CAUTION:
DDM-2000 circuit packs contain static sensitive components
which can be damaged by electrostatic discharge. A static
ground wrist strap must be worn when handling the circuit
packs. See electrostatic discharge considerations in
Trouble Clearing: TAD-100.
Determine which DS3 group is to be discontinued and verify no
alarms exist on the system.
2.
NOTE:
The following operation may activate the office critical, major,
or minor alarm. The audible alarm may be suppressed by
depressing the ACO pushbutton (opr-aco command).
At the DSX-3/STSX cable cross-connect point at the terminating
(drop) nodes, remove the DS3 service (signal) from the DS3
group being discontinued. (FAULT LED flashes on DS3 circuit
packs with signal removed).

NOTE:
The UPD/INIT pushbutton on the SYSCTL is recessed to
prevent its accidental operation. You will need a small
pointed object such as a ball-point pen.
At the terminating drop nodes, momentarily depress the UPD/INIT
pushbutton on the SYSCTL circuit pack or use the upd command
to update the equipment list. (Flashing FAULT LEDs go off.)
