System and method for reliably communicating telecommunication information

A system for reliably communicating content for multiple subscriber lines of a customer location via a single physical transmission medium, the system comprising:

• a telecommunication interface that receives content for first and second subscriber lines of the customer location;
• a processing core, in communication with the telecommunication interface, that converts the content for the first and second subscriber lines into packetized data for network communications;
• an added-main-line (AML) concentrator, in communication with the telecommunication interface, that multiplexes the content for the first and second subscriber lines to form an AML signal that includes power;
• and
• a signal splitter, in communication with the processing core, the AML concentrator, and the single physical transmission medium, the signal splitter operable to communicate the packetized data between the processing core and the customer location via the single physical transmission medium in a primary mode of operation and to communicate the AML signal between the AML concentrator and the customer location via the single physical transmission medium in a backup mode of operation, such that external power can be used at the customer location to extract the content for the first and second subscriber lines from the packetized data in the primary mode of operation, and the power from the AML signal can be used at the customer location to extract the content for the first and second subscriber lines from the AML signal in the backup mode of operation.
