Abstract

A TDM/TDMA (Time Division Multiplex/Time Division Multiple Access) multidirection multiplex communication system of the type using a demand assignment protocol. The system has a multiframe arrangement in which each unit frame is constituted by a frame synchronization signal, a connection control signal for setting up radio channels, N conversation channels, and a single additional bit transmission channel shared by the N
conversation channels. When N unit frames are combined in a multiframe format by a frame synchronization signal, N
additional bit transmission channels are provided in total.
