Abstract

A return path (150) may include a modem pair (140) that is coupled to existing electrical waveguides in a structure such as a house or office building. Specifically, a first modem of the modem pair may be coupled to a first end of a coaxial cable and to a video service terminal (115). A second modem of the modem pair may be coupled to a second end of the coaxial cable and a data interface (608). The first modem can modulate video control return packets onto an RF carrier that is propagated over the coaxial cable to the second modem. The video control return packets can be formatted as Ethernet type packets. The second modem can demodulate the RF carrier to extract the video control return packets and to forward these packets towards a data service hub.
