ABSTRACT:
An optical fibre communications system includes an exchange (E) and a plurality of subscriber lines (1). The exchange (E) provides a plurality of services in different subcarrier frequencies (6,8,9,10). Each subscriber line (1) is provided with terminal apparatus (5) operable at different subscriber frequencies, and a control (11) at the exchange (E) tunes the terminal apparatus to transmit and/or receive on a particular frequency in response to a request. The request may be a signal from the terminal apparatus (5), or an incoming service request addressed to the particular terminal apparatus.
