Logical Objects: CLIENT
The Loss of Synchronization on Data Interface alarm is raised on the NCS 1002 client and trunk ports when
there is a loss of signal synchronization on the port. This alarm is demoted by the SIGLOSS alarm.
Clear the SYNCLOSS Alarm
Step 1
Ensure that the data port connection at the near end of the Ethernet link is operational.
Step 2
Verify the fiber continuity to the port. To do this, follow site practices.
Step 3
For 100 GE, verify that the FEC settings match between the router and NCS 1002.
If the alarm does not get cleared, you need to report a Service-Affecting (SA) problem. Log into the Technical Support

SQUELCHED Alarm
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Objects: GE, CLIENT
The client signal squelched condition is raised by the NCS 1002 in the following situations:
• Laser-squelch is configured under the client controller.
Laser-squelch is supported only on QSFP+, QSFP28 LR4, and QSFP28 CWDM4
pluggables.
Note
• Laser-squelching occurs on a QSFP pluggable when all the four lanes operating in the 10 GE client mode
are turned off after the upstream receive facility has experienced a loss of signal (such as optical LOS,
LOF).
• A MXP or TXP client facility detects that an upstream receive facility has experienced a loss of signal
(such as optical LOS, LOF). In response, the client facility transmit is turned off (SQUELCHED). The
upstream receive facility is the trunk receive on the same slice as the client.
• The client will squelch if the upstream trunk receive (on the trunk port carrying the client payload)
experiences a LOS, or LOF (TRUNK) alarm.
• The client will squelch if any one of trunk ports receive LOS, or LOF. In this case, the client port is
mapped to two trunk ports. For example, the HundredGigECtrlr 0/0/0/9 is mapped to the
CoherentDSP0/0/0/12 and the CoherentDSP0/0/0/13 for a 10 GE to 100 GE hw-module config.
The local client raises a SQUELCHED condition if the local trunk raises one of the following alarms:
