定パルスを入力しても、相手局の電源が投入されていな
い場合無意味であった。In a transmission line switching method that has multiple transmission lines and switches the transmission lines in response to a transmission line error alarm, input disconnection alarm, or out-of-synchronization alarm, switching to a specific transmission line when the power of the own station or another station is turned on. There is a need. If the power of the other station is not turned on when the power of your own station is turned on,
An input disconnection alarm for the own station is output, and information for selecting a particular transmission path cannot be obtained. In addition, even if the power of the other station is turned on, the error alarm, input disconnection alarm, or in-phase 1 error alarm of each transmission line disappears after the power of the own station is turned on.
It takes a long time for the transmission path to return to a normal state, and it is impossible to obtain transmission path switching information. -[- Even if we predicted the time when the transmission line would be in a normal state and then inputted the initial setting pulse, it would be meaningless if the partner station was not powered on.

Alternatively, a specific transmission path is set by the initial setting pulse 22 of the other station. In this case, the initial setting pulses 220 and 221 sent to the partner station are transmitted superimposed on the frame as sub information. In the initialization pulse circuits 213, 214, r? consists of a resistor 203, 207 and a capacitor 204, 208, respectively. If the time constant T of the C circuit is selected to be longer than the time required for the signal transmitting/receiving circuits 209 to 212 to reach a normal state from the time the power is turned on, the signal transmitting/receiving circuits 209 to 212 can go from a high level to a low level with a certain time constant when the power is turned on. The varying initialization pulses 220, 221 allow switching to a specific transmission path at power up. The transmission path can be set regardless of whether the power of the local station or the partner station is turned on first.
