に対する発呼処理を終了する。On the other hand, when a predetermined period of time has elapsed since the transmission of the incoming telephone number, the control circuit 8 in the subscriber line control device sends a circuit scanning signal written in a corresponding storage area in the pseudo call control memory 9. The caller is disconnected by inverting from "0" to "1". The common control device, which receives the caller disconnection notification via the line scanning signal line 6, ends the call processing for that subscriber.

の動作が繰り返される。After a predetermined period of time has elapsed, the control circuit 8 generates a pseudo call again by inverting the line scanning signal in the pseudo call control memory 9 from "1" to "O". This pseudo call causes the above-described operation to be repeated between the line control device and the common control device.

“Ｏ”から“１”に反転されるまで繰り返される。When such a pseudo call occurs, a command to restore normal processing is issued from the common control device to the control circuit 8 via the control link 7, and after the pseudo call occurs, the processing command flag in the call control memory 9 is set to "O". This is repeated until it is inverted to "1".
