Abstract
An arrangement for generating and receiving standard telecommunications network signals on behalf of a terminal not equipped to generate or receive such signals. A controller shared by a plurality of such terminals receives signals from these terminals over a permanent virtual circuit (PVC) and uses the information received over the PVC to perform signaling. In a specific embodiment, the terminals are set top boxes, connected to a video cable, for controlling television sets. The controller controls signaling for establishing connections between the set top box and a video vendor system, and tunes the set top box to receive signals on the proper channel. Advantageously, such an arrangement significantly reduces the cost of the set top box while still allowing for a highly flexible signaling arrangement to the video vendor system.
