Systems and methods for integrating a telephone internal access return link with an upstream data carrier using a fiber optic network (13) and downstream data transfer using a cable TV system (20). The systems and methods provide for a cost effective implementation of a data over cable TV system using the cable system for downstream data transfer and a telephone modem for upstream data transfer. The telephone return path is terminated at a neighborhood node or optical network interface (12) of the cable TV system. The optical network interface (12) combines, modulates, and multiplexes the upstream data onto an upstream fiber carrier. At the cable headend (11), the carrier is demultiplexed, demodulated, and the data is forwarded to a remote access server (40) of an Internet service provider. |
