Test Jacks

For 2-port and 4-port DSU/CSUs, six test jacks are located on the front panel (Figure 4-1). The Mon (Monitor) branch of the menu tree allows you to select either EQPT (Equipment) or NET (Network).

NOTE

The single-port DSU/CSU provides only Network Monitor In and Network Monitor Out test jacks. There is no Mon (Monitor) selection in the menu tree.

The 2-port and 4-port DSU/CSU test jack functions are shown in Figure 4-2and described in Table 4-7.
