Abstract: A system and method that uses the flexible bandwidth of a data network in order to provide more flexible services to remote line units comprises a telephone switch configured to provide telephony service to a wireline terminal and an access network head end connected via circuit switch transmission facilities to the telephone switch and configured to manage bearer channels in a data network. The system also includes a data network carrying the bearer channels and a.line unit separate from the telephone switch connected to the data network and to the wireline terminals configured to interface wireline terminals to one of the bearer channels. The access network head end reserves a predetermined bandwidth through the network and allocates a portion of the bandwidth to each of the line units. The amount of bandwidth allocated to each line unit is variable.

Abstract: An improved plain old telephone service (POTS) line card that may be direct ly connected to a customer line that is also connected to a digital subscriber line access module. A second order filter is added to the front end of the POTS line car d in order to attenuate XDSL signals and to lower its amplitude. A new digital signal processor (DSP) includes further low pass filtering functions, gain compensation, termination impedance compensation and balance network compensation to provide the prope r balanced network as is known in current POTS cards but not provided in curre nt XDSL services. This card may also be used alone, without a XDSL equipped lin e.

Abstract: The present invention provides a cellular communication system that includes a central radio pool/traffic router (CRP/TR) that sends control and traffic signals over fiber optic transmission links that connect the CRP/TR with base stations of the cellular communication system. The high bandwidth capacity of each fiber link allows a large band of radio frequencies representing many radio channels to pass between t he CRP/TR and individual base stations. Radio resources can be shared by all base stations in the cellular communication system, dynamically, when and where needed, to meet access demands throughout the system. The CRP/TR includes low-powered digital and/or analog radios and also switching and modulation means used to convey signals betwee n the radios and various base stations within the system.

Abstract: The remote subscriber line unit provisioning system which operates on a shared facilities basis with the voice communication facilities of the remot e subscriber line unit. This architecture eliminates the need for dedicated communication facilities to interconnect the remote subscriber line unit wit h the central facilities management system.
