The DSX-4H module is designed for use with either DS3, STS-1, STS-3, or DS4NA
interfaces; however, only one type of interface should be terminated at any one cross-connect
system bay. The module has standard or midsize coaxial jacks for testing and patching. BNC
or TNC coaxial connectors at the back of the module are used for connecting the equipment
in/out cables and cross-connect jumpers. Specific functions of the circuit module components
are defined in

LOCATION FUNCTION
Front Used to identify the opposite end of a
cross-connect. The tracer lamp flashes for
approximately 30 seconds whenever the
tracer lamp switch is pulled out, and
remains lit while the tracer lamp switch
is left pulled out. If the module is cross-
connected to another module, the tracer
lamp on that module will also flash
approximately 30 seconds and then
remain lit.
Front Provides bridged access to the output
signal of connected office equipment to
allow monitoring without interruption.
