ABSTRACT:
There is disclosed a communication system in which a line switch signal is sent to a remote station side from a local station side to switch a line without deteriorating the transmission efficiency. A CC message encoder allots the unused bit of CC message to a line switch signal for requesting line switch to a line switch circuit. DCME inserts CC message into a predetermined position in a DCME frame during a multiplex processing. DCME extracts CC message from the received DCME frame. A CC message decoder extracts the line switch signal included in the CC message. The line switch circuit connects one of a plurality of lines in response to the line switch signal.
