1.7.68 EXTRA-TRAF-PREEMPT

The EXTRA-TRAF-PREEMPT alarm is not used in the ONS 15310 platforms in this release. It is
reserved for future development.

1.7.69 FAILTOSW

The Failure to Switch to Protection Facility condition occurs when a working or protect optical facility
switches to its companion port by using a MANUAL command. For example, if you attempt to manually
switch traffic from an unused protect port to an in-service working port, the switch will fail (because
traffic is already present on the working port) and you will see the FAILTOSW condition.

Clear the FAILTOSW Condition

Look up and troubleshoot the higher-priority alarm. Clearing the higher-priority condition frees the port
Step 1
and clears the FAILTOSW.
