How to Configure Layer 1 Features

Cisco IOS Release 12.0(27)S1

To configure a T1 line, you must enter SONET controller configuration mode and specify the line card

slot and port, and then enter AU-3 configuration mode.

The following example shows the process of configuring a logical channel group in c-11 mode. The first

T1 line in the fourth TUG-2 group is assigned to logical channel group 15 with channelized timeslots 1

to 5, and 20 to 23:

Router(config)# controller sonet 6/0

Router(config-controller)# au-3 1

Router(config-ctrlr-au3)# tug-2 4 t1 1 channel-group 15 timeslots 1-5, 20-23

Router(config-ctrlr-au3)#

Note After a T1 channel group is configured, it appears to the Cisco IOS software as a serial

interface; therefore, all the configuration commands for a serial interface are available, but

not all commands are applicable to the T1 channel group.

All the encapsulation formats, such as PPP, HDLC, and Frame Relay are applicable to the

configured T1 channel group. Be sure that you are in serial interface configuration mode

when you set the encapsulation format.

All the switching types that are applicable to a serial interface are also applicable to the

configured T1 channel group.

Removing a Logical Channel Group from a T1 Line

You can remove a logical channel group from a T1 line (or a T1 line) with the no form of the

tug-2 tug-2-number t1 t1-line-number channel-group channel-group-number

timeslots list-of-timeslots [speed {56 | 64}] AU-3 configuration command.

The following example shows the process of removing a logical channel group in c-11 mode, and uses

port 0 of the 1-Port CHOC-12 ISE line card in slot 6 of a Cisco 12000 Series Router. The first T1 line

in the fourth TUG-2 group is being removed from logical channel group 15 with channelized timeslots

1 to 5, and 20 to 23:

Router(config)# controller sonet 6/0

Router(config-controller)# au-3 1

Router(config-ctrlr-au3)# no tug-2 4 t1 1 channel-group 15 timeslots 1-5, 20-23

Router(config-ctrlr-au3)#

timeslots

list-of-timeslots

1 to 24 Combination of subranges within 1 to 24 (each

subrange is a list of timeslots that makes up the T1

line).

speed {56 | 64} 56 or 64 kbps Optional keyword and argument that sets the DS0

speed. The default speed is 64 kbps.
