Abstract
Abstract In a digital signal cross-connection system, the functions of the cross-connection of equipments and the access to those equipments for testing purposes are separated. The jacksets utilized for testing access are removed from the cross-connection bays and are considerably fewer in number than the terminations on the cross-connection bays. A concentrator switch is interposed between the jacksets and the cross-connection bays so that access is provided to the transmit and receive leads to the cross-connection bays only on an as needed basis, the concentrator switch also providing a control function for disconnecting the digital equipments from the cross-connection bays.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
A digital signal cross-connection bay comprising jumpers for manually interconnecting terminals connectable to distinct digital equipments, a plurality of test access ports, said test access ports including test jack positions; and means for connecting said test positions to said bay terminals, characterized in that said connecting means comprises a concentrator switch interposed between said digital cross-connection bay terminals and said test access ports, the number of said test access ports being less than the number of said digital cross-connection bay terminals, and electronic means for automatically operating said concentrator switch to connect a distinct one of said test access ports to the digital equipment normally connectable to a distinct one of said cross-connection bay terminals.
