'The extension transmission system has a connection switch. The first monitoring device on the side; the second monitoring device on the terminal device side; and the extended transmission path between the first monitoring device and the second monitoring device. The second monitoring device can be detected by the two monitoring devices. When a fault occurs on the terminal device side, the fault information indicating the fault is notified to the first monitoring device. When the first monitoring device detects the fault information notified from the second monitoring device, it causes the switch side to output. The signal state is formed as no signal state or signal synchronization loss state, and the above-mentioned failure can be notified to the switch side. Printed by the 8th Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Line Economy If the interface of the subscriber line on the home side of the subscriber is abnormal, the subscriber line on the central office side will be referred in advance. The signal state is set to no signal state or signal synchronization loss state. When this abnormality occurs, the subscriber line interface on the central office side can form the above signal state, and the switch can be notified of the occurrence of obstacles, thereby monitoring the extended subscriber circuit. In the loop monitoring system, once the first monitoring device detects a failure of the extended transmission path or the second monitoring device, the signal state of the output switch can be turned into a no-signal state or a signal synchronization loss state.

Also, in the specifications of the transmission frames of the existing subscriber line interface 3 4, 4, 3, and 5 3, the unused bits in the M channel are used to monitor the central office 3 through the extended transmission paths 6 1 and 62. Device 3 2, 3 3 sends the RKD signal. Hereinafter, an example using the M channel will be described below. This method specifically refers to the portion of the M channel in the transmission frame that can be fixed with "1" or n i b. In addition, n i b is the above-mentioned future reserved bit, at least a bit not defined by A N S I. As described above, in this embodiment, multiple R K D signals are given to empty channels other than the main signal (2B + D in I SDN), which can be sent to the central office 3 side sender. The difference in the configuration of the monitoring device 3 2 and 3 3 of the central office 3 is only a difference in the plural circuits.

Once the input user data is recorded in the transmission I F 0 71, the data of the basic frame and the M channel (M c h) are collected by the frame 7 2 to form a super frame. The sending circuit 7 3 sends the super frame to the switch 3 1 through the external loop interface 7 4. The receiving circuit 75 receives signals from the switch 3 1 through the external loop interface 7 4. A clock component is extracted from the received signal by the demodulation circuit 76 and the clock regeneration circuit 77. The clock generation circuit 78 is used from the switch 3 1 to the network terminal unit 4 2 and 5 2 to 5 2.

In addition, the control means 3 3 ″ sequentially outputs the data of the M channel of the entire loop through the serial bus 3 3 η to the time-sharing switch 3 3 c at the timing of time slot 0. Furthermore, the 'monitoring device 4 1 and 5 1 are also connected to the subscriber line interface 4 3, 5 3 to 5 3 to form the network terminal portion 4 2, 5 2 to 5 2 and the extension transmission path 6 1' 6 2 is in addition to Except for the point where the monitoring devices 3 2 and 3 3 are formed, the configuration is the same as that of the monitoring device 33 shown in FIG. 3.

Inventions Explanation (1 {)) In addition, the time slots I 9 to 2 on the extended transmission paths 6 i and 6 2 are allocated to the data among the monitoring devices. The time slots 2 4 to 3 1 can be ignored in the high-speed loop framer 3 3 b to form time slots that do not exist on the extended transmission paths 6 1 and 6 2. Next, the operation during the R K D process of forcibly stopping the monitoring device 33 from supplying the signal to the switch 31 will be described below. Furthermore, in this embodiment, an example is to accept a clock signal from the first subscriber line interface 3 4, and to describe a case where a failure occurs in correspondence with the first subscriber line interface 5 3. First, when a failure such as the disconnection of the first subscriber line interface 5 3 occurs, the monitoring device 51 detects the first subscriber line interface 5 after, for example, a period of about 480 ms determined by the ANSI. 3 broken links. In addition, the monitoring device 5 1 immediately sets the broken link information in the transmission frame in the extended transmission path 6 2, and changes the empty channel in the M channel corresponding to the first subscriber line interface 53 from “1” to “〇. ", Send it to the monitoring device 3 3 as RKD signal. As shown in FIG. 3, the monitoring device 3 3 makes the high-speed loop framer 3 3 b via the extended transmission path 6 2 and the high-speed loop interface processing unit 3 3 a to switch the time division switch 3 3 c. In this frame, the μ channel ′ is separated and transferred to the control means 3 3 ″. The user data of 2 B + D in the transmission frame is output to the u-I / F processing unit 3 3 d to 3 3 g of the circuit corresponding to the time-sharing switch 3 3 c.

Description of the invention k) Corresponding to this, the U-I / F buried part (for example, 3 3 d) is moved to RKD for processing. Before this processing, the control means 3 3 ″ can investigate the signal states of each of the u-I / F processing sections 3 3 e to 3 3 g. In addition to the control means 3 3 j, in addition to the U-I / F processing section 3 3 d that performs RKD processing, at this time, the clock is controlled to resupply an effective clock supply source to the U-I / F processing section 3 3 d. The conversion of the source selection means 33h resets the clock supply source, and houses the clock signal of the clock generation circuit 78 of the newly selected U-I / F processing section (for example, 33d). In addition, at this time, it is also considered that there is no effective U-I / F processing unit with a clock supply source. Therefore, the timing generating means 3 3 1 has a self-excitation function in advance, and the timing generating means 3 3 1 can also be self-excited. The excitation clock source is set to the clock supply source for synchronization. When the switching of the clock supply source is completed, the next control means 3 3 j for the U _ I / F processing section 3 3 d temporarily makes the subscriber line interface 34 on the switch 3 1 in a no-signal state or loses signal synchronization. State, the control signal can be sent out via the bus 33k. This control signal enters the control circuit 8 2 from the C P U bus in the U-I / F processing section 3 3 d via the C P U control 璋 8 3. The control circuit 8 2 controls, for example, the stop of the framer 7 2, the transmission circuit 7 3, the reception circuit 75, and the deframer 80, and can stop the function of the subscriber line interface 34. In addition, the control means 3 3 j of the monitoring device 3 3 can also detect I interruptions in the extended transmission system such as the monitoring device 5 1 and the extended transmission path 6 2 _ in the house. That is, when the extended transmission system fails, the state of the high-speed loop framer 3 3 b becomes a no-signal state. The control of the segment 3 3 j can detect the Asahi U number.

Therefore, in addition to detecting the no-signal state or the loss of signal synchronization, the switch 31 can detect a failure, and at the same time, it can prevent synchronization abnormality caused by clock signal deviation in other circuits when R K D of a certain circuit. As described above, in this embodiment, after switching the clock supply source to another clock supply source before RKD, the interface of the joiner line forming the clock supply source where the fault occurred is RKD, so it will not cause any adverse effects on other circuits at all. Switch to a good clock supply source. Furthermore, in this embodiment, although the above-mentioned clock supply source switching process is performed, all U reference points of the monitoring devices 4 1 and 51 are connected to the same clock source to obtain a fully synchronized operation. The variation of the clock signal of the monitoring devices 41, 51 does not constitute a problem. In this embodiment, the time difference between the clock switch and the RKD of the subscriber line interface 34 on the switch 31 side can be set arbitrarily. For example, the maintenance bit (M bit) usually used in the basic interface of I S D N can be recognized for more than 3 frames t (that is, 36 ms) and can be determined by A NS, so a time difference of about 36 ms can be set accordingly. At this time, for example, when using the η 1 b bit to perform the instruction from the monitoring device S4 1, 5 1 to the RKD of the monitoring device 3 2, 3 3, as long as it is common to identify the standard M frequency free paper size National Standard of China (CNS) Α4 specification (2! 0 × 297 mm) ---------- install-(Please read the precautions on the back before filling in this page).,? τ Ministry of Economy Printed by the Intellectual Property Bureau's Consumer Cooperative Cooperatives-16- Printed by the Intellectual Property Bureau's Employee Cooperative Cooperatives 4209 18 Λ7 B7 V. Description of the Invention L) The time difference of the same state change is 3 6 ms, and the time difference can be set very easily The functions are incorporated in the monitoring devices 3 2, 3 3. For example, when the monitoring device 3 2, 3 3 initially detects η 1 b = 〇, the time source switching is started on the preventive measures, and nib = 〇 lasts for 3 frames (36 ms). In the processing mode, the function can be assembled very easily. It is to be expected that the time difference is set due to the switching speed of the clock signals inside the monitoring devices 3 2 and 3 3. Generally, the switching of the clock supply source should be completed within 1 m s, but for safety reasons, a long time difference α can be set sufficiently, for example, 4 8 m s of 4 frames or a time difference of about 100 ms can be set. In this embodiment, when the extended transmission paths 6 1 and 6 2 are cut as described above, it is preferable to cut off all the subscriber line interfaces 34. As a result, all clock supply sources can be cut off, so the subscriber line The status judgment of interface 34 is meaningless. Therefore, in the present invention, 1 can be monitored by the monitoring device 4 on the 3rd side of the central office or on the 4th and 5th sides of the subscribers 'homes 4 and 5 1 to determine whether to cut off all the subscribers' line interface 3 4 at the same time. The algorithm can also be assembled if necessary Switching of this clock supply. In addition, in the case where the all-joiner line interface 34 is cut off, the clock supply from the monitoring devices 4 1 and 5 1 on the joiner's house 4 and 5 sides can be temporarily cut off. In this case, the operation of the IS D N extension device can also be performed reliably. Therefore, it is also possible to have a constituent of the self-excited clock source internally 'until the self-excited clock source is stable. It is necessary to consider that a time of 1 mS or more is required. Therefore, the change of the time supply source and the time of RKD are worse than the test of the self-excited paper wave standard, using the Chinese National Standard {CNS) A4 specification (210X 297 public money) --------- rape ------ '玎 ------ ^ «(Please read the notes on the back before filling in this page) -17- Printed by the Consumer Cooperatives of the Intellectual Property Office of the Ministry of Economic Affairs 4209 1 8 A7 ________B7 5 Explanation of the invention (^) 10 The stability time of the clock source is extremely effective. For example, when the time required for stabilization is 10 ms, the time difference above this can be effectively set. Also, only when switching to a self-excited clock source 'If you set different methods with different time differences, you can also effectively increase the system's operating speed. Also,' monitoring device 3 2 '3 3 control means 3 3 j, only the subscriber line interface 4 3, 5 3 ~ 5 3 'In case of failure of the subscriber line transmission system formed by 4 2, 5 2 to 5 2 of the network terminal, the alarm signal can still be output to the display device 3 6. Also, the display device 3 6 except the alarm light It can be turned on and off periodically in addition to lighting and turning off. By using a differential method using a plurality of warning lights, for example, it is possible to report the inside of the fault. Or failures other than obstacles of the subscriber line transmission system or extension transmission system. In addition, in the embodiment, for example, when the subscriber line transmission system fails, the subscriber line interface 34 is set to a non-signal state, and the extension transmission is performed. When the system is faulty, the subscriber line interface 3 4 can also be set to the state of signal synchronization loss. The switch 3 1 can detect these states of the subscriber line interface 3 4 so that it can identify that the failure occurred in the subscriber line transmission system. Or, the transmission system is extended. In this embodiment, the case where the loop monitoring system is used between the central office 3 and the subscribers' houses 4 and 5 has been described.

In the transmission path, the second monitoring device detects the occurrence of a failure on the terminal device side by the second monitoring device, and notifies the first monitoring device of the failure information indicating the failure. When the fault information is notified by the second monitoring device, the signal state output from the switch side becomes a no-signal state or a signal synchronization loss state, and the switch side can be notified of the occurrence of the above-mentioned fault. “Therefore, no conditions such as nib bit support are required” It is easier to monitor the status of the subscriber's home from the switch than the monitoring device. In the second item of the scope of the patent application, the extended transmission system includes a first monitoring device connected to the switch; a second monitoring device connected to the terminal device; and a connection between the first monitoring device and the second monitoring device. If the first monitoring device detects a failure of the extended transmission line or the second monitoring device, the signal state of the output switch may be changed to a no-signal state or a signal synchronization loss state. The above-mentioned failure notifies the switch side that “conditions such as support of nib bits are not required”, and the state of the home side of the subscriber including the second monitoring device can be monitored from the switch side. In the third item of the patent application park, the extension transmission is a multiple transmission of the signal of a plurality of subscribers, and the first monitoring device S connected to the switch side is referred to the complex of the switch.
