pulse code modulation (APCM) modem 204 may be idle or "on-hook". Therefore, the user of the client 270 can handle the incoming call while the digital pulse code modulation (DPCM) modem 202 is waiting. The modem connection can be re-established by the fast modem reconnection procedure described in the above-mentioned related application. Refer to Figure 4, which shows the analog pulse code modulation (APCM) modem 41 and the digital pulse. Timing chart of the communication between 450 DPCM modems, which is a paper size applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -26- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 535391 A7 B7 V. Description of the Invention (24) The call waiting instruction was interrupted, wherein the modem connection was offline before the incoming call was answered by the terminal of the analog pulse code modulation (APCM) modem 410. As shown, the processes before the modem waits for notification 418 from the analog pulse code modulation (APCM) modem 410 to the digital pulse code modulation (DPCM) modem 450 are similar to the relevant points in FIG. 3 described above. However, compared with FIG. 3, the digital pulse code modulation (DPCM) modem 3 500 responds to the modem wait request 356 with a modem wait request 356, and the situation depicted in FIG. 4 shows that the digital pulse code modulation ( DPCM) modem 450 sends an offline signal 456. By sending an offline signal 456, the digital pulse code modulation (DPCM) modem 450 notifies the analog pulse code modulation (APCM) modem 410. If the analog pulse code modulation (APCM) modem 410 decides to answer the incoming call, then The digital pulse code modulation (DPCM) modem 45 0 will be offline. After sending the offline signal 45 6, the digital pulse code modulation (DPCM) modem 450 continues to send a “B” tone 45 8 while waiting for a response from the analog pulse code modulation (APCM) modem 410. At this time, the analog pulse code modulation (APCM) modem must decide whether to ignore the incoming call and keep the modem connected, or to answer the incoming call and lose the current modem connection. Figure 4 depicts an analog pulse code modulation (APCM) modem 4 1 0 that decides to answer the incoming call. In this way, after receiving the digital pulse code modulation (DPCM) modem 450 offline selection (if the analog pulse code modulation (APCM) modem 410 will answer the incoming call), the analog pulse code modulation (APCM) ) The modem 410 sends an "A" tone 420 before the offline signal 422. The offline signal 422 informs the digital pulse code modulation (DPCM) modem 450 of the decision of the analog pulse code modulation (APCM) modem 4 10 in order to terminate the communication. Analog Pulse Code Modulation (APCM) modem 410's decision to terminate communication This book uses the Chinese National Standard (CNS) A4 specification (210 > < 297 km ¥) (Please read the precautions on the back before filling out this page ) Yi-27- Employees of Intellectual Property Bureau of the Ministry of Economic Affairs printed 535391 A7 ___ B7_ V. Invention description (25) can be made automatically by host software 105 (see Figure 1), or the user responds to the host software 105 Ask and make that decision. In a specific embodiment, after the digital pulse code modulation (DPCM) modem 450 sends an offline signal 456, it waits idle or without sending any meaningful signals. In response to the off-line signal 456, the analog pulse code modulation (APCM) modem 410 eliminates the modem connection in an appropriate manner and does not send the "A" tone 420 and off-line signal 422 sequences. If the central office does not detect the activity of the analog pulse code modulation (APCM) modem 410 after a suitable interruption time, such as 1550 microseconds, then the central office will assume analog pulse code modulation (APCM) data Machine 410 is offline. After that, the central office will switch off the digital pulse code modulation (DPCM) modem 450 and generate a ring signal 428 to the client so that the incoming call can be answered. The Digital Pulse Code Modulation (DPCM) modem 450 can also delete its modem connection after an appropriate interruption time, such as 2 microseconds, during which it has not received analog pulse code modulation (APC Μ) data. Machine 4 1 0 signal. Therefore, once the central office begins to generate the ring signal 428, the digital pulse code modulation (DPCM) modem 4 50 will typically be put on hold. Of course, as explained in the related application incorporated above, before the connection is deleted, the analog pulse code modulation (ApCM) modem 41 and / or the digital pulse code modulation (DPCM) modem 450 can store a large number of Related operating parameters to facilitate subsequent quick connection. Fig. 5 shows a timing diagram of the communication between the analog pulse code modulation (a PC M) modem 5 10 and the digital pulse code modulation (DPCM) modem 550, which is "interrupted by a call waiting indication, in which the modem The connection is dried up by analog pulse code modulation (ApcM); the fast reconnection request (QRR) of the 5 10 Z terminal is restored. Same as ----------- Aw · Μ --- I I ---- ^ --------- (Please read the precautions on the back before filling this page) 535391 Λ7 B7 5. According to the description of the invention (26), the process before the modem waits for notification 5 1 8 is transmitted from the analog pulse code modulation (a PC M) modem 510 to the digital pulse code modulation (DPCM) modem 550. The above-mentioned FIG. 3 is similar. However, compared to FIG. 3, the analog pulse code modulation (APCM) modem 310 responds with a modem wait request 322 to the digital pulse code modulation (DPCM) modem 350. The modem waits for a request 3 5 6 while in FIG. 5 The depicted situation shows that a fast reconnect request signal 522 is sent to a digital pulse code modulation (DPC M) modem 5 50 0, preceded by an "A" tone 5 20. By sending a fast reconnection request signal 522, the analog pulse code modulation (APCM) modem 510 notifies the digital pulse code modulation (DPCM) modem 550 that it wishes to maintain communication regardless of incoming calls. This situation can occur when the quality of the modem connection is important, the incoming call that the end user does not want to be interrupted, and / or if the modem connection is severely affected by the alarm signal 5 40. Furthermore, such situations may occur in response to the incoming call identification data 542, that is, the answering device may choose to ignore incoming calls of certain calling devices. In response to the fast reconnection request signal 522, the digital pulse code modulation (DPCM) modem 5 50 may send a QTS signal 558 before the ANSpcm signal 560 to facilitate the fast reconnection as described in the related application filed above. Line by. It should be noted that the analog pulse code modulation (APCM) modem 510 may instead transmit an appropriate modem status signal, such as an inverted signal, which shows a complete retraining procedure rather than a fast reconnection program. In one such embodiment, the retraining procedure will be performed in a conventional manner. The above-mentioned signaling routes and procedures related to Figs. 3 to 5 can also be applied to facilitate various requirements originating from the client 270 (see Fig. 2). For example, in Figure 3, the paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page).

Description of the invention (27 ), Users of Analog Pulse Code Modulation (APCM) modems 3 10 may seek to wait for the current modem connection to trigger a quick reconnection, or to trigger a complete retrain in a separate manner. In a specific embodiment, the modem waiting notification (MHN) and modem waiting request (MH) signals can be input into the traditional phase 4 clustering parameter (CP) and modulation parameter (MP) sequences. Therefore, if any modem device wishes to put another modem device on hold (for example, for a three-party call), the requested modem device can perform re-negotiation of the transmission rate and transmit the wait signal in an appropriate manner. . This technique can be implemented in a similar manner to the conventional erasure procedures of V.34, V. 90 and V. 92, in which a specific code (data transmission rate = 0) is used for display erasure. However, the modem waiting signaling technology may use different bits to synthesize or affect multiple reserved bits. Therefore, in these specific embodiments, the interruption of the communication channel (such as a control signal, data or tone) may come from one of the communication devices, rather than the central office. Furthermore, the interruption can occur during the negotiation phase between communication devices, or after the communication device enters the data phase. In response to a user of the Analog Pulse Code Modulation (APCM) modem 3 1 0 requesting that the connection be placed on hold, the Analog Pulse Code Modulation (APCM) modem 310 can generate an "A" tone followed by a digital pulse Code Modulation (dpc μ) Modem 3 50 0 The appropriate modem status signal received by the modem (for example, modem waiting notification, modem waiting request, fast reconnection request or similar signal) ◦ As mentioned above related to Figure 3 'Digital Pulse Code Modulation (DPCM) modem 3-50 may respond with a "B" tone' followed by an appropriate status signal (eg, modem waiting request, QTS number, or similar signal). In this way, the technique of the present invention can be applied to a large number of situations, with call waiting alerts, line interruptions, or lines

Description of the invention (28) The bad situation is not relevant. Referring to FIG. 6, it depicts a customer modem, such as an analog pulse code modulation (APCM) modem, which can be taken in response to receiving a caller identification data from a central office when communicating with a digital pulse code modulation (DPCM) modem. An exemplary flowchart of the steps. As shown in the communication waiting procedure 600, the analog pulse code modulation (APCM) modem continuously monitors the alarm signal generated by the central office in step 610 on the line. Once the alarm signal is detected, the routine 600 proceeds to alarm signal step 615, where the alarm signal is acknowledged. After confirming the alarm signal, the analog pulse code modulation (APCM) modem proceeds to a dual-tone multi-frequency (DTMF) step 620. In step 620, the analog pulse code modulation (APCM) modem sends the "d" tone to the central office as described above to request the caller identification data to be transmitted to the analog pulse code modulation (APCM) modem. At this time 'the analog pulse code modulation (APCM) modem self-assembles to receive the caller identification information. For example, the analog pulse code modulation (APCM) modem receiver can be assembled into a V.2 1 operation to receive the caller identification information. This analog pulse code modulation (APCM) modem pj * is further equipped to detect the "B" tone of a digital pulse code modulation (DPCM) modem. As shown in FIG. 6, after the “〇” tone is sent in step 62, the program 600 may start a multi-tasking task, in which the program 600 simultaneously monitors the online digital pulse code modulation (DPC M) modem in step 6 respectively. Caller ID information and "B" tone sent in 2 5 and 6 3 0. Once the "β" tone is received, the procedure 600 switches to step 6 3 0, where it is confirmed that the "β" tone lasts for a predetermined period of time, such as 10-20 microseconds. At this time, in order to avoid the digital pulse code modulation (DPCM) modem from misinterpreting as a carrier loss, the program 600 will switch to step 635 (please read the precautions on the back before filling this page) «n ι .ϋ j n-n port, MM aaam MM--mm mw mm employment

Description of the Invention (29) 'With Medium_, Pulse Code Modulation (APCM) Modem As described above, before sending a modem waiting for notification, it sends an "A" tone to the Digital Pulse Code Modulation (DPC M). ) Modem. In some specific embodiments, as a result of the procedure, the modem waits for sending the notification in step 635 before the receipt of the caller identification information in step 625 or overlaps it. Program 600 then transitions to a wait state of 64 °, where the analog pulse code modulation (APCM) modem is waiting for a response from the digital pulse code modulation (DpcMC) modem. However, at the same time, analog pulse code modulation (eight ... ⑷ modems can receive caller identification information from the central office. In a specific embodiment, once the caller identification information is received, it can be formatted and displayed so that The user uses it in step 6 2 7. Return to wait state 640, as shown in steps 645, 650, and 65.5, respectively. The digital pulse code modulation (DPCM) modem can respond to the analog pulse code modulation (APCM) in two ways. ) The modem notification, or if the DPCM modem does not support the modem wait feature, it does not respond. The DPCM modem can use the modem as shown in step 645. Waiting for a response request (Μ 要求) instruction, so that the procedure 600 proceeds to one of three steps 660, 670, or 675. As to which step to choose, it can be automatically performed by the APCM modem according to the For example, an analog pulse code modulation (APCM) modem or host software can check the caller identification data against the stored information. However, the decision can also be made by the user in step 629 in response to the display in step 627 Caller ID information. In the first option, the procedure 600 may proceed to state 660, where an analog pulse code modulation (APCM) modem requires a digital pulse code modulation (DPCM) modem to wait.

Description of the Invention (30) (Please read the notes on the back before filling this page) Secondly, the procedure 600 switches to the blinking step 665, where a blinking signal is used To terminate the incoming call while the digital pulse code modulation (DPCM) modem is waiting. In a specific embodiment, step 660 can be skipped, and the procedure 600 directly proceeds from step 645 to flashing step 665. In another specific embodiment In an embodiment, the analog pulse code modulation (APCM) modem may wait for the modem to wait for confirmation after step 660 and before proceeding to the blinking step 665. However, in the second option, the program 600 may receive a digital pulse Code modulation After the modem of the DPCM) modem waits for a request (MH), it switches to the offline state 670. Similar to the first option, the second option can be automatically or determined by the user. As shown, during the offline step, the program 600 sends an "A" tone to the digital pulse code modulation (DPCM) modem before the offline request (DC) to terminate the communication. In the third option, the procedure 600 switches to the fast reconnect state 675, of which analogy The pulse code modulation (APCM) modem ignores the incoming call and asks the two modems to resume their interrupted communication by using the fast connection structure described in the related application incorporated above. In some embodiments, the modem will be retrained in a traditional manner. M. to the intellectual property yf employees; r co-operatives to go to wait state 640, the digital pulse code modulation (DPCM) modem responds to the analog pulse code with an offline (DC) instruction as shown in step 650 (APCM) modem notification. The analog pulse code modulation (APCM) modem receives the offline (DC) indication, indicating that if the analog pulse code modulation (APCM) modem wants to answer the incoming call, the digital pulse code modulation (DPCM) modem will Offline. In step 650, the analog pulse code modulation (APCM) modem has two available options, shown in steps 670 and 675. As mentioned above, these options can be automatically applied to paper & China National Standard (CNS) A4 specifications (2) 0 X 297 mm. 33- Printed by the DM Workers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 535391 A7 B7 5 , Invention description (31) or determined by the user. In step 650, the user may also be notified of the intention of the digital pulse code modulation (DPCM) modem to go offline, so the user may make a further notification decision. If the decision is made to answer the incoming call, the process 600 proceeds to state 670 as described above to terminate the communication. Alternatively, if the decision is made to ignore the incoming call and resume communication, the process 600 transitions to a fast reconnect state 675. As described above, the digital pulse code modulation (DPCM) modem may not respond to the analog pulse code modulation (APCM) modem at step 635, waiting for confirmation. As a result, the wait state 6 40 will be suspended at last, and the program 6 00 will proceed to step 65 5. In step 6 55, the procedure 600 may notify the user of the status and request a response, or may automatically decide to go to the blinking state 665 or the fast reconnecting state 675. If the blinking state 665 is selected, the analog pulse code modulation (APCM) _ will stop incoming calls, and the digital pulse code modulation (DPCM) modem will go offline after a pause. On the other hand, if you enter the fast reconnect state 675, the analog pulse code modulation (APCM) modem will ignore the incoming call, and the modem will try to reconnect. Figure 7 depicts an exemplary flowchart of some detailed steps taken by an analog pulse code modulation (APCM) modem while the modem is waiting. As shown, the analog pulse code modulation (APCM) procedure 700 is initiated by receiving an alarm signal from the central office in step 710, which causes the procedure 700 to proceed to alarm signal step 715. In the alarm signal step 715, confirmation of the alarm signal is performed. At this time ', in some specific embodiments, the analog pulse code modulation (APCM) program 700 may enter a multi-tasking mode, where the program 700 simultaneously monitors the caller identification data of the digital pulse code modulation (DPCM) modem on the communication line and "B" tone.

At this time, the analog pulse code modulation (APCM) program 700 enters the waiting state 7 3 5, where the analog pulse code modulation (APCM) program 700 waits to receive digital pulse code modulation before the differential phase shift keying (DPSK) response. (DPCM) The "a" tone of the modem is about 10-20 microseconds. According to the differential phase shift keying (DPSK) response of the digital pulse code modulation (DPCM) modem, the analog pulse code modulation (APCM) program 700 can enter the state 740. This paper size applies the Chinese National Standard (CNS) A4 specification (2 : 10 X 297 mm) (Please read the notes on the back before filling in this page) · ϋ nnn I nnr «It nnnnnn I» -35-Intellectual Property Bureau, Ministry of Economic Affairs, Employee Consumer Cooperative, Printing and Agriculture 535391 Λ7 B7____ V. Invention Note (33), 745 or 750. These steps are as described in FIG. 6. Figure 8 depicts an exemplary flowchart of some detailed steps taken by a digital pulse code modulation (DPCM) modem while the modem is waiting. As shown, when a digital pulse code modulation (DPCM) modem begins to receive silence from an analog pulse code modulation (APCM) modem, and the analog pulse code modulation (APCM) modem is sending an alert to the central office When the signal and caller identification data are interrupted, the digital pulse code modulation (DPCM) procedure first experiences carrier loss. When a carrier loss is detected, the digital pulse code modulation (DPCM) procedure 800 proceeds to a carrier loss state 815. In this state, the digital pulse code modulation (DPCM) program 800 proceeds to step 820, reads the contents of the static register "1 0", and starts a 0.1 second timer according to the value of the static register "10". . As mentioned above, the default value of the static register "10" is "14". As a result, digital pulse code modulation (DPCM) modems are given 1.4 seconds to recover from carrier loss. The Digital Pulse Code Modulation (DPCM) program 8 00 starts to produce a “B” tone, activates the “A” tone detector and differential phase shift keying (DPSK) detector, and simultaneously activates the static register. After the digital pulse code modulation (DPCM) modem is assembled in step 820, the digital pulse code modulation (DPCM) program 800 transitions to state 825, waiting for the modem receiving the analog pulse code modulation (APCM) modem to wait for notification. . It is important that the digital pulse code modulation (DPCM) program 800 receives the modem waiting for notification before the static register "10" has finished timing. In addition, for many reasons, it is important that an analog pulse code modulation (APCM) modem send the modem to wait for a notification in about 1.4 seconds. For example, for a "Hayes" compatible modem, the default register "10" is set to "14", and this paper applies the Chinese National Standard (CNS) A4 specification in many installed paper sizes ( 210 X 297 mm) #it -------- tr --------- (Please read the precautions on the back before filling this page) -36- 535391 A7 B7 V. Description of the invention ( 34) The modem remains unchanged. In addition, since the static register "丨 0" is a general-purpose register and is suitable for all carrier miss situations, in order to avoid the single purpose of being offline while the modem is waiting, it is extremely reluctant to add a static register. "10" 値. The increase of the static register "1 〇" will cause the digital pulse code modulation (DPCM) modem to wait longer when the carrier is truly missing. Referring to FIG. 8, if the digital pulse code modulation (DPCM) modem does not receive the “A” tone of the analog pulse code modulation (APCM) modem, the digital pulse code modulation (DPCM) program 800 proceeds to the offline step. 830, where the communication is terminated. In some embodiments, the digital pulse code modulation (DPCM) modem may enter a retraining step (not shown) instead of terminating communication. On the other hand, if the digital pulse code modulation (DPCM) modem receives the "A" tone of the analog pulse code modulation (APCM) modem and the modem waits within the time allocated by the static register "1 0" If so, the digital pulse code modulation (DPCM) procedure 800 proceeds to step 835. Once the modem wait notification is received, the digital pulse code modulation (DPCM) program 800 must determine whether to accept the analog pulse code modulation (APCM) modem in a waiting state, or if the analog pulse code modulation (APCM) data is accepted. The machine will continue to wait for the program, then notify the analog pulse code modulation (APCM) modem, and the digital pulse code modulation (DPCM) modem wants to terminate the communication. Digital Pulse Code Modulation (dpcm) modems can automatically make judgments based on some preset conditions or user responses. In any case, if the digital pulse code modulation (DPCM) program 800 is in state 840, a modem waits for a differential phase shift keying (DPS K) signal to send an "A" tone to analog pulse code modulation (APCM) data. To send an "A" tone before an offline differential phase shift keying (DPSK) signal in state 845.

Description of the Invention (35) Analog pulse code modulation (APCM) modem. As a result, the digital pulse code modulation (DPCM) program 800 notifies the analog pulse code modulation (APCM) program 700 'to accept or hack the modem waiting program. In some specific embodiments, the digital pulse code modulation (DPCM) program 800 may also send a parameter indicating the time that the digital pulse code modulation (DPCM) modem can be placed in a wait state to the analog pulse code modulation in step 840. (APCM) modem. After the digital pulse code modulation (DPCM) program 800 sends a response in state 840 or state 845, the digital pulse code modulation (DPCM) program 800 enters state 850, where the digital pulse code modulation (DPCM) program 800 starts sending A "B" tone activates the "A" tone detector and differential phase shift keying (DPSK) signal detector. The digital pulse code modulation (DPCM) program 800 then advances to the waiting state 85 5, where the digital pulse code modulation (DPCM) program 800 waits for a response from the analog pulse code modulation (APCM) modem as shown in the relevant description of FIG. 6. FIG. 9 depicts a flowchart 900 of a modem in a wait state, in which communication of an analog pulse code modulation (APCM) modem is put on wait. As shown, after the communication is interrupted, the digital pulse code modulation (DPCM) program transitions from the initial state 950 to the state 955, where the digital pulse code modulation (DPCM) program starts sending a "B" tone to the analog pulse code modulation (APCM) modem. At the other end of the connection, the analog pulse code modulation (APCM) program is in its initial state 9 1 0, which receives the "B" tone and transitions to state 9 1 5 in response, where the analog pulse code modulation (APCM) The program sends an "A" tone before a modem waits for notification. At the other end, the digital pulse code modulation (DPCM) program is in state 960. Before a modem waits for a request signal, it sends an "A" tone to notify the analog pulse code modulation (APCM) modem.

Description of the invention (36) Waiting state. As shown, the modem wait request signal may include a "Ta" parameter that indicates how long the digital pulse code modulation (DPCM) modem can be placed in a wait state. After receiving the "a" tone and modem waiting for a request signal, the analog pulse code modulation (APCM) program must advance to state 920 within the "Tb" time, for example, 50 to 100 microseconds, otherwise the digital pulse code modulation (DPCM) modem will terminate the modem waiting procedure. The analog pulse code modulation (APCM) program in state 920 requires the digital pulse code modulation (DPCM) program to transition to wait state 965. At this time, the digital pulse code modulation (DPCM) program enters the waiting state 965 and starts the "Ta" time timer, for example, 60 seconds. When the “Ta” timer is finished, the digital pulse code modulation (DPCM) procedure terminates the communication. On the other hand, the analog pulse code modulation (APCM) program waits for a "Tc" time, such as 100-150 microseconds, before sending a flash signal to the central office to stop the incoming call. The purpose of the "Tc" time delay is to confirm that the Digital Pulse Code Modulation (DPCM) procedure has entered the wait state 965.
