ABSTRACT:
A technique for bypassing a local exchange carrier ("LEC") so as to reduce or eliminate the access charges typically payable by an interexchange carrier ("IXC") to a LEC, and, in turn, payable by the subscriber to the IXC, for originating long distance calls. A hardwire connection is provided between the IXC and/or a Central Office operated independent of the LEC and the customer premises by purchasing analog facilities from the LEC which originate at the Central Office and connecting these facilities directly to a multiplexer. The terminating end of the analog facilities are installed at the subscriber premises. The voice interface modules typically used in the multiplexer are replaced by Foreign Exchange Subscriber (FXS) modules which perform A/D conversion of the analog voice data provided over the analog facilities from the customer premises. The terminating end of a T1 or higher capacity digital facility is terminated on the multiplexer and on a K01 digital electronic cross-connect system (DEXCS) frame at the LEC Central Office. A T1 is also ordered from the LEC to connect the DEXCS either directly to the IXC or to the independent Central Office. Each of the channels of the T1 lines are configured by the customer using a network reconfiguration service with FXS Loop Start signaling.
