* Explanation of symbols for the main parts of the drawings

200: network subsystem (INS) 201: network synchronizer processor (NSP)

202: alarm access control unit (AACA) 210: central control subsystem (CCS)

211: operation maintenance processor (OMP) 212: alarm panel control unit (APCA)

The present invention relates to a switch having a maintenance processing function of a central control system (hereinafter referred to as a Central Control Subsystem (CCS)) and an interconnection network subsystem (hereinafter referred to as an INS (Interconnection Network Subsystem)). The present invention relates to an exchange for maintenance of CCS and INS.

The conventional exchanger was provided with a respective maintenance processing processor in the CCS and INS provided therein. That is, as shown in FIG. 1, the CCS 100 includes a central control maintenance processor 103 (hereinafter referred to as a Central Control Maintenace Processor (CCMP)) for maintenance. If the fault status is collected by the alarm access control unit 102 (hereinafter referred to as an alarm access control assembly (AACA)), the fault state collected by the AACA 102 in a predetermined time unit (about 200 msec) by loop back processing is performed. Is transmitted by the CCMP 103 to the FLM (Fault Management Block) not shown in the OMP 101 (operation maintenance process), and also to the alarm panel control unit 104 (hereinafter referred to as an Alarm Panel Control Assembly (APCA)). do. The OMP 101 transmits the fault status reported from the CCMP 103 to a terminal not shown so that an operator can recognize the ASMP 104, and the ASCA 104 displays an alert state to the operator. It transmits to the remote alarm panel unit (110, hereinafter called RAPU (Remote Alarm Panel Unit)) to display the fault status.

The INS 120 also has a network maintenance processor 130 (hereinafter referred to as INMP (Interconnection Network Maintence Subsystem)) for maintenance, and each device in the INS 120 (Network Synchronization (NES 121) as shown).

, TCDL (126, Trunk Central Data Link), HRC (127, High-Way Rate Conversion)

If the hardware failure status of the CDL (128, Central Data Link) and SSW (129, Space Switch, etc.) is collected in the AACA 125, the INMP 130 periodically loops back to the AACA 125. The collected fault condition is checked and transmitted to the FLM described above in the OMP 101. The OMP 101 transmits a fault state of the INS 120 transmitted from the INMP 130 to the terminal and the CCMP 103 not shown, so that the operator can recognize the OMP 101.

By providing a separate maintenance processing processor in the CCS and the INS, the management of the devices in the switching system is not only complicated, but also the number of IPCs (Inter-Processor Communication) increases the load of the switching system.

Accordingly, an object of the present invention is to provide an exchange having a function of processing maintenance of CCS and INS using one processor.

The apparatus according to the invention is characterized in that, in an exchange having a network subsystem (INS) and a central control subsystem (CCS), a failure state of the respective devices provided in the network subsystem and provided in the network subsystem and the central system are provided. An alarm access control unit (AACA) for collecting a failure state of a device provided in the control subsystem; A network synchronizer processor (NSP) provided in the network subsystem to check failure state information collected by the alarm access control unit; An operation maintenance processor provided in the central control subsystem, the operation maintenance processor having a function of receiving the checked failure status information from the network synchronizer processor and transmitting the received failure status information to the network synchronizer processor; And an alarm panel control unit (APCA) provided in the central control subsystem and controlled by the network synchronizer processor receiving the failure status information from the operation maintenance processor.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of an exchanger performing maintenance processing of the CCS and the INS using one processor according to the present invention, and a network performing the maintenance processing of the INS 200 and the CCS 210 as well as the network synchronizer maintenance. Synchronization processor 201 (hereinafter referred to as Network Synchronization Processor). AACA 202 collecting fault status for each device provided in INS 200 and CCS 210, devices provided in INS 200 as shown in FIG. 1 (INP 123). According to the data transmitted from the INS 200, OMP 211, and NSP 201, which are composed of NTP 124, TCDL 126, HRC 127, CDL 127, and SSW 129). CCS 210, which is composed of APCA 212 for controlling RAPU 110, which will be described later, RAPU 110, which displays an alarm status so that an operator can know, and operator terminal 220.

Here, the NSP 201 synchronizes the reference clock of the exchanger with the reference clock of the PASM synchronous digital switching network, and is composed of NSU (Network Synchronization Unit), which is a hardware unit, and Network Synchronization Management (NSM), which is a software unit. It is a network synchronizer maintenance processor of NES 121 which performs a distribution function. However, according to the present invention, the maintenance function of the INS 200 and the CCS 210 was further added. The present embodiment using the NSP 201 with the function added as described above operates as follows.

First, the AACA 202 provided in the INS 200 collects not only the fault status of each device provided in the INS 200 but also the fault status of the OMP 211 provided in the CCS 210. do. The fault status of the INS 200 and the OMP 211 collected as described above is checked by the NSP 201 for a change from the previous fault state by a loopback process. The check is made in a unit of time, where the unit of time is approximately 200 msec, as described above in FIG. If a change occurs due to such a change check, it is detected and the result is reported to the FLM not shown in the upper level block OMP 211.

The OMP 211 transmits the failure history reported to the FLM to the operator terminal 220 and transmits the information on the alarm signal to the NSP 201 so that the NSP 201 controls the APCA 212. Do it. Accordingly, the APCA 212 drives the RAPU 110 as before.

As described above, according to the present invention, the maintenance of CCS and INS in the exchange can be handled by using the NSP in the INS, so that the network management function and the maintenance function can be combined with software, so that the maintenance is easy. In addition, device management is easy at the system level, and the number of IPCs can be reduced to reduce the load on the system.
