Alarm Maintenance

Note

The terms " Unidirectional Course Switched Ring" and " UPSR" may well appear in Cisco literature. These terms usually do not refer to applying Cisco ONS 15xxx items in a unidirectional path turned ring setup. Rather, these terms, and " Way Protected Nylon uppers Network" and " PPMN, " direct generally to Cisco's way protection characteristic, which may be employed in any topological network configuration. Cisco would not recommend having a path safety feature in different particular topological network settings. This section gives a information, severity, and troubleshooting procedure for each frequently encountered Gresca DWDM alert and condition. Tables 2-1 through 2-5 provide lists of DWDM alarms prepared by severity. Table 2-6 on page 2-7 provides a list of alarms arranged alphabetically. Table 2-7 gives definitions coming from all DWDM alarm logical items, which are the basis of the alert profile list in Stand 2-8 on page 2-13. For the comprehensive list of all conditions and guidance for using TL1 directions, refer to the Cisco SONET TL1 Command word Guide. A great alarm's troubleshooting procedure applies to both the Gresca Transport Controller (CTC) and TL1 type of that burglar alarm. If the fine-tuning procedure would 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 users, refer to the " Manage Alarms” part in the Gresca ONS 15454 DWDM Method Guide.
