故障診断を行う装置内監視方式が重要となる。[Prior Art] In general communication devices such as transmission devices,
When a device in operation breaks down, resulting in a line failure, there is an especially strong need for quick failure recovery. Systematic measures such as redundant circuits and pilot monitoring have been taken to deal with line failures, but for complete failure recovery, it is important to first identify the failure location. For this reason, an in-device monitoring system in which the device itself performs its own failure diagnosis is important.

行う監視回路は単位回路毎に設けられていた。[0003] Conventionally, as an internal monitoring method of this type, a path pattern is inserted into empty bits of input data for each unit circuit of a panel to be monitored or a collection of panels, etc.
This was extracted from the data on the output side, and the failure was diagnosed by checking for errors, and if there was an error, further protection was performed and then an alarm was output. A monitoring circuit that performs this series of operations is provided for each unit circuit.

。[Problems to be Solved by the Invention] As mentioned above, the conventional internal monitoring circuit requires a monitoring circuit for each unit circuit to be monitored, and as the number of unit circuits to be monitored increases, the number of monitoring circuits increases by the number of unit circuits to be monitored. This has the drawback of increasing the circuit scale.

The input data to the circuit to be monitored 4 is, for example, a frame-structured multiplexed signal in which a path pattern is inserted for each data. This path pattern is usually an arbitrary pattern of 4 to 8 bits and is inserted using empty bits.

The output data enters the selection circuit main body 11, output data 1 to n are sequentially selected, and the path pattern inserted therein is extracted. The extracted path pattern is multiplexed n times for each frame of data and is output to the next error detection circuit 2.

When the alarm circuit 3 receives an error signal at the time of non-coincidence, it performs confirmation judgment, that is, protection, and then outputs an alarm for each circuit to be monitored.
