Abstract
The present invention provides an effective way for Telecom operators to provide ADSL service to customers who are receiving POTS service over a pair gain system or who are connected to ISDN. According to one embodiment of the invention, an ADSLNDSL (Very High Speed DSL) splitter is integrated in the remote terminal of a pair gain system or in the NT1 (Network Termination 1) of an ISDN BA (Basic Access). Therefore, no extra box on the house and no extra truck roll is required when the customer orders ADSL service. Integrating the splitter makes the telephone line upwards compatible with UADSL since UADSL can be directly connected to an analog telephone line. According to another embodiment of the invention, both the splitter and ADSUUADSL modems are integrated in the remote terminal of a pair gain system or in the NT 1 of an ISDN BA. The splitter in the telephone company location may also be integrated in the central office terminal (COT) of the pair gain system. According to a further embodiment of the invention, the UADSL signal output of an ADSL splitter in the remote terminal of a pair gain system is connected to an analog POTS port, with appropriate filtering. According to this embodiment, the UADSL signal is connected to all POTS lines coming out of a remote terminal. Connecting the UADSL output of the splitter to the POTS output eliminates the need for additional wiring in the customers house.
