Disclosed are systems and methods for transferring data between servers and subscribers. A central office employs DSL circuit cards. Each DSL circuit card encodes a digital signal using a discreet multitone technology (DMT) scheme, and sends an encoded signal on a subscriber line. A disclosed architecture allows the functions of a faulty DSL circuit card to be assumed by another card, without substantial disruption of subscriber service. Further, the architecture allows the faulty DSL to be physically replaced, with minimal disruption of subscriber service. Another aspect of the architecture allows for the testing of subscriber lines.

A system and method for enhancing reliability in a communication system. In the system and method, redundant signal paths are continuously tested to determine if any faults are present while the operating signal paths are in use. If any faults are present in the redundant signal paths, they can be addressed while the operating circuits are still in use. This minimizes the chance that a switch from an operating signal path to a redundant signal path because of a fault in the operating circuit will result in downtime.
