A Unified Access Platform (UAP) 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 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 phone 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, a broadband digital terminal's cell based signal is transported to two separate terminals. Analog telephone service is provided to a subscriber location over from the first terminal, while high speed data services are provided to a second subscriber location from the second terminal. Yet another embodiment provides analog telephone and high speed data services from a signal 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 receiving diplexor is used to separate the analog telephone and high speed data signals. Still another embodiment generates a high speed data signal at an access multiplexor which contains a digital representation of the analog telephone signal. The high speed data signal is sent from the access multiplexor to the residence, where a receiving device generates an analog telephony signal and transmits the high speed data signal to the appropriate terminal equipment. |
