POWER DISTRIBUTION FOR TELECOMMUNICATIONS SYSTEM

摘要

A communications connection comprises intermediate connection points (6,11) connected by a non-conducting communications link (20), with conversion equipment in one or both intermediate points for converting communications between electrical and non-electrical carriers, and each being arranged to be powered from the respective ends (1, 12). If a metallic path (18) is present between the two intermediate points, the system can be arranged to use this for a limited connection service in the event of loss of electrical power to one or both of the intermediate points (6,11).

主权项

1. A communications connection comprising a first intermediate connection point, a second intermediate connection point, and a non-conducting communications link between the first intermediate point and the second intermediate point;
the first intermediate connection point being connectable by way of a first conducting link to a telephone network connection point and the second intermediate point being connectable by a plurality of second conducting links to a plurality of remote customer premises installations, at least one of the first and second intermediate points having conversion equipment for converting transmissions between electrical signals carried over its respective conducting link, and a non-electrical signal carried over the non-conducting link the respective first and second conversion equipments being electrically powered, and having respective power conversion equipment for receiving electrical power delivered over the respective conducting links from the telephone network connection point and the customer premises installations.
