Abstract

A system for communicating telecommunication information includes a memory, packetization modules, and a telecommunication interface module. The memory stores subscriber profiles associating each of several subscribers with a telecommunication interface. The packetization modules receive data packets from a broadband network and extract telecommunication information associated with a subscriber from the data packets. The telecommunication interface module communicates the telecommunication information to a telecommunication network using a telecommunication interface associated with the subscriber.
