Abstract
A digital communication network having a digital cross-connect system is described for facilitating the insulation, testing, monitoring, restoration and repair of digital telecommunication apparatus. The system includes a plurality of digital cross-connect modules 10. Each module 10 has an input jack 32, and output jack 34, cross-connect input jack 36 and cross-connect output jack 38 mounted on the front panel for providing front panel access. Each of the jacks is mounted to a printed circuit board having printed circuit board terminals. BNC or TNC coaxial connectors are mounted on the rear panel. The jacks and the connectors are interconnected via printed circuit board traces. Each of the modules has a switch structure for interconnecting jacks and for providing termination before break capability. Each of the jacks automatically interrupts the circuit when a coaxial plug is inserted into a respective jack to isolate the conductor.
