Part 2 Call Routing 269
5.2 Incoming Traffic
5.2.1 Routing
Network interfaces with the same network-specific characteristics are all grouped
together in a trunk group. It is for example specified whether the network inter-
faces allocated to a trunk group are connected to a private leased-line network or
to the public network.
A call is routed via a trunk group to a direct dialling plan, a call distribution ele-
ment or a destination with a number from the internal numbering plan.
Each direct dial number is allocated a call distribution element. Several direct dial
numbers can be allocated to the same call distribution element.
A call distribution element is allocated destinations according to the circuit (see
"Call destination", page 227).
[1] One and the same trunk group cannot contain both analogue and digital network interfaces
