摘要： A method of operating an access network including a plurality of data connections (19) between end-user devices (12, 14, 16, 18) and an aggregation transceiver device (20) at which the connections (19) are aggregated for onward connection through the access network, the method comprising storing a plurality of different profiles, each profile specifying values for parameters associated with each connection (19); and, for each connection, obtaining connection data relating to a monitoring period, said monitoring period comprising a plurality of shorter periods, said connection data comprising, for each of said shorter periods, an indication of whether said connection has experienced instability during said shorter period, and an indication of user activity on said connection during said shorter period; monitoring the performance of the connection in dependence on said connection data; selecting one of said stored profiles to be applied to the connection in dependence on the results of said monitoring; and applying the selected profile to the connection.

摘要： A system for and a method of providing a telephony service is disclosed. Supplying power to a node in a telecommunications network from a subscriber's premises conflicts with the plain old telephone service POTS. Until the advent of the present invention it was thought that supplying power in this way required either an additional electrical transmission wire or providing voice support within a digital subscriber line (DSL) service. In the proposed system telephony control signals, as supplied by an exchange (103) on to a first section (107) of an electrical transmission line, are converted into modified downstream control signals having a different frequency to electrical power, which is supplied onto a second section (109) of the electrical transmission line, and electrical equipment in a node that interconnects the first and second sections can draw electrical power supplied by the power supply without affecting the operation of a telephone (101).
