Abstract

A subscriber module (40) for a network interface device (10) having a jack (100) defining a plug-receiving cavity (102) thereinto, and having a plug (50) insertable into the jack. The plug includes a plurality of interconnecting contacts (56) disposed at a mating end (58) thereof, and the jack includes first and second contacts (106, 112) secured within the plug-receiving cavity in spaced-apart disconnected pairs. Insertion of plug (50) into jack (100) moves interconnecting contacts (56) between associated ones of first and second contacts (106, 112) to electrically interconnect them, completing otherwise unconnected circuits between the distribution cable and the subscriber premise wiring. Preferably plug (50) includes a sealing member (74) therearound to seal the mating interface when plug (50) is inserted into jack (100). Conductors (36) of the premise wiring are terminable by insulation displacement techniques to terminals (164) using a stuffer cap (152), with terminals (164) connected to second contacts (112) by traces of circuit board (170) mounted within module (40), while first contacts (106) are electrically connected by other traces of board (170) to conductors (38) connected to the distribution cable.

Claims

1. A test port of a subscriber module of a network interface device wherein conductors of distribution cable are connected to conductors of premise wiring of a subscriber of telephone service, comprising:

a jack including a plug-receiving cavity and an array of contact members exposed for engagement at a mating interface within said plug-receiving cavity;

a plug member insertable into and removable from said plug-receiving cavity and including an array of interconnecting contact members exposed to be engageable with said jack contact members, with said plug member removable from said jack to permit insertion of another plug member for testing;

said contact members of said jack are arranged in associated pairs of first and second contact members adjacent said mating interface and having respective contact sections exposed along said mating interface in said plug-receiving cavity, and said first and second contact members being electrically unconnected to each other when said plug member is unmated from said jack, one of said first and contact members of each said pair being connected to a circuit extending to a distribution cable and the other thereof being connected to a circuit extending to premise wiring of a subscriber of telephone service; and

said contact members of said plug member being unconnected to any circuit when said plug member is unmated from said jack, each said contact member including a contact section associated with a respective said pair of said contact members of said jack, defining interconnecting contacts adapted to interconnect said ones and others of said pairs of contact members of said jack when said plug member is fully inserted into said jack, thus interconnecting otherwise unconnected ones of said conductors of said distribution cable and associated conductors of said premise wiring.

2. The test port as set forth in claim 1 wherein each of said contact sections of said first and second contact members is outwardly deflectable and disposed at an angle into said plug-receiving cavity prior to engagement and deflection outwardly by a said contact section of a corresponding said interconnecting contact of said plug.

3. A test port of a subscriber module of a network interface device wherein conductors of distribution cable are connected to conductors of premise wiring of a subscriber of telephone service, comprising:

a jack including a plug-receiving cavity and an array of contact members exposed for engagement at a mating interface within said plug-receiving cavity;

a plug member insertable into and removable from said plug-receiving cavity, with said plug member removable from said jack to permit insertion of another plug member for testing;

said contact members of said jack are arranged in associated pairs of first and second contact members adjacent said mating interface and having respective sections exposed along said mating interface in said plug-receiving cavity,

said first and second contact members being electrically unconnected to each other when said plug member is unmated from said jack, one of said first and contact members of each said pair being connected to a circuit extending to a distribution cable and the other thereof being connected to a circuit extending to premise wiring of a subscriber of telephone service; and

portions of said plug member being engageable, upon insertion of said plug member into said jack, with said exposed sections of said jack contact members to result in a respective conductive path being established between said first and second contact members of each said associated pair and the completion of circuits therebetween, thus interconnecting otherwise unconnected ones of said conductors of said distribution cable and associated conductors of said premise wiring.
