Having passed through the linear decoding unit (BLDK) ) 33, the group digital stream is supplied to the electronic key (EC FL / RK) 32, for manually alternately connecting the group digital stream to the wired physical line or radio relay channel, and then to the receiver synchronization and control unit (BSUSh) 25 and the digital channel demultiplexer unit in (BDMTSK) 31, which extracts information from the group digital path corresponding to this digital stream.
