Abstract

PURPOSE:To expand the electronic switching equipment being an object of monitor without increasing the installation of a control center by allowing the electronic switching equipment to return a reply message of a prescribed form in response to an incoming call from the control center. CONSTITUTION:A CPU 10 of a control center (OMC) 9 requests a call to a MODEM(M/D) 11 with an outgoing/incoming function so as to reach a telephone number assigned to a subscriber circuit (LC) 3 of the electronic switching equipment(EX) at a prescribed period. The M/D 11 dials and its call is reached to the LC 3 via a telephone network and a trunk circuit(TRK) 4. A central controller(CC) 7 of the EX 1 returns a reply message of prescribed form to the CPU 10 of the OMC 9 via a data transfer device (TC) 5, an M/D 6 and an LC 3. When the CPU 10 receives the replay message within a prescribed time, the CPU 10 discriminates the EX 1 to be normal and when no reply message is received even after a prescribed time elapses, it is outputted to an operation console device 12 to inform it to the maintenance personnel. Thus, the electronic switching equipment of the monitor object is expanded without increasing the installation of the control center.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a system for monitoring the operating status of electronic exchanges, and particularly to a system for monitoring the operating status of electronic exchanges in a maintenance operation system in which maintenance of multiple electronic exchanges is performed by one management center. Regarding the method.

[Conventional technology]

Conventionally, the operating status monitoring method for this type of electronic exchange has been to install a terminal for monitoring each electronic exchange in a management center, transfer the operating status signal from each electronic exchange to this terminal, and transmit it via the terminal's display. Either a maintenance worker at the center can grasp the status, or a processing device connected to this terminal can determine the operating status signal.

In addition, the maintenance personnel or the processing device sends commands to the exchange and receives detailed information.

[Problem to be solved by the invention]

As mentioned above, in the conventional electronic exchange operating status monitoring system, monitoring terminals are installed corresponding to each electronic exchange, so as the number of stations to be monitored increases, the number of terminals increases, making management difficult. The disadvantage is that a large floor space must be provided at the center.

[Means to solve the problem]

The operating state monitoring method for electronic exchanges according to the present invention is a maintenance operation system in which a plurality of electronic exchanges are maintained by one management center, wherein the management center has call originating means for sequentially generating incoming calls to each of the electronic exchanges. and receiving means for receiving and analyzing a response message in a fixed format that is returned in response to the incoming call, and the electronic switching equipment returns the response message in the fixed format in response to the incoming call from the management center. and response means.

With the above configuration, the present invention shown in FIG. 1 will be described in detail. 0MC9's CPU10 requests the M/Dll to make a call to the telephone number assigned to EXl's LC3 at regular intervals. The M/D 11 automatically dials the telephone number received from the CPU 10 after making a call. This call arrives at LC3 via the telephone network and TRK4. Upon receiving this call, CC7 of EX1 returns a response message in a fixed format to CPU10 of OMC9 via TC5, M/D6, and LC3. This response message is sent to the CPU
If EX1 is received within a certain period of time, CPU10 determines that EX1 is normal, and if no response message is received after a certain period of time, it outputs this to WSi2 and notifies the maintenance person.

The above operation is performed similarly for other electronic exchanges.

〔Effect of the invention〕

As explained above, the present invention has the effect of increasing the number of electronic exchanges to be monitored without increasing the equipment of the management center.
