Abstract
Abstract An hybrid network providing a range of services for subscribers, which services are separated by frequency allocation and include cordless telephony. The otherservices may comprise broadcast TV, premium TV, data, hi-fi etc. The network employs optical fibre (4) between a head end Cable TV (1) and telephony exchange (2) and intermediate distribution points (6) and coaxial cable (7, 9) from thence to the interior of the subscribers premises and a radio interface. Within the premises two-way cordless telephony operation is achieveable. A cordless telephony base station (11) can be provided at the intermediate distribution point (6) to provide outgoing call facilities for cordless telephones outside of the premises and within range thereof.
