16. Determine the optical loss of the optical facility from office records
or by making the required measurements.
17. Connect one pair of optical fibers from an adjacent shelf (site) to
new shelf MAIN 1 OLIU. Ensure that the correct fibers are
connected to the proper OLIU [MAIN 2(P) (MAIN-B-2(P)) in one
node to MAIN 1 in an adjacent node.]
18.
NOTE:
If the report in this step indicates wrong fiber connections or
no connection, verify that fecom is ON (rtrv-fecom:) and
check fiber integrity.
Use rtrv-map-neighbor: command to verify proper fiber
connections have been made to the adjacent node.
19. Connect optical fibers from the other adjacent shelf (site) to new
shelf MAIN 2(P) OLIU. Ensure that the correct fibers are
connected to the proper OLIU [MAIN 2(P) in one node to MAIN 1
(MAIN-B-1) in an adjacent node.]
20.
NOTE:
If the report in this step indicates wrong fiber connections or
no connection, verify that fecom is ON (rtrv-fecom:) and
check fiber integrity.
Use rtrv-map-neighbor: command to verify proper fiber
connections have been made to the adjacent node.
21. Verify that all alarm and status conditions clear. If nsa inc. VT
AIS alarm is present and no inc. OC-3 LOS or inc. OC-12
LOS alarm, check that all pass-through cross-connections have
been properly made using the rtrv-crs-vt1: command. If nsa
inc. STS AIS alarm is present and no inc. OC-3 LOS or
inc. OC-12 LOS alarm, check that all pass-through
cross-connections have been properly made using the
rtrv-crs-sts1: command.
