Step Action
3 Check for the pass through cross-connects with the neighboring network
elements B and D.
Note: Traffic on all the unprotected circuits passing through either D-1-4-3 or
B-1-2-3 will be lost while deleting the network element C.
4 Force all protected cross-connections on D-1-4-3 towards D-1-2-3 (using
force to working or force to protect) and B-1-2-3 towards B-1-4-3 (using force
to protect or force to working depending on whether 1-2-3 is working or
protect, respectively).
5 At network element C, disconnect all the fibers going to network elements B
and D. Perform the necessary pass through at network element C. Measure
the Rx power at network element B and D and verify that they are within
specifications.
Refer to the Planning Guide, S78-1002-110 for the specifications.
6 If applicable, clear the forced switches, operated at step 4, on network
elements B and D.
