Remove Fiber Links Administration (Duplex
Systems)
The fiber links routing to and from the EPN cabinet being removed must be
unadministered before removing any hardware from the cabinet.
!
CAUTION:
Failure to remove fiber links administration before removing hardware
causes unnecessary alarm reports to INADS and causes errors that are very
difficult to clear.
The fiber links are administered to match hardware and the Fiber Optic Cable
Running List. Fiber link administration creates translation data by identifying the
endpoint pairs for each link. To properly remove the fiber links administration:
1. Type list fiber and press
Enter
. All administered fiber connections are
displayed. Make note of the fiber links to be removed.
2. Type change fiber link and press
Enter
. The Fiber Link Administration
screen appears. On screen 1:
a. Remove the
Board Location:
information for ENDPOINT-1 and
ENDPOINT-2. This is the cabinet, carrier, and slot that identifies the
physical location of an SNI or EI circuit pack that is the first endpoint
of the fiber link. Repeat for the remaining endpoints.

c. In the
DS1CONV Board Location
: field, remove the cabinet,
carrier, and slot that identifies the physical location of DS1 Converter
circuit pack in the first endpoint of the duplicate fiber link.

the duplicate fiber link called the B-PNC link.
d. The
DS1CONV Board Type
: field is a display only field.
e. The
Is one endpoint remoted via a DS1 Converter
