4.1 Trunk groups
Fig. 2.29: 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,
essentially for incoming traffic. A number of settings are used for setting up spe-
cial network 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.
