The 3160 DSU/CSU front panel (Figure 3-1) consists
of an LCD that displays messages, a keypad, 12 LEDs,
and six test jacks. The Model 3161 CSU faceplate
contains these same 12 LEDs and six test jacks (see

the SDCP of the 3000 Series Carrier (see Figure 3-3). A
description of the front panel is contained in Chapter 1,
