PBX Networking Technical Details
With closed numbering, the T-Comfort 930 DSL determines which route to seize from the telephone number
dialled. The information needed for routing a call can be configured in a numbering table containing up to
100 entries. You use this table to assign telephone numbers and/or ranges of telephone numbers to a par-
ticular route.
A default entry in the numbering table makes it possible to seize a “default route” for all remaining unas-
signed numbers. In particular, this simplifies configuration of the T-Comfort 930 DSL as a subsidiary system:
the only entry you assign to the default entry is the route to the host system
Example of closed numbering tables
The automatic switching of call requests (i.e. routing) by means of trunk group overflow or default numbering
can lead to “circular switching”.
To avoid this, a “transit” counter is incremented whenever a connection is switched through on Q.SIG lines.
When the configured maximum value is reached, further switching stops.
Technical Details
A different PBX number must be set for each T-Comfort 930 DSL in a PBX network. This setting can be found
in the Web console, in the menu PBX Configuration: System: Settings under the heading System linking .
You can also set the maximum value for the transit counter there. This value depends on the topology of the
PBX network and should allow the system to have the maximum number of further connections possible.
You can display the connection status of the lines at any time in the Configurator menu System info: PBX:
Trunks . You should check this in particular after making changes to a configuration to see whether all the
lines used for system networking are operable.
