Abstract: In a terminal connected to a distribution cable composed of wire pairs corresponding to communication lines, the wire pairs are disposed in an array across index strips. Termination of a selected wire pair corresponding to a communication line is achieved by mounting an insulation displacement connection (IDC) connector on one of the index strips. In the mounting process, the connector makes electrical contact with the selected wire pair. Drop wires may then be connected to the IDC connector, and brought into customer premises to realize the communication line. Unterminated wire pairs are available for termination at another terminal. Advantageously, using one or more terminals to distribute the wire pairs in accordance with the invention obviates, among others, the need for a prior art feeder distribution interface used in the traditional wire pair distribution.
