Maintenance-Object Repair Procedures
DS1 Facility Busyout
Busying out a MO allows service to be disconnected gracefully. Busyout puts the
object out-of-service until the repair procedures are completed.
DS1 facilities are busied out via the busyout ds1-facility command. When an
attempt is made to busyout the packet facility (or primary facility), system will print
a warning message indicating that the override option must be used to busyout
the packet facility. Busying out the packet facility will result in moving the packet
traffic to another facility and disconnecting circuit connections on that new facility.
The system will not allow the last packet DS1 facility to be busied out. In this
case, the DS1 CONV circuit pack must be busied out instead.
When the busyout ds1-facility command is executed, software communicates
with both DS1 CONV circuit packs in the DS1 CONV complex. If the board at
which the facility is being busied out is not accessible, then the abort code 2100
will be returned, if the board at the other end of the DS1 CONV complex is not
accessible, then the abort code 105 will be returned.
DS1 Facility Administration
DS1 facility administration is a part of the fiber link administration. DS1 options
are set on the second page of the Fiber Link Administration screen. For
critical-reliability systems, the third page of the Fiber Link Administration screen
contains the DS1 facility options for the B side of the PNC.
DS1 facility administration is explained in the following sections. Descriptions
given here do not provide complete coverage of fiber link administration.
Replacing a DS1 Facility
Disconnecting a DS1 facility is service disrupting except on critical-reliability
systems since they have PNC duplication.
For a duplex- or high-reliability system (no PNC duplication):
This procedure is destructive.
1. Busyout the DS1 facility via the busyout ds1-facility command.
2. Replace the DS1 facility.
3. Release the DS1 facility via the release ds1-facility command.
