Configuration
The possible configurations described below can be set up in the Web console
using the
Telephony: Trunks
menu.
Bundles
A
bundle
is a group of lines of the same type and direction. A line can only be
assigned to one bundle.
Example of a PBX network with bundles
In the above example, the following bundles are configured for PBX 1:
●
Two S
0
lines in a multi-terminal configuration / SIP lines to the network
operator which are assigned to the “A” bundle.
●
Two S
0
point-to-point connections / Q.SIG-IP lines / SIP tie lines to PBX 2
which are assigned to the “C” bundle.
●
One S
0
point-to-point connection / Q.SIG-IP line / SIP tie line to PBX 3
which is assigned to the “E” bundle.
Note:
A line or a bundle cannot be seized directly. It is always
performed indirectly via a route.
Routes
A
route
is a group of bundles enabling a connection in one direction. If the first
bundle of a route is fully utilized, the next bundle is seized (“bundle
overflow”). One bundle can also be used for different routes.
In the above example, a route set up for PBX 1 allows a connection to PBX 2.
Bundle “C,” “E” and “A” are assigned to this route. If a user connected to PBX 1
wants to reach a party in PBX 2, lines will be seized in the following order:
PBX 1
PBX 2
PBX 3
