Abstract
A bidirectional broadband and telephony network is controllable from an exchange or head end of the network. An optical fiber (16 ) carries the telephone services to customers' premises (30, 31) via passive optical splitters (17, 18). Telephony is provided on one wavelength, broadcast TV on a second wavelength, and bidirectional asynchronous time division information on another wavelength using ATD techniques. Time-slots are allocated for information packets so they can travel without interference to and from receiving stations and the round trip delay between stations is adjusted to achieve this whilst maintaining minimum bandwidth requirements. Dynamic allocation of spare capacity is provided for bursty services.
