Thus, the time division multiplexed signals, including clocks, are generated. In reception mode, the clocks are extracted and the base-band signals are restored synchronously with extraction of clocks. In this way, the data can be easily received a time division multiplex way. This system is applied to a cellular phone communication system. A transceiver 10 and a modem 20 of a cellular phone 5 are provided on a city power opening/closing control line 25. Furthermore, a DSU 50 and a modem 20 are placed immediately prior to an ISDN exchange 60.
