Abstract
A method reliably communicates content for multiple subscriber lines via a single physical transmission medium between a telecommunication gateway and equipment at a customer location. In that method, content for two or more subscriber lines of the customer location is received and converted into packetized data for network communications and/or multiplexed to form an added-main-line (AML) signal that includes power. The packetized data or the AML signal is communicated between the customer location and the telecommunication gateway via the single physical transmission medium. External power can be used to extract the content for the two or more subscriber lines from the packetized data in a primary mode of operation, and the power from the AML signal can be used to extract the content for the two or more subscriber lines from the AML signal in a backup mode of operation.
