Configuration PBX Networking
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.
N
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 first searches for a free channel in the “C” bundle.
■
If all the lines in bundle “C” are busy, the system tries to set up a connection via bundle “E”. PBX 3
switches the connection through, provided it is appropriately configured (refer to Numbering starting on
page 126).
■
If it was not possible to set up an indirect connection via PBX 3, the system tries again via bundle “A”. The
“prefix” necessary for this can be configured with the route.
■
The user does not get a busy signal until the attempt to set up an indirect connection via the network
operator has also failed.
N
Note: If an internal connection is switched via a network operator, the call is signalled
using the external number of the calling PBX.
For each route you can define a randomly selectable code digit for seizing the route. You can also configure
whether a user is authorised to seize a particular route, whether LCR is to be used for one of the bundle.
