Detection of failures in signal transmitting/receiving devices has been conventionally performed, and FIG. 1 is an explanatory block diagram thereof. In the figure, NWO and NWI are communication paths, OGT 1 to OGT o are outgoing trunks, and ICT 1

あると言う欠点があつた。 However, in this case, even if the selection signal receiving device IRi detects the occurrence of a failure by detecting an abnormality in the code of the selection signal, the cause of the abnormality in the code of the selection signal is the selection signal transmission. Failure of device OSi, selected signal receiving device IRi
Because there are various types of failures, such as failures in the selection signal transmitter OSi and combinations of a specific selection signal transmitter OSi and the selection signal receiver, it is difficult to identify the cause of the failure detected by the selection signal receiver IRi. There was a drawback that early detection of the selection signal transmitting device and the selection signal receiving device was difficult.

るものである。 Detection of a failure in the selection signal sending devices OS 1 to OS n and the selection signal receiving devices IRO 1 to IRO k is performed by controlling the communication path NWO by the connection control device OSIRC and connecting any selection signal sending device OSi and the selection signal receiving device. This is done by sequentially connecting the IROi via the call route PHT and having the O station execute the selection signal reception operation, and by this selection signal transmission and reception operation, a specific selection signal sending device and a plurality of selection signal receiving devices If an abnormality in the code code of the selection signal is detected in combination with If an abnormality is detected, the selected signal receiving device is determined to be at fault.

と判定するものである。 Furthermore, the failure history of the selection signal receiving devices IRO 1 to IRO k and IR 1 to IR l in the selection signal transmission/reception operation between stations is stored, and the selection signal receiving device that continuously detects a failure is stored. By determining that there is a failure, it becomes possible to easily detect a selection signal receiving device in which a failure has occurred even during normal call connection operations between stations. For example, selection signal sending device
OSi - Call route PHO - Outgoing line trunk OGTi - Interoffice line TKLi - Incoming line trunk ICTi - Call route
When a PHI-selection signal receiving device IRi train is formed, if the selection signal receiving device IRi detects a fault by detecting an abnormality in the code pattern of the selection signal, for example, (not shown)
After this, when a train including the selection signal receiving device IRi is formed again, the selection signal receiving device IRi detects a failure by detecting an abnormality in the code pattern of the selection signal. In other words, if the selection signal receiving device IRi continuously detects a fault, the selection signal receiving device IRi is determined to be faulty.

論である。 In the embodiment, the selection signal transmitting device and the selection signal receiving device are sequentially connected within the own station to perform the selection signal transmission and reception operation, and the failure history of the selection signal transmitting and receiving device is stored to prevent failures. However, even if only one of them is performed, it is of course easier to identify the faulty device compared to the conventional selection signal transmitting/receiving device fault detection method.

利点がある。 As explained above, the present invention connects the selection signal transmitting device and the selection signal receiving device of an exchange in sequence within its own station to perform the selection signal transmission/reception operation. Since a fault in the selection signal transmitting/receiving device is detected by a combination of a specific selection signal receiving device or a combination of a specific selection signal receiving device and a plurality of selection signal transmitting devices, the location of the fault can be easily identified. This has the advantage that a faulty selection signal transmitting/receiving device can be detected early.
