CAUTION:
Incorrect ADU option switch settings can cause service interruptions. Do
not change any option switches except the ones listed for equipping
digroups. For FPB Mode 1 systems, removing the ADU will interrupt
service on digroup A. Therefore, this procedure requires that a Mode 1
system has all digroups equipped.
NOTE:
If the ADU you are installing is a replacement, the system configuration
(positions 1,2,7, and 8) options must be set as directed in the previous
Steps.
Remove ADU (Figure 1) from bank being equipped.

• 5 - Toward the number (closed) to option digroup AB equipped.
• 6 - Toward the number (closed) to option digroup CD equipped (if
required).
