SYNCLOSS
Default Severity: Major (MJ), Service-Affecting (SA)
Logical Objects: FC, GE, ISC, TRUNK, EQPT
The Loss of Synchronization on Data Interface alarm is raised on MXP card client and trunk ports when there
is a loss of signal synchronization on the port. The SYNCLOSS alarm is raised on OTU2_XP card 10GE and
10G FC client data ports when there is a loss of signal synchronization on the port. This alarm is demoted by
the SIGLOSS alarm.
Clear the SYNCLOSS Alarm
SUMMARY STEPS
1. Ensure that the data port connection at the near end of the SONET or SDH (ETSI) link is operational.
2. Verify fiber continuity to the port. To do this, follow site practices.
3. View the physical port LED to determine whether the alarm has cleared.
DETAILED STEPS
Step 1 Ensure that the data port connection at the near end of the SONET or SDH (ETSI) link is operational.
Step 2 Verify fiber continuity to the port. To do this, follow site practices.
Step 3 View the physical port LED to determine whether the alarm has cleared.
• If the LED is green, the alarm has cleared.
• If the port LED is clear (that is, not lit green), the link is not connected and the alarm has not cleared.
• If the LED is red, this indicates that the fiber is pulled.
If the alarm does not get cleared, you need to report a Service-Affecting (SA) problem. Log into the Technical Support
