NOTE:
The following operation may activate the office major, minor,
or no alarm. The audible alarm may be suppressed by
depressing the ACO button.
NOTE:
One of the terminating nodes for the DS1 service may be
equipped with STS1E circuit packs to provide an EC-1
interface for the DS1 service.
At the DSX-1 at the DS1 terminating nodes, remove the DS1
signals associated with the port(s) being discontinued. (FAULT
LEDs begin flashing on DS1/DS1PM circuit pack with signals
removed.)
3.
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 to operate it.
Momentarily depress the UPD/INIT buttonontheSYSCTL at the
DS1 terminating nodes or use the upd command to update the
equipment list. (Flashing FAULT LEDs go off.)
4. If a craft interface terminal (CIT) is available, use the
rtrv-state-eqpt: command to verify that the right port has
been changed from in-service (i)toauto (a)state.

CAUTION:
Removing the wrong cross-connection may cause service
interruption. Use the
rtrv-crs-( )
command to determine
the proper cross-connections.
From work order or rtrv-crs-( ) command, determine the
cross-connections for circuit being discontinued.
