Abstract

PURPOSE: To attain effective utilization of a radio wave by providing coding/decoding circuits of plural kinds provided at each plural service kinds of a public communication network and a synthesis circuit connecting the input/output of a radio transmitter- receiver with the plural kinds of coding/decoding circuits as a connection means between a radio transmitter and a public communication network.
CONSTITUTION: In an equipment of a base station, a connection device 13 is connected to a telephone communication network 11 being a public communication network and a digital communication network 12. The connecting device 13 connects to coding/ decoding circuits 14∼17 different from the service kind and the coder side terminal is connected to the synthesis circuit 18. The serial signal side terminal of the synthesis circuit 18 is connected to a transmitter-receiver circuit 19. A radio wave is sent in a radio frequency assigned from the transmission/reception circuit 19. Then the coder/ decoder circuits 14∼17 having a different function corresponding to the different service class such as telephone(DP, PB, digital), facsimile(G2, G3), telex and data communication are provided. The signal from the coder/decoder circuits 14∼17 is a parallel signal, the synthesis circuit 18 converts it into a serial signal and gives the signal to the transmission/reception circuit 19.
