The unit includes a radiotelephone terminal which is complementary to the portable radiotelephone terminal, preferably remains in place, and can be used conjointly with the portable radiotelephone terminal when connected to the relay transceiver station by a call set up via the station. Complementary functions of the two terminals can be employed by the same user having simultaneous access to both terminals.
