Configuring T1 Lines Under SDH Framing

Procedures and examples for configuring T1 channel-groups on the 1-Port CHOC-12 ISE line card are

presented in the following sections:

• Using Extended Configuration Commands for T1 Lines in AU-3 Configuration Mode, page 24

• Creating a Logical Channel Group on a T1 Line, page 24

• Removing a Logical Channel Group from a T1 Line, page 18

• Using the ping Command to Verify Network Connectivity, page 18

• Setting the Clock Source on a T1 Line, page 27

• Using the ping Command to Verify Network Connectivity, page 18

• Using T1 Interface Loopback Modes, page 18

• Enabling Remote Performance Reports, page 30

• Configuring a BER Test on a T1 Line under SDH Framing with AU-3 AUG Mapping, page 30

Using Extended Configuration Commands for T1 Lines in AU-3 Configuration Mode

In AU-3 configuration mode, you must add the tug-2 tug-2-number modal prefix to the commands used

to configure T1 line attributes, where tug-2-number is a number in the range from 1 to 7. For example,

the AU-3 configuration command to configure the T1 framing takes the form:

tug-2 tug-2-number t1 t1-line-number framing {esf | sf}

Similarly, when you want to negate or reset the effects of a command by using the no form of the

command, you must apply the no form of the extended command.

Creating a Logical Channel Group on a T1 Line

You can create a logical channel group on a T1 line using 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. Table 4 describes the syntax of this command.

Table 4 T1 Line Channel Group Syntax

Range Description

tug-2 tug-2-number 1 to 7 When framing is SDH, AUG mapping is AU-3, and

mode of operation is c-11, tug-2-number is a number

in the range from 1 to 7.

t1 t1-line-number 1 to 4 In c-11 mode, a number in the range from 1 to 4.

channel-group

channel-group-number

0 to 23 Defines a logical channel group, identifying the set of

timeslots allocated to this n x DS0 channel in the

channelized T1 line (where n ranges from 1 to 24

timeslots).
