4.1 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 × 1.78 × 23.04 cm
(6.00
× 0.70 × 9.02 inches).
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 .
