Abstract
A communication system and method for supporting both POTS and high speed data services between a remote CPE interface, located at a subscriber premises, and a central office. An analog to digital converter transforms an analog POTS signal to a digital POTS signal, and a combiner circuit combines the digital POTS signal with a high speed data signal into a combined digital signal which preferably has a single communication spectrum. A power detector identifies a power failure at the remote CPE interface, and a life line communication path is established from the central office to the remote CPE interface in response to the power failure.
