Abstract
A system to enable communication between a base station controller (24) within a cellular network (12), and a wired telephone system (38, 39) in a wired subscriber loop (113), wherein the base station controller (24) is responsive to, and generates, cellular network signaling, and the wired telephone system is responsive to, and generates, wired signals. The system includes: a protocol processor (121) receptive to the wired signals, for generating processed signals; and a terminal adapter controller (34) conductively coupled both to the base station controller (24) and to the protocol processor (121), receptive to the processed signals, for generating cellular network signaling. In another feature of the invention, the cellular network signaling is GSM signaling. In another feature of the invention, the system also includes a voice service module (123) conductively coupled to the protocol processor, for compressing voice data to standard cellular compression. In another feature of the invention, the system also includes means (150) for converting mobility events in the wired telephone system to cellular network signaling.
