Step 4 If your port is configured to use D4 framing, the port might intermittently detect yellow alarms because

the packet data might contain the pattern that is used to signal yellow alarm in D4 framing. If possible,

switch to ESF framing in both the terminal equipment and the line equipment.

If switching the framing does not clear the alarm, proceed to Step 5.

Step 5 Contact the Cisco TAC to analyze the problem further and to determine a solution. For more information

about contacting the Cisco TAC, see the “Obtaining Documentation and Submitting a Service Request”

section on page xviii.

LIF: IDLE CHANGE

This alarm occurs when the physical line fails because its cable is broken or not plugged in. This alarm

is reported for V.35 facilities only.

Corrective Action

To correct the problem, perform the following steps:

Step 1 To collect system data, see the method that is described in the “Collecting System Data for Cisco TAC”

section on page 6-93.

Step 2 Verify that the V.35 cables between the port and the far-end are working correctly.

If you find a problem with a V.35 cable, replace the cable. If that does not correct the problem, proceed

to Step 3.

If you do not find a problem with the V.35 cables, proceed to Step 3.
