Chapter 2 Alarm Troubleshooting

2.7.242 TX-AIS

Note For more information about Ethernet cards, refer to the Cisco ONS 15310-CL and Cisco ONS 15310-MA Ethernet Card Software Feature and Configuration Guide.

Clear the TPTFAIL (CE100T) Alarm

Step 1 Clear any alarms being reported by the OC-N port on the CE100T-8 circuit.

Step 2 If no alarms are reported by the OC-N port, or if the “PDI-P” condition on page 2-113is reported, the problem could be on the far-end G-Series Ethernet port. Clear any alarms, such as CARLOSS, reported against the far-end port or card.

Step 3 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) in order to report a Service-Affecting (SA) problem.

2.7.242 TX-AIS

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

SONET Logical Objects: DS1, DS3

The Transmit (TX) Direction AIS condition is raised by the ONS 15310-CL or ONS 15310-MA backplane when it receives a far-end DS-1 LOS.

Clear the TX-AIS Condition

Step 1 Determine whether there are alarms on the downstream nodes and equipment, especially the “LOS (OCN)” alarm on page 2-98, or OOS ports.

Step 2 Clear the downstream alarms using the applicable procedures in this chapter.

Step 3 If the condition 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).

2.7.243 TX-LOF

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Objects: DS1, DS3

The Transmit Direction LOF condition is transmitted by the backplane when it receives a DS-1 TX-LOF.

This alarm is raised only at the transmit (egress) side.

Clear the TX-LOF Condition

Step 1 Complete the “Clear the LOF (DS1) Alarm” procedure on page 2-86.
