Abstract
A Unified Access Platform capable of providing telephone and high speed data services in a number of different local loop configurations. In a first embodiment, a broadband digital terminal (BDT receives high speed data and telephony signals, and combines them into a cell based signal which is transported to an access multiplexor. At the access multiplexor, a first linecard generates an analog telephone signal, and a second linecard generates a high-speed data signal. Analog telephone service is provided over a first twisted wire pair drop cable, while the high speed data service is provided over a second twisted wire pair drop cable. In an alternate embodiment, the BDT's cell based signal is transported to two separate terminals. Analog telephone service is provided to a subscriber location from the first terminal, while high speed data service is provided to a second subscriber location from the second terminal. Yet another embodiment provides analog telephone and high speed data services from a single linecard located in an access multiplexor. The analog telephone and high speed data signals are generated on the linecard and combined using a diplexor. At the residence, a receivi…
