Abstract

PURPOSE:To attain the accurate administration of a communication equipment by transmitting a return confirmation signal to a specified communication equipment when a bit of simultaneous multiple address information is not received from the specified communication equipment for a regulated period, and deciding a state based on a response state. CONSTITUTION:Each bit of simultaneous multiple address information at every thirty seconds lapse from all of other communication equipments 1b-1n is written on each corresponding area of memory areas 15b-15n within a memory device 15. When the content of the memory 15b is good as a result by checking, a corresponding counter 16b is set initially, then its value being set as '9' and when it is bad, the value of the counter 16b is set as '-1'. When the value becomes '1', since it means that a bit of administration information has not received continuously for eight number of times and for the first time, a transmission part 17 is started up, and at the communication equipment 1b to which an echo signal is sent, when it is operated normally, the transmission part 17 is started up, and an echo response signal is returned to a communication equipment 1a, and when it is in a down state, the echo response signal is not returned.

FIG. 4 is a flowchart when the reception management information received in this way is checked. For example, the communication device 1a checks the contents of the memory area 15b in the memory device 15 (reception management information based on a broadcast notification from the communication device 1b). This is for checking. As a result of checking the contents of the corresponding memory 15b (step 41), if reception management information exists, it is determined that the memory contents are good; however, if it is determined that no reception management information has been received (that is, reception management information has not been received), then ( step 42),
The value of the corresponding counter 16b of the monitoring counter 16 is set to -1 (step 43). It is assumed that the initial set value of the counter is 9, for example. This counter 1
If the value of 6b is not 1 (step 44), the reception management information will be checked by the next simultaneous broadcast notification (step 45, 4.1).

If the result of checking the contents of the memory 15b is good (step 42), the corresponding counter 16b is initialized to a value of 9 (step 48). On the other hand, if the value of the counter 16b becomes 1 (step 44), it means that the management information from the communication device 1b has not been received eight times in a row, so the transmitter 17 is activated for the first time and the echo signal is transmitted. It is sent to the device 11Flb (step 46).

If the communication device 1a is not operating normally and is in a down state, this echo response signal will not be sent back, so the reception of this echo response signal is determined on the communication device 1a side (step 47). As a result, if the echo response signal is not received, it is determined that the communication device 1b is down (step 49), and if the echo response signal is received, the counter 15b is initialized to 1 (step /I).

In this way, only when the reception management information from a specific communication device is not received 8 times in a row (this number (1f1 is not limited, multiple times is enough)) is sent to this specific communication device. Since it is determined that the communication device is down only when an echo signal is sent out and no echo response signal is received in response to the echo signal, accurate determination can be made.
