PBX Networking Technical Details
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.
Some of the features possible in Q.SIG are not supported by Comfort Pro S with all their options, for example
callback on busy within the Q.SIG network. The call categories defined in Q.SIG (e.g. Emergency Call,
Operator, Normal) and the Q.SIG name transmission feature (“user names”) are fully supported.
The code digits to be used for seizing a route with open numbering are not transmitted to the destination PBX
and thus cannot be evaluated by it. To reseize a route (for example for a callback), you must set the appro-
priate digit prefixes in the trunk group configuration for the routes to be reseized.
t
If, for example, you are configuring a route which can be seized using routing code “5”
and have selected one or more bundles for this route, change the Prefix for dest. call
number at incoming internal setting to “5” for this bundle in order to enable the route
to be reseized.
Due to their hardware properties, not all S
0
ports of the Comfort Pro S can be fully used for TK system net-
working. Depending on the type of system, some ports can only be operated in the L1-Master mode or the L1-
Slave mode. The external S
0
ports can be set according to the following table.

well as the L1-Slave mode.
