14.4.118 SYNCSEC
•
Minor, Non-Service-Affecting
A loss of timing on secondary reference (SYNCSEC) alarm occurs when the ONS 15327 loses the
secondary timing source (reference 2). The ONS 15327 uses three ranked timing references. The timing
references are typically two BITS-level or line-level sources and an internal reference. If SYNCSEC
occurs, the ONS 15327 should switch to the third timing source (reference 3) to obtain valid timing for
the ONS 15327. This switch also triggers the
alarm.
Procedure: Clear the SYNCSEC Alarm on the XTC Card
Step 1
From the node view, click the
Provisioning
>
Timing
tabs.
Step 2
Check the current configuration of the REF-2 for the NE Reference.

Step 4
If the secondary timing source is an incoming port on the ONS 15327, follow the procedure in the
14.4.119 SYNCTHIRD
•
Minor, Non-Service-Affecting
A loss of timing on third reference (SYNCTHIRD) alarm occurs when the ONS 15327 loses the third
timing source (reference 3). The ONS 15327 uses three ranking timing references. The timing references
are typically two BITS-level or line-level sources and an internal reference. If SYNCTHIRD occurs and
the ONS 15327 uses an internal reference for source three, then the XTC card may have failed. The ONS
15327 often reports either
or
alarms after a SYNCTHIRD alarm.
Caution
Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband
cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
