Chapter2 Alarm Troubleshooting
2.7.48 DISCONNECTED
Step2 Make a minor provisioning change to the active database to see if applying a provisioning change clears
the alarm:
a. In node view, click the Provisioning > General > 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 could take up to a
minute.
Step3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call CiscoTAC (1-800-553-2447).
2.7.48 DISCONNECTED
Default Severity: Minor(MN), Non-Service-Affecting (NSA)
SONET Logical Object: SYSTEM
The Disconnected alarm is raised when CTC has been disconnected from the node. The alarm is cleared
when CTC is reconnected to the node.

Clear the DISCONNECTED Alarm

Step1 Restart the CTC application.
Step2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC (1-800-553-2447).
2.7.49 DS3-MISM
Default Severity: NotAlarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: DS3
The DS-3 Frame Format Mismatch condition indicates that a line type format mismatch on a signal
received on the DS-3 port of a 15310-CL-CTX, DS1-28/DS3-EC1-3, or DS1-84/DS3-EC1-3 card. The
condition occurs when the provisioned line type and incoming signal frame format type do no match.
For example, if the line type for a DS-3 port is set to CBit and the incoming signal line type is detected
as M13, then the port reports a DS3-MISM condition.

Clear the DS3-MISM Condition

Step1 In node view, double-click the CTX2500 card to display the card view.
Step2 Click the Provisioning > DS3 > Line tabs.
Step3 For the row on the appropriate port, verify that the Line Type column is set to match the expected
incoming signal (C bit or M13).
Step4 If the Line Type field does not match the expected incoming signal, select the correct LineType in the
drop-down list.
