Configuring Framing

No Cisco IOS configuration is necessary. Framing type is determined during circuit configuration.

Configuring POS SPE Scrambling

To configure POS SPE scrambling, perform the following steps, beginning in global configuration
mode:
Command
Step 1
Router(config)# interface pos
number
Step 2
Router(config-if)# no pos

Step 3
Router(config-if)# no shutdown

SONET/SDH Alarms

The ML-Series cards report SONET/SDH alarms under both Cisco IOS and CTC/TL1. A number of path
alarms are reported in the Cisco IOS console. Configuring Cisco IOS console alarm reporting has no
effect on CTC alarm reporting. The
reported to the Cisco IOS console.
CTC/TL1 has sophisticated SONET/SDH alarm reporting capabilities. As a card in the ONS node, the
ML-Series card reports alarms to CTC/TL-1 like any other ONS card. On the ONS 15454 SONET, the
ML-Series card reports Telcordia GR-253 SONET alarms in the Alarms panel of CTC. For more
information on alarms and alarm definitions, refer to the "Alarm Troubleshooting" chapter of the
Cisco ONS 15454 Troubleshooting Guide, or the Cisco ONS 15454 SDH Troubleshooting Guide.

Configuring SONET/SDH Alarms

All SONET/SDH alarms are logged on the Cisco IOS CLI by default. But to provision or disable the
reporting of specific SONET/SDH alarms on the Cisco IOS CLI, perform the following steps beginning
in global configuration mode:
