Abstract (en)
[origin: GB2313273A] Telecommunications signals are carried on a cable 111 which carries mains electricity to a consumer's premises. A network conditioning unit NCU and a subscriber's interface unit SIU are provided between the mains cable 111 and conventional subscriber's terminal equipment (25A, 25B, 25C) adapted for full duplex communication with a local telephone exchange. The subscriber's interface unit SIU converts telecommunications signals between this duplex form (typically analogue at audio frequencies) and time division duplex (TDD) form at a carrier frequency in the range 1 MHz to 20MHz for coupling to the mains cable 111. In the example, TDD interface means 40 provides cordless telephony digital standard formatting/deformatting and modulating/demodulating at a carrier in the band 864MHz to 868MHz, and a frequency converter 50 converts between this band and, typically, 2MHz to 6MHz.
