6.2.2.2 Creating the Exchange Trunk Group
An exchange trunk group is created in system 1 for the lines leading to the public
network:
1. Create a trunk group in system 1 with the line to the public network
(trunk group 1-1).
You need to set the exchange trunk group for the public network:
2. Select the following settings in the trunk group configuration of trunk
group 1-1:
– Name = public network
– Network type = public
– Protocol = DSS1
6.2.3 Route Configuration
Once you have created the trunk groups, configure the routes.
Allocating the Trunk Groups
Three routes are provided for in each system (one for each system in the network
and one for the public network. You do not need one for your own system). The
trunk groups are now allocated to the routes:
1. In system 1 allocate the trunk groups to the routes:
– Route 1-1: trunk group 1-1 (trunk group to the public network)
– Route 1-6: Trunk group 1-4 (trunk group to system 2)
– Route 1-7: Trunk group 1-5 (trunk group to system 3)
2. In system 2 allocate trunk group 2-4 to all the routes (all the routes use the
same trunk group as all the calls go via system 1):
– Route 2-1: Trunk group 2-4 (trunk group to system 1)
– Route 2-5: Trunk group 2-4 (trunk group to system 1)
– Route 2-7: Trunk group 2-4 (trunk group to system 1)
3. In system 3 allocate trunk group 3-4 to all the routes. (All the routes use the
same trunk group as all the calls go via system 1):
– Route 3-1: Trunk group 3-4 (trunk group to system 1)
– Route 3-5: Trunk group 3-4 (trunk group to system 1)
– Route 3-6: Trunk group 3-4 (trunk group to system 1)
