Abstract

A technique for reducing or eliminating the access charges typically payable by an IXC to a LEC, and, in turn, payable by the subscriber to the IXC, for originating long distance calls by providing a hardwire connection between the IXC and the customer premises. The hardwire connection is created by purchasing analog facilities from the LEC which originate at the Central Office and connecting these facilities directly to a Central Office D4 multiplexer. The terminating end of the analog facilities are installed at the subscriber premises and terminated on a standard RJ11X four wire jack. The voice interface modules typically used in the D4 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. A T1 or higher capacity digital facility is also ordered from the LEC to terminate to the Central Office D4 multiplexer, and the T1 or higher capacity digital facility is D4/AMI configured for 56 kbps DS0 channels. The terminating end of the T1 or higher capacity digital facility is directed to a tandem 'toll' Central Office and is terminated on a K01 digital electronic cross-connect system (DEXCS) frame which is ordered from the LEC. Each of the channels of the T1 or higher capacity digital facility is then configured by the customer using a network reconfiguration service at the end pointing towards the Central Office D4 multiplexer with Foreign Exchange Office (FXO) Loop Start signaling. A T1 is also ordered from the LEC to connect the DEXCS to the IXC and is also D4/AMI configured for 56 kbps DS0 channels. Each of the channels of this T1 is also configured by the customer using the reconfiguration service at the end pointing towards the IXC with FXS Loop Start signaling. The IXC terminates the T1 from the DEXCS within its own Call Control Platform.
