PBX Networking
166
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 to the network operator which are
assigned to the “A” bundle.
•
Two S
0
point-to-point connections to PBX 2 which are assigned to the “C” bundle.
•
One S
0
point-to-point connection 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:
A
B
C
E
D
