ABSTRACT:
Each of a terminal adapter and a switching equipment ancillary device has a protocol controller for analyzing and controlling a communication protocol control signal transmitted from a data terminal, so that a modem interface can directly be set to an originate mode or an answer mode. As a mobile station has no modem function, the switching equipment ancillary device and a modem terminal are synchronized with each other by a clock signal, and transmit and receive data therebetween. A transmission delay caused by a retransmission effected under error correction control on a communication line is adjusted by flow control between the modem interface and the modem terminal.
