A telecommunications chassis, module, and repeater circuit for use with signals having data rates including STM-1 (155.52 megabits per second) are disclosed. The chassis provides structures for establishing shielding and heat dissipation for the circuitry modules it contains including an outer and an inner Faraday box with an integrated ventilation pattern for circulating air. The module provides its own structures for establishing shielding and heat dissipation including a Faraday box and a ventilation pattern. The repeater circuit provides the ability to bridge a data signal between a monitor jack of one device and a higher signal level input jack of another device through multiple amplification stages and circuit board structures. The telecommunications chassis, module, and repeater circuit can be used in conjunction.

Telecommunications chassis, module, and bridging repeater circuitry

A monitor circuit for indicating whether a digital cross-connect bay has a cross-connect jack that cross connects equipment being tested that includes a non-intrusive sensor for sensing current changes in a power feed line of the bay being monitored. The non-intrusive sensor is operatively coupled to a sensor device that generates a signal to activate an external sensor if a current change is detected by the sensor. The sensor device is powered from the same power supply as the bay it is monitoring.
