Basic Configuration Using the Command-Line Interface
Configuring DS0 Trunk Group Dial Out

Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide
A trunk group can include any number of interfaces, but all the interfaces in a trunk group must use the
same type of signaling.
The TGRM subsystem has been enhanced to add fractional trunks to a trunk group. A fractional trunk is
a single DS0 line or a group of DS0 lines from a trunk.
Configure
The trunk-group command assigns a trunk to a trunk group by specifying the trunk group label
parameter and optionally setting the preference parameter.
The DS0 Dial Out Trunk Group feature adds two new optional keywords:
• timeslots list of timeslots
• preference preference
The timeslots keyword allows you to selectively add DS0 lines from a signaling circuit. Fractional trunk
groups are configured from the controller configuration mode only (because a PRI serial interface may
represent multiple member interfaces, including NFAS). If the timeslots option is not specified, all the
DS0s in the signaling circuit are assigned to the trunk group.
The preference keyword is configured after the timeslots option and is visible only when the timeslots
option is used. This helps to differentiate between the list of timeslots number and the preference number.
The following example shows the syntax for configuring selected DS0 lines using the timeslots keyword
and the preference keyword.

The following example shows the syntax for configuring all the DS0 lines in the signaling circuit:

Syntax Parameter Descriptions
The following examples show the configuration steps for PRI signaling. Controller T1 3 is a trunk
configured for PRI.
PRI Trunk Configuration
Step 1 Configure framing, clock source, DS0 group, and so forth.
AS5400(config)# controller T1 3
AS5400(config-controller)# framing esf
AS5400(config-controller)# clock source line secondary 3
AS5400(config-controller)# linecode b8zs
AS5400(config-controller)# pri-group timeslots 1-24
AS5400(config-controller)# !
label Trunk group label. Maximum length of the trunk group label is 127 alphanumeric
characters.
list of timeslots List of the interfaces from the signaling circuit to be added to the trunk group. The
range is 1 to 64.
preference Priority of the trunk group member in a trunk group. The range is from 1 (highest
priority) to 64 (lowest priority). The preference variable can be used to sort a list of
trunks in order. A trunk with no preference variable is given the highest preference.
