Abstract
A disconnect module 10 includes printed circuit board subassemblies 12 mounted on a mounting member 70 for connecting shielded twisted pair cables 2A and 2B, and for disconnecting the cables for testing the integrity of the circuits. Each module 10 also includes a ground bus 74 on the mounting member 70 for connecting drain wires 6 in multiple cables 2A and 2B through traces on printed circuit board subassemblies 12 to a ground reference. Each printed circuit board subassembly 12 includes an input electrical connector 30 and an output electrical connector 40, each of which can connect corresponding wire pairs 4 in four single pair shielded or screened cables, such as T1 cables. The connectors 30, 40 are mounted on the front of a printed circuit board 14 for easy access, and each connector includes a pivoting stuffer 36, 46. Disconnectable shunting connectors 60, mounted between the input and output connectors, normally connect corresponding wires in the two cables 2A, 2B, but can be removed to provide test posts for each pair circuit. The mounting member 70 includes a mounting track 72 for supporting multiple printed circuit board assemblies 12 in a row, and the ground bus 74 on th…
