Method and apparatus for out-of-band XDSL troubleshooting and testing
In one illustrative embodiment a system for maintaining a communication link over a network includes a processor adapted to be coupled to a first communication link, the first communication link connected to a customer premises equipment (CPE), wherein the processor transmits data over the first link and switches to transmit data over the second link in response to a signal that is indicative of a degradation of service over the first link. In one aspect the system may include a switch at a service provider Digital Subscriber Line Access Multiplexer (DSLAM) for switching to a spare pair communication link when a degradation of service signal is received. In another aspect at least one spare pair communication link may be associated with a plurality of primary communication pairs.
