Description of the invention (6) Lead 209, the eaves of the relay 201 are introduced 208 and 209 are connected to a local "« sound circuit 219, the operation of the mining circuit will be described below. The input leads 212 and 213 of the button 201 are connected to a thunder phone 1 (Tsl) and a Ts2 lead 213 via a switch-hook circuit 221 and 6 respectively. The relay 200 provides an off-hook (OFF-H00K) function that is well-known in the communication technology. Whenever the processor 160 sets the leads 100 and 112 to the low level, the 'top-ringing' lead of the PSTH network will be directly connected to the phone via the mold relays 200, 201 and SH detection® circuit 221 . Whenever the user picks up the phone, a demand current will appear on the leads 220-213. This current is detected by the SH detection circuit 221 (in this invention, an optocoupler) and transmitted to the lead 109 On the processor 160. When the processor 160 wishes to transmit data to the PSTN, the processor 160 activates the leads 100 and 101 so that the secondary coil of the transformer 218 is connected to the 'top-vibration' lead via the relay and a DP® circuit 214 . The DP Fenglu 214 performs a decadic pulsing as described below. To achieve this, the processor 160 transmits a continuous break-makes signal to the DP circuit 214 via the lead 101, thus opening and closing this en route. It should be noted that the ten evolutions of these intermittent signals strongly depend on the specific PSTN under consideration, and the corresponding elements that allow DCE to connect to the PSTN are stored in the table above. -The dial circuit stray circuit 217 is connected in parallel to the secondary coil of the transformer 213, and provides a short circuit of the secondary coil of the transformer when the processor generates an intermittent signal on the lead 101. To achieve this, a dial pin 104 connected to the control input of the DLS line 217 is activated. In the best practice of the present invention (please read first-back to the precautions # 塡 thing this page) --- this paper standard for easy use in the SH Jiayu standard (CNS) T4 specifications (210 to 297 male dragon) Λ 6 η 6 The Ministry of Economic Affairs is accurate and M Gongxiao 1Ϊ-Cooperative Du Yin 51 V. Description of Invention (7) In the embodiment, the dial circuit 217 is a light-following device. The PSTN table stored in the PROM memory 162 includes data that is not related to the period during which the secondary winding of the transformer 218 was short-circuited in the DLSK217. This period is one of the special PSTNs considered. -The 223 series for receiving impedance is connected between the secondary leads of the transformer 218. This method is used depending on the PSTN considered. The apparent impedance seen by "Disbel" is fixed to a decisive value. Transformer 218 is a common calendar. It can be used on a traditional coupler * Μ to provide an insulation between the basic card and the ® dial. A circuit is connected between the lead wires 206 and 207, and this "route" is composed of a Ci string targeting a resistance Ri and a string RI detection corner 224. The RI detector 224 is used to detect Lan Zhen Ling's mildew, and thus activates the RI indicator 113. The activation of the RI lead 113 can be detected by the processor 160 via the I / O circuit 165. Then, it is tested to determine whether the RI signal appearing on the lead 113 has been fully coupled to the specific PSTN box connected to the DCE. The function of the aforementioned tide test will be specifically described in the flow chart of the “Incoming Words” in Figure 5 and the description of the vibration detection process in Figure 6. The lead wires 208 and 216 of the Kan Electric 201 are connected to the secondary coil of a transformer 225 via a local feed circuit 219. The primary coil of the game controller 22 5 is quickly connected to the leads 110 and 111. Therefore, it can be turned into a green card between the basic card and the phone. However, "Note that if the above insulation is not required, the transformer 225 may be omitted. The local feeder circuit 219 can provide the DL® stream to the phone, and thus can allow the phone to function when the control processor activates the pilot 112. This local barium road can be described in detail at 7A to 7B.

Description of invention (8) Eight-bit bus 227, M-band with 8-bit wire Identification code. This identification is to be held by the holding PSTN of the coupler 150. It can be read by the control processor 160 via the four leads 105-108. The multiplexer 226 has a control lead connected to the dial circuit lead 104. When the processor 160 activates the lead 104, the multiplexer 226 sends the four maximum effective bits of the stream identification code to the pilots 105-108. On the contrary • Whenever the control processor sets the lead 104 to a low level, the least significant bit of the identification block will be transmitted to the pilots 105-108. Therefore, after encountering the two read leads 105-108, the processor 160 will derive the identification of the combiner 150, and thus the type of PSTN it can connect. As will be described in detail below, once the identification code has been confirmed by the processor 160 in an initial step, the processor will delete the corresponding element corresponding to the specific coupler connected to the basic card 120 as the RAM residual 163 in. It should be noted that for economic purposes, the mesher 150 should be as simple as possible, and should include only the hardware components required to match the desired requirements of the PSTN under consideration. In particular, the interface bus 100-112 between the basic system 120 and the combiner 150 must be as simple as possible. This can first be achieved by using the same lead 104 as the control multiplexer 226 and the control dial circuit 217 in the initial step. • The use of the same lead for two control purposes is not harmful, the multiplexer The operation of the 226 and the DL circuit 117 • Because the identification code of the coupler 150 is taken during an initial period, this period is after the source is turned on, but the control of the DL® circuit 117 is only in the initial period Effective after K. In fact, as long as the processor 160 does not communicate via the PSTN, the phone 222 is connected to the network since the guides 100 and 112 are in a low-level state.

When the power supply of the filter is turned on, the basic system 120 included in the DC E executes a sequence of source switching, which is especially present in the internal test of the machine's main excitement step 301. Then * Step 302, the processor 160 activates the lead 104 via the I / O® circuit 165, which causes the secondary loop of the secondary transformer V 18 to be short-circuited at the same time • At the same time, the 4 MSB of the identification code is transmitted to the leads 105-108, And suppress the above short circuit phenomenon. Then the LSB is stored in the RAM 163 in step 305, and then in step 306, the processor 160 compares all the 8-bit identification codes read from the multiplexer 226 with those most likely to be used by the DCE via the coupler. Table of identification codes in the connected PROM 162 (each identification code corresponds to a specific PSTN). If the code read from the coupler 150 does not match a code stored in the table stored in the PROM 162, the processor 160 stops the process of opening the source and keeps the lead ι〇〇-π2 in the low position Yes, K prevents the basic system 120 from connecting to the PSTN. Conversely, if the code output from the combiner 150 is approved, the process 160 will load the elements of the approved PSTN characteristics (such as the dial tone, vibration, etc. characteristics described above) from the PROM 163 to the RAH 162 Among them, the above-mentioned elements are characteristics of the specific PSTN connected to the coupler 150, and include test elements especially used for dial tone and vibration detection. $ · Paper-scale side-use medium aa enthalpy standard (CNS) regulations (210x297 g; «:) 44- 15139 Λ 6 W 6 Printed by the Ministry of Economic Affairs Central Standard 杓 Μ 工 消 杨 cooperative, V.

Or it comes from the user or the app that is inserted in the basic sleep 120 of the basic card 120 and starts • Step 401. In step 402, the processor 160 tests the status of the SW Junction 109. If the line is activated when the user is communicating with the phone 222 via the PSTN network, the request is aborted and the application is notified. On the contrary, the PSTN can be used during communication * and the processor 160 performs the process of 403, starting the Lijun lead 100. The processor 160 then proceeds to step 404, at which time it waits for a dial tone to appear on the S-line on the leads 202,203. The broadcast tone is transmitted to the processor 160 via the converter 171, the filter 172, and the mixer 173. The processor 160 then performs digital signal processing on the received dial tone to determine its frequency, duration and size. Once these values are all sprinkled by the processor 160, these values will be compared with the values stored in the PSTN table in the RAM 162, and after being discriminated by the coupler 150, they will be loaded with the «proper element values. Generally speaking, the PSTN table loaded in the PAM 162 exists within a range of values corresponding to a specific PSTN. For example, take the plaque as an example. • The broadcast tone received by the processor 160 must have a frequency comprised between 406 and 474 Hz. Therefore, the processor 160 can determine whether the received dial tone completely meets the requirements of the specific PSTN connected. If the measured value does not match the characteristic elements stored in the above PSTN table (this can occur when the PSTN is in a failed state or is still in the case where the user inserts an incorrect clutch 150, For example, if a coupler is not designed for the specific PSTN coupler), the process is prohibited and the leads 100-112 are maintained at a low level, so any communication between the basic card 120 and the PSTN must be prevented.

If the box requires a decimal pulse wave, the processor 160 continuously mines the start and stop leads 101 to generate a discontinuous signal. Simultaneously with this wave, the processor 160 activates the DL pilot 104 to short-circuit the secondary coil of the transformer 215. The PSTH table stored in the PAM 162 contains elements that define the activation and deactivation sequence of the dial pulse lead 101, and this element fully conforms to the PSTN under consideration. Conversely, if a DTMF pulse wave * is required, the processor 160 proceeds to step 407, at which time it generates a good tone on the leads 102-103 into the PSTN, which is based on a specific PSTN element (frequency, period ). And stored in the above table. In step 408, the processor 160 waits for an answer tone having characteristics consistent with the elements stored in the PSTN table. If an answer tone is measured, the processor 160 performs a step fee 409, and at this time, the step of playing the outgoing conversation is completed. At this time, the basic card 120 of the DCE according to the present invention is ready to communicate with the remote DCE via the PSTN. Figures 5 and 6 illustrate the process of making outgoing conversations, that is to say the steps performed by KCE to analyze the vibration signal according to the requirements of a specific PSTN.

The rectified signal Comparing with the above threshold value, a square wave signal is provided on the RI reference 113, as shown in FIG. 6E, and then the processor 160 Analyze the signal as shown in Figure 5 to determine whether the measured vibration signal is effective. The analysis of the signal begins with a trial test in step 501 * M to detect whether a negative transient occurs on the RI lead 113. When a negative transient occurs (to) • The processor 160 measures the frequency of the square wave signal on the lead 113, which is step 502. To achieve this result, the processor 160 waits for the next negative transient to appear. • If so, then Measure the interval between the two negative transients on tl T0 = U-t2. The measurement of T · processor 160 estimates the frequency value of the ringing signal, and the value is loaded with the load that has been loaded in the initial step of FIG. 3 PSTf (range comparison in the table. If the estimated value of the above-mentioned vibration frequency is not included between the maximum and minimum values in the table corresponding to the PSTN connected to DCE, the processor 160 follows the step 501. Otherwise, the process The device 160 performs step counting 503, at which time it measures the period T1 separating U instant and t2 when the next positive transient occurs. Then at step 503, the processor 160 checks whether the above measuring period T1 is included in the stored PAM 163 The value in the PSTN table is in the range K. If T1 is included in the minimum and maximum Between the value of Tim in and Tim ax, the processor 160 proceeds to step 504.

If the above value is found to be included in the authorized values T2min and T2nax range, the flow proceeds to step 505, otherwise, the processor 160 returns to step 501. The processor 160 then performs the next measurement, which includes the period T3 separating the instant T3 from the time t4 when the next positive transient 14 occurs. If the measured T3 value is included in the authorized values T3min and T3 »ax within the norm K *, the flow proceeds to step 506, otherwise, to step 501. The continuous test measurement values TI, T2, and T3 can allow DCE to be reasonably insensitive to noise that may occur at the input of the vibration detector 224. In order to improve immunity to murmurs, vibration detection 霣 路 224 also includes a Schmidt trigger (not shown in Figure 2). In step 506, the processor 160 continuously measures the encounter period corresponding to the low level of the square wave signal on the pilot 113 to detect the beginning of the off-off period Toff as shown in FIG. 6A. The device 160 compares the measured duration of the signal on the lead 113 to a low level and the second predetermined threshold value loaded into the table in the RAM 163.

This second threshold value is selected in such a way that the grabbing of the engraved line occurs approximately at the middle of the stationary Toff period corresponding to the vibration signal. It should be noted that during the Ton encounter period corresponding to the presence of mildew wire power, it is suspected that grabbing may cause large damage to the coupler 150, especially for the transformer 218. Therefore, it must be ensured that the grabbing of the telephone line does not occur when the power on the line still exists. This is achieved by comparing the low level period corresponding to the signal 113 with the second threshold stored in the RAM 163 table in the synthesizer according to the present invention.The table corresponds to the identification code of the coupler.
