Chapter 2 Alarm Troubleshooting
The Ring is Squelching STS traffic condition is raised on an OC-N facility. If the node failure scenario
includes the source or destination node, then switching the nodes will squelch all the STSs that originate
from or destinate to the failure node. The condition resolves when the node is no longer failing.
This condition has an NA severity by default. However, the condition indicates that traffic is squelched
due to node failure, that is, traffic outage. Traffic outage can be caused by different problems, such as
multiple LOS alarms, AIS-L, or node power outage. STS-SQUELCH-L is symptomatic and indicates
that the user must investigate which node in a ring is being isolated and what is causing the node
isolation.
STS-SQUELCH-L is an informational condition.

2.7.400 SW-MISMATCH
The Software Mismatch condition occurs during software upgrade when there is a mismatch between
software versions. The card connecting to the TCC2/TCC2P is running an older version than the
TCC2/TCC2P is.

2.7.401 SWMTXMOD-PROT
The Switching Matrix Module Failure on Protect Slot alarm is raised by the Slot 10 cross connect card
if this card is active (ACT). Any kind of cross-connect card can raise this alarm. (Two exceptions are
given in the following paragraph.) SWMTXMOD-PROT occurs when a logic component internal to the
Slot 10 cross connect is out of frame (OOF) with a traffic card in the system. In this case, the alarm is
raised against the traffic card slot.
The XC-VXC-10G card can raise this alarm (in Slot 10) whether it is ACT or standby (SBY). The XCVT
card can raise SWMTXMOD-PROT against itself if the cross-connect card is OOF with a second logic
component on the same cross connect card.
