Patent GB-2435145-A (GB)
Title: Telecommunications line support system
Inventor: JACK IAN
IPC: H04M3/12
Filed: 2005-09-10
Abstract: In a microprocessor-controlled system that can decode Caller Line Identification (CLI) messages, one unit is installed in the customer premises and one in the telephone exchange using the CLI message to switch voice or data lines, or to report the status of the system. The lines may be fibre optic or any two-wire copper service. The unit may be connected to one CLI-enabled, standard telecommunications (POTS) line and also one or more alternative copper lines. In the event of a failure of one of the alternative copper services, the system remotely switches the POTS line in place of that alternative copper line. The POTS line acts as a substitute carrier until the alternative copper line is fixed. The alternative lines might be carrying any 2-wire copper service. The system remotely switches the POTS line in place of one of the alternative copper lines, so the POTS line test facility is now available for use on the alternative copper line. In one form, the unit is connected to one CLI-enabled POTS line and also one or more alternative fibre optic lines. In the event of a failure to one of the fibre optics, the system remotely switches to a spare fibre optic line. The spare fibre optic line acts as a substitute service until the original fibre is fixed. The system includes a time delay routine in the exchange software to operate the line-powered customer unit before the exchange unit. A dual current source and dual capacitors allow the drive electronics to be run at a higher voltage enabling a louder signal and speech, longer reach of phone line and the core electronics to be run at a lower voltage so that less power is used and lower current leakage losses occur when the circuit is actively processing data. One capacitor and power rail is switched off until full power is reached, facilitating a faster time to trickle charge from the line power.
