Chapter 7 4-Port Channelized OC-3/STM-1 Line Card Configuration
The default is SONET.
Use the no form of the command to remove framing and return the line card to the default values.
The following example shows you how to specify SONET framing for the 4-port STM-1 line card in slot
2:
Router(config)# controller sonet 2/0/0
Router(config-controller)# framing sonet
Configuring the SONET Controller Loopback Mode
You can enable SONET controller loopbacks by using the loopback command.
loopback
[no] loopback
The default is no loopback.
Use the no form of the command to stop a loopback.
For more information on the loopback command, refer to the online Cisco 10000 Series ESR
Troubleshooting Guide.
The commands in this example run an internal loopback on the 4-Port Channelized OC-3/STM-1 line
card in slot 2:
Router(config)# controller sonet 2/0/0
Router(config-controller)# loopback internal

Designating an STS-1 Path as a T3 or VT under SONET Framing
When the 4-port STM-1 line card is configured for SONET framing, you can use the path command to
designate an STS-1 path as a T3 or VT controller. You can designate up to 12 STS-1 channels.
