ABSTRACT:
A switching system (14) at a customer premises communicates information associated with one or more subscribers. The switching system (14) includes multiple subscriber line ports (17) for communicating xDSL signals with subscribers, the xDSL signals containing both data signals and POTS voice signals. A logical port (20) communicates data signals and packetized voice signals from the subscribers with a central office, the switching system (14) converting between the POTS voice signals of the subscriber lines (16) and the packetized voice signals of the logical port (20). A LAN port (21) communicates data signals with a server complex (23) using a LAN (22) to provide data services to the subscribers. The switching system (14) may include a switch (32) that receives voice signals on a first virtual circuit (VC), switches the voice signals out of the switching system (14) on the first VC, and also communicates received data signals for routing. A router (32) within the switching system (14) may receive the data signals from the switch (32) on a second VC, determine a third VC for the data signals, and route the data signals to the switch (32) on the third VC for communication out of the switching system (14) on the third VC.
