## Abstract

A jack module including a switching jack subassembly and monitor jack assembly includes a printed circuit board between the subassemblies. The subassemblies and circuit board are commonly housed. The printed circuit board contains monitor circuitry.

## Claims

### Claim 1

A jack module comprising:
(a) a first jack subassembly including:
i. a first and a second coax center conductor each extending from a first end to a second end;
ii. first support means for supporting said first and second coax center conductors in spaced apart alignment and including a first electrically grounded support casing at least partially surrounding each of said first and second coax conductors with insulation supports maintaining said first and second coax conductors within said first support casing; said first support casing including first and second ports associated with first ends of said first and second conductors, respectively, and first and second connectors associated with second ends of said first and second, respectively, conductors;
iii. a jack switch having first spring means biased against each of said first and second coax center conductors to electrically connect said first and second center conductors and means for breaking electrical connection between said first and second center conductors upon insertion of a plug into either of said first and second ports;
(b) a second jack subassembly including:
i. a third coax center conductor extending from a first end to a second end;
ii. second support means including a second electrically grounded support casing at least partially surrounding said third coax center conductor and insulation support for supporting said third coax center conductor within said second support casing;
(c) a common housing surrounding said first and second jack subassemblies and having means for interlocking with said first and second support casings to retain said first and second jack subassemblies in spaced-apart alignment with said jack assemblies spaced-apart by a predetermined dimension and with said housing hollow within said dimension to define a cavity therein.

### Claim 2 (depends on 1)

A jack module according to claim 1 comprising a circuit means disposed within said cavity.

### Claim 3 (depends on 2)

A jack module according to claim 2 wherein said circuit means includes means for monitoring a signal along either one of said first and second coax center conductor by accessing a signal on either one of said first and second coax center conductors.

### Claim 4 (depends on 3)

A jack module according to claim 3 wherein said circuit means is an inductive monitoring circuit.

### Claim 5 (depends on 2)

A jack module according to claim 2 wherein said circuit means includes a printed circuit board disposed within said cavity and secured to said housing.

### Claim 6 (depends on 1)

A jack module according to claim 1 wherein said housing includes a rear wall spaced from said first support casing with opposing surfaces of said rear wall and first support casing defining an access opening in communication with an interior of said housing.

### Claim 7 (depends on 1)

A jack module according to claim 1 wherein said first jack subassembly includes a front portion and a rear portion each having:
(a) a front support casing and a rear support casing cooperating to define said first support casing;
(b) a first and a second front coax conductor and a first and a second rear coax conductor cooperating to define said first and second, respectively, coax center conductors;
said first and second front coax conductors supported within said front support casing;
said first and second rear coax conductors supported within said rear support casing;
said first and second ports secured to said front support casing;
said first and second connectors secured to said rear support casing; and
each of said front and rear support casings including means for interlocking with interior surfaces of said housing to retain said front and rear support casings in desired alignment within said housing.
