2.4 MULTIPLEXER, FRONT-PANEL SWITCHES, INDICATORS, AND
JACKS
Figure 2-19 is a front view of the IMUX 2000 terminal multiplexer with its front door open. A
drop/insert multiplexer will look the same, except for the addition of a second CM4 Common Module.
The main power supply module and the E1 common module are expanded to show the location of all
front panel switches, indicators, and jacks. Functional descriptions of these switches, indicators, and
jacks appear in Tables 2-4 through 2-13. The numbers in the Item columns of these tables refer to the
numbers in the boxes shown in Figure 2-19.
