Abstract

The disclosed module is used in a digital telecommunication network having a digital cross-connect system. The module comprises a compact, self-contained, six jack port, dual monitor, digital signal cross-connect switching module. A plurality of modules comprise a system having provisions for cross-connect switching, rerouting, repair, patch and roll and monitoring. The interior of the module housing is specifically designed to conform with its internal assemblage so as to have the total effect of providing improved digital signal performance. The internal assemblage consists of a switching mechanism, monitoring circuits, resistors, conductors, inductors and insulators providing digital signal access through its six jack ports. Two of the jack ports are multi-purpose, having provisions for monitoring as well as digital signal access. A transmission system having this module has a digital signal range of at least 300 KHz to 100 MHz. The six jack port digital switching module paired with a like unit has an input jack port, an output jack port, a cross-connect input jack port, a cross-connect output jack port and four multi-purpose monitor jack ports. Each uses a make before break switch providing, without any loss of signal, the means for bridging, disengaging, isolating, connecting respective conductors, and terminating a first input signal through a 75 ohm resistor to ground when a plug is inserted into a second output jack port, and terminating a first output signal through a 75 ohm resistor to ground when a plug is inserted into a second input jack port.
