Local network for managed telephone handsets includes base station receiving radio broadcasts and relaying these to local handsets

摘要

The system combines telephone facility with radio reception. The local telephone network comprises telephone handsets (2) and a handset management base (1). The base includes circuits (15) for reception of transmitted radio programmes, and further circuits (11, 14, 16,17) for the transmission of these programmes to the handsets via the local network. A data table is held within the management base in which the reception frequencies are recorded, and this is used in their reception. The base station is also able to operate according to a programmed calendar in order to pick up selected broadcasts, and is able to send radio signals to the local handsets in order to control their local amplification. The power supply cable to the base station may serve as the aerial for its radio communications.
