Trunk groups

Trunk groups in relation to the other routing elements
Network interfaces with the same characteristics are grouped together in a trunk
group. For example, it is specified whether the network interfaces allocated to a
trunk group are connected to a private network or the public network.
The trunk group is the key element for call traffic with the network. The trunk group
configuration is allocated important routing and identification functions, essen-
tially for incoming traffic. A number of settings are used for setting up special net-
work configurations, for instance the optimum integration of PINXs by third-party
manufacturers. The initialization values of these settings are such that they do not
need to be adapted any further for conventional configurations.
