Channelized T1 Commands under SONET or SDH Framing
You can enter commands to modify aspects of a T1 interface from controller configuration mode for a
T3 interface. This section describes the commands for:
•
•
•
•
•
•
After you configure a T1 interface, you can add encapsulation, routing, and other instructions by entering
interface configuration mode. For example:
Router(config)# interface serial 1/0/0.1/4:18
Setting the Framing Format
You can specify the T1 interface framing format using the following command:
t1 t1-number framing
[no] t1 t1-number framing
Where:
•
•
•
The default framing format is extended super frame (ESF).
Use the no form of the command to return framing to its default value.
Examples:
•
•
OL-8834-04
Router(config-controller)# tug-2 1 t1 5 channel-group 20 timeslots 10
Router(config-controller)# tug-2 1 t1 5 channel-group 21 timeslots 7-9, 24
In the following example, channel group 20 is removed:
Router(config-controller)# controller au3 2/0/0.2
Router(config-controller)# no tug-2 1 t1 5 channel-group 20

t1-number is T1 interface 1 to 28
framing is either extended super frame (ESF) or super frame (SF). You can set SF hdlc-idle to 0x7E
or 0xFF
hdlc-idle options allow you to set the idle pattern for the T1 interface to either 0x7e (the default) or
0xFF
Set SF framing format for T1 interface 6.
Router(config)# controller T3 1/0/0.1
Router(config-controller)# t1 6 framing sf
Set ESF framing format for T1 interface 16:
Router(config)# controller T3 1/0/0.1
Router(config-controller)# t1 16 framing esf
