Abstract:
A bidirectional broadband and telephony network controllable from the exchange end 15. An optical fibre 16 carries the services to customers premises 30, 31 via passive optical splitters 17, 18. Telephony from block 10 is provided on one wavelength, broadcast TV from block 11 on a second wavelength an bidirectional asynchronous time division information from block 40 on another wavelength using ATD (Asynchronous Time Division) 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.
