ABSTRACT:
A device for use in an intermediate station of a radio-relay communications system comprises a package consisting of a trunk switch, a multiplexer, and a demultiplexer. The switch (48) has three TDM inputs, one of which is connected to the output of the multiplexer, and three TDM outputs one of which is connected to the input of the demultiplexer. The switch is non-blocking and is adapted to switch any input TDM channel to any selected output TDM channel, to enable, for example, a signal received in an incoming channel from an adjacent radio station to be selectively retransmitted to radio station or directed to one of the user terminals at the radio station.
