Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Step 4 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 SES
This alarm occurs when the LIF is automatically set to the out-of-service state because of severely
errored seconds. The TDM line has a large amount of noise, causing an error rate greater than 10–3.
Framing and signal are within tolerance. This alarm indicates a degraded but functioning line.
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 terminations and cabling for the LIF are working. If you can identify the source of the
problem, resolve as necessary. Otherwise, proceed to Step 3.
Step 3 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 YELLOW
This alarm occurs when the receiving end reports a loss of the sent signal. This alarm is reported for
T1/E1 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 Connect an external loopback cable to the affected port.
If no alarms are produced, proceed to Step 3.
If alarms are produced, the port is causing the error. Replace the hardware component that is associated
with the port. See the associated media gateway documentation for more information on replacing the
component.
Step 3 Check for an open, short, or wiring error in the cable between the network interface port and your service
provider network interface unit T1/E1 terminal equipment. An open send pair can cause this condition.
If you find a wiring problem, replace the cable. If that does not clear the alarm, proceed to Step 4.
If you do not find a wiring problem, then proceed to Step 4.
