An alarm troubleshooting procedure applies to both the Cisco Transport Controller (CTC) and
Transaction Language One (TL1) version of that alarm. If the troubleshooting procedure does not clear
the alarm, log into the Technical Support Website at http://www.cisco.com/techsupport for more
information or call the Cisco Technical Assistance Center (TAC) (1 800 553-2447).
2.1 Alarm Indexes by Default Severity
The following tables group alarms and conditions by their default severities in the ONS 15600 SDH
system. These severities are the same whether they are reported in the CTC Alarms window severity
(SEV) column or in TL1.
Note
The CTC default alarm profile contains some alarms or conditions which are not currently implemented
but are reserved for future use.
Note
The CTC default alarm profile in some cases contains two severities for one alarm (for example,
MJ/MN). The ONS 15600 SDH platform default severity comes first (in this example, MJ), but the alarm
can be demoted to the second severity in the presence of a higher-ranking alarm. This is in accordance
with Telcordia GR-474-CORE.
