Alarm Procedures
2.6.43 DBOSYNC
• Major (MJ), Non-Service Affecting (NSA)
The Standby Database Out of Synchronization (DBOSYNC) alarm occurs when the standby XTC “To
be Active” database does not synchronize with the “Active” database on the active XTC.
Caution If you reset the active XTC while this alarm is raised, you will lose current provisioning.
Procedure: Clear the DBOSYNC Alarm
Step 1 Save a backup copy of the active XTC database. Complete the “Back Up the Database” procedure in the
Cisco ONS 15327 Procedure Guide.
Step 2 Make a minor provisioning change to the active database to see if applying a provisioning change if
applying a provisioning change clears the alarm:
a. In node view, click the Provisioning > General tabs.
b. In the Description field, make a small change such as adding a period to the existing entry.
The change causes a database write but does not affect the node state. The write might take up to a
minute.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC
(1-800-553-2447).
2.6.44 DS3-MISM
• Not Alarmed (NA), Non-Service Affecting (NSA)
The DS-3 Frame Format Mismatch (DS3-MISM) condition indicates a DS-1 frame format mismatch on
a signal transiting the XTC-28-3 card. The condition occurs when the provisioned line type and
incoming signal frame format type do no match. For example, if the line type is set to D4 for a DS-1
transiting the XTC-28-3 card, and the incoming signal’s line type format is detected as unframed, then
the ONS 15327 reports a DS3-MISM condition.
Warning
Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100
mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than
those specified might result in hazardous radiation exposure.
Note You can only provision DS-1 line frame format on the XTC-28-3 card. DS-3 line format is not
provisionable.
