Note: Q.SIG-IP cannot be operated using a connection with
NAT. For a Q.SIG-IP connection, a branch connection or an-
other VPN connection is required.
12.3 Configuration
The possible configurations described below can be set up in the Web console
using the
Telephony: Trunks menu.
12.3.1 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 al-
ways performed indirectly via a route.
12.3.2 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.
