DLP-A218 Provision Path Protection Selectors
If you do not see any BLSR exercise conditions, click the Filter button and verify that filtering is not
turned on. Also, check that alarms and conditions are not suppressed for a node or BLSR drop cards. See
the
information.

Note
Circuit Attributes page of the Circuit Creation wizard sets the values only for path protection-protected
spans. The circuit source and destination use the node default values of 10E-4 for SD-P and 10E-6 for
SF-P for unprotected circuits and for the source and drop of path protection circuits.
In the UPSR area of the Circuit Attributes page, set the path protection path selectors:

Verify that the alarm filter is not on. See the
page 19-17 as necessary.
Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve
them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide if necessary.
This task provisions path protection selectors during circuit creation or
during a topology upgrade conversion.

Provisioning or higher
Provision working go and return on primary path—Check this box to route the working path on one
fiber pair and the protect path on a separate fiber pair. This feature only applies to bidirectional path
protection circuits.
Revertive—Check this box if you want traffic to revert to the working path when the conditions that
diverted it to the protect path are repaired. If you do not choose Revertive, traffic remains on the
protect path after the switch.
Reversion time—If Revertive is checked, click the Reversion time field and choose a reversion time
from the drop-down list. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes. This is the
amount of time that will elapse before the traffic reverts to the working path. Traffic can revert when
conditions causing the switch are cleared.
SF threshold—Set the path protection path-level signal failure bit error rate (BER) thresholds.
SD threshold—Set the path protection path-level signal degrade BER thresholds.
