Abstract:
1. A method for reliably communicating content for multiple subscriber lines via a single physical transmission medium between a telecommunication gateway and equipment at a customer location, the method comprising: receiving content for first and second subscriber lines of the customer location; converting the content for the first and second subscriber lines into packetized data and communicating the packetized data between the customer location and the telecommunication gateway via the single physical transmission medium in a primary 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 multiplexing the content for the first and second subscriber lines to form an added-main-line (AML) signal that includes power and communicating the AML signal between the customer location and the telecommunication gateway via the single physical transmission medium in a backup mode of operation, such that 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.
