The application of multiplexed PCM channels to a microwave radio system is attractive in areas where geographic terrain limits the practicality of cable plant construction. A technique of interfacing the digital signal with an analog radio baseband is described. The successful Inclusion of a voice-frequency (VF) orderwire at the low frequency end of the digital spectrum without a significant penalty in error-rate performance demonstrates the efficiency of the technique.
