DSX-4U Circuit Modules

Each

 DSX-4U circuit module, shown in 

Figure 1-5

,

 provides access to the input and output of one

digital

 office equipment unit. The unit dimensions are approximately 15.02

Figure 1-5. DSX-4U Circuit Module

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 

Table 1-1
