The TD-203/U is a 48- or 96-channel PCM radio transmission interface unit. The transmit section accepts TDM-PCM outputs from one or two TD-353/U's, or from one or two TD-204/U, or from another TD-203/U, and processes the outputs for radio transmission. The receive section accepts a PCM signal from a radio receiver, processes and retimes it, and extracts the orderwire signal.
