Abstract
A digital telecommunication network having a digital cross-connect system is described for facilitating the installation, testing, monitoring, restoration and repair of digital telecommunication apparatus. The system includes a plurality of digital cross-connect modules. Each of the modules has an input jack, an output jack, a cross-connect input jack, a cross-connect output jack, monitor output jack, and monitor input jack mounted on a front panel. Each of the modules has an input switch for cross-connecting an input conductor with a cross-connect input conductor to interconnect the input portion of two items of digital telecommunication apparatus. Each of the modules has an output switch for cross-connecting an output conductor with a cross-connect output conductor to interconnect the output portion of the two items of digital telecommunication apparatus. Each of the switches has means for disengaging the respective conductors when a plug is inserted into a respective jack to isolate the conductor.
