2.7.135 FORCED-REQ-SPAN
The Force Switch Request Span condition can apply to optical trunk cards in two-fiber or four-fiber
BLSRs when the Force Span command is applied to a BLSR SPAN to force traffic from working to
protect or from protect to working. This condition appears on the network view Alarms, Conditions, and
History tabs. The port where the FORCE SPAN command was applied is marked with an "F" on the
network view detailed circuit map.
FORCED-REQ can be raised in 1+1 facility protection groups. If traffic is present on a working port and
you use the FORCE command to prevent it from switching to the protect port (indicated by "FORCED
TO WORKING"), FORCED-REQ-SPAN indicates this force switch. In this case, the force is affecting
not only the facility, but the span.
