ABSTRACT:
A repeater for use with Time Division Duplex (TDD) communications such as CT2 delivered over mains electricity cables. The repeater is coupled to a mains cable via a branch (the cable is not broken) and in alternate TDD phases converts signals from f.sub.1 .fwdarw.f.sub.2 or f.sub.2 .fwdarw.f.sub.1 and amplifies them. A clock signal to control timing of the conversion step is derived from a dedicated channel, a tone, or a call in progress. A regenerator function may be combined with the repeater.
