2.7.381 SQUELCHED
In an example situation, an upstream MXP_2.5G_10G client port receive experiences a "loss of light,"
and this port raises CARLOSS, SIGLOSS, or LOS (determined by the payload type) locally. The port
also sends client signal fail to its downstream card. The downstream card raises a
page
The local client raises SQUELCHED if it also raises one of the following alarms for the client, all of
which are signalled by the upstream node:

On the MXP_MR_10G, the local client raises a SQUELCHED condition if the upstream client detects
one of the following alarms. Note that no corresponding local alarm is raised to indicate which of these
conditions is present upstream.

When troubleshooting the SQUELCHED condition locally, look for failures progressing upstream in the
following order. (If you are troubleshooting this alarm remotely, reverse the order of progress.)
• Local client alarms, as above
Local trunk alarms, as above
•
Remote (upstream) client receive alarms, as above
