The DSX-4U module is designed for use with either E1, E3, E4 or STM-1 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 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
