Technical Details PBX Networking
Some of the features possible in Q.SIG are not supported by T-Comfort 930 DSL 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.
Owing to their hardware properties, not all S
0
ports of the T-Comfort 930 DSL can be used for PBX net-
working without restrictions. Depending on the type of system, some ports can only operate in the L1 master
mode or L1 slave mode. The external S
0
ports can be set according to the following table.

S = Slave
M/S = Master/Slave

Note: The S
0
ports on add-on cards can be operated in both L1 master and L1 slave
mode.
