1. An interface test assembly for use in a telephone communication network including an incoming central office cable and outgoing customer telephone lines comprising:

  • a housing;

    the housing including at least one terminal block assembly having at least one telephone line interconnect element for selectively interconnecting the incoming central office cable to at least one of the outgoing customer telephone lines;

    a normally inactive receptacle element fixedly mounted in the housing and coupled to a plug member;

    the plug member is positioned adjacent the terminal block assembly in the housing and is structured and dimensioned to be individually coupled to a selected one of the telephone line interconnect elements of the terminal block assembly to disconnect interconnection through the selected telephone line interconnect element between the incoming central office cable and an outgoing customer telephone line thereby isolating the incoming central office cable from the selected outgoing customer line while simultaneously causing the normally inactive receptacle element coupled to the plug member to be activated enabling testing of the incoming central office cable for default conditions by coupling a test device to the receptacle element;

    the receptacle element remaining inactive until the plug member is coupled to at least one of the telephone line interconnect elements of the terminal block assembly.
