Abstract: The system comprises a multiple outlet terminal (100), individual connection modules (200), and independent out-stations (300). The terminal (100) is connected to a plurality of telecommunications lines (102) and comprises line interface means, a plurality of individual outlets (104), and distributor means. Each module (200) can be separably mounted on any one of the outlets and comprises means for interfacing with the distributor means of the terminal, wireless transceiver means, and control means suitable for converting the signals coming from a line and delivered by the terminal into radio signals, and for converting received radio signals into signals for delivering to the same line. Each out-station (300) comprises wireless transceiver means suitable for establishing a both-way communications channel, and means for interfacing with transducers (310, 312, 314) for picking up and/or playing back audio, video, and/or digital data signals.
