Abstract
A digital subscriber line (DSL) unit comprises a first user port configured to communicate signals according to an Ethernet protocol and a second user port configured to communicate signals according to a second non-Ethernet protocol The DSL unit also comprises at least one DSL port configured to communicate signals according to a DSL protocol; and a processing device configured to analyze Ethernet signals received over the first user port to determine when to output data from the respective received Ethernet signals over the second user port and when to output data from the respective received Ethernet signals over the at least one DSL port. The processing device is further configured to extract data from signals received over the second user port and insert the extracted data into a corresponding Ethernet signal having a respective emulated circuit identification and to output the corresponding Ethernet signal over the first user port.
