PURPOSE:To improve the efficiency of communication by inputting carrier transmission completion information to a time slot coupling between a circuit corresponding part connecting a circuit including a MODEM and a circuit corresponding part directly connected to a terminal. CONSTITUTION:A frame consisting of a frame head and plural time slots is made to flow into a corresponding part LSa on the MODEM3 side and a corresponding part LSb on the terminal 1-2 side and each time slot corresponds to a node. Each time slot includes carrier information RSCD and carrier transmission completion information CS together with data. At the start of communication, the terminal outputs a carrier sending request signal to the corresponding part LSb, a communication system detects the signal and transmits the detected signal to the corresponding part LSa as the carrier information RSCD to turn on the RS terminal of the MODEM. Consequently, the corresponding part LSa is immediately transmitted to the corresponding part LSb as the carrier transmission completing information CS. |
