The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration. This chapter gives a description, severity, and troubleshooting procedure for each commonly encountered Cisco DWDM alarm and condition. Tables 2-1 through 2-5 provide lists of DWDM alarms organized by severity. Table 2-6 on page 2-7 provides a list of alarms organized alphabetically. Table 2-7 gives definitions of all DWDM alarm logical objects, which are the basis of the alarm profile list in Table 2-8 on page 2-13. For a comprehensive list of all conditions and instructions for using TL1 commands, refer to the Cisco SONET TL1 Command Guide . An alarm’s troubleshooting procedure applies to both the Cisco Transport Controller (CTC) and 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 (1-800-553-2447). For more information about alarm profiles, refer to the “Manage Alarms” chapter in the Cisco ONS 15454 DWDM Procedure Guide.
Unless otherwise noted, ONS 15454 refers to the ANSI and ETSI versions of the platform.
2.1 Alarm Indexes
The following tables group alarms and conditions by their default severities in the ONS DWDM system. These severities are the same whether they are reported in the CTC Alarms window severity (SEV) column or in TL1.
The CTC default alarm profile contains some alarms or conditions that are not currently implemented but are reserved for future use.

Chapter 2 Alarm Troubleshooting 2.1.1 Critical Alarms (CR)
The CTC default alarm profile in some cases contains two severities for one alarm (for example, MJ/MN). The 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.
