Configuring trunk groups

Like nailed channels that have been assigned a group number, switched channels in a trunk group can be referred to from a Connection profile and Call-Route profile to direct outbound calls to use that specific bandwidth. Trunk groups also serve a variety of other purposes, such as separating lines supplied by different carriers so those lines can be used as backup for each other if one switch becomes unavailable. The decision to use trunk groups is a global one. Once you have enabled the use of trunk groups, every switched channel must be assigned a trunk group number or it will not be available for outbound calls.

Trunk groups limit the number of channels available to multichannel calls, because only channels within the same trunk group can be aggregated.

To enable trunk groups, open the System profile and set Use-Trunk-Groups to Yes, as in the following example:

admin>	read system
SYSTEM	read
admin>	list
name =	""
system-rmt-mgmt = yes

use-trunk-groups = no idle-logout = 0 parallel-dialing = 2 single-file-incoming = yes analog-encoding = a-law sessionid-base = 0

admin> set use-trunk-groups = yes admin> write

Then assign the channels of each T1 line to a trunk group, as in the following example:

admin> list line channel 1 channel-usage = switched-channeltrunk-group = 9

phone-number = ""

call-route-info = { any-shelf any-slot 0 } nailed-group = 0

admin> set trunk-group = 4 admin> list .. 2 channel-usage = switched-channeltrunk-group = 9

phone-number = ""

call-route-info = { any-shelf any-slot 0 } nailed-group = 0

admin> set trunk-group = 4 admin> list .. 3 channel-usage = switched-channeltrunk-group = 9
