Ascotel IntelliGate 2025/2045/2065
430 Features Part 2
Example: Callback if busy
"Callback if busy" is supported within the private network. Compatibility for this
feature between private network (QSIG protocol) and public network (DSS1 pro-
tocol) is guaranteed. It is possible to activate callback between A and C and
between B and C (Fig. 2.159) if the public network supports the feature end-to-
end.
Fig. 2.159: Using a feature via the public network
Note:
With the overflow procedure (see "Testing overflow routing in the
PISN", page 343) calls within the PISN are routed via the public network.
In this case the conditions for networking with DSS1 apply. The ranges
of services available can be restricted for such calls.
8.1.4 Features in the up-circuit PBX
A number of features can be triggered in the up-circuit PBX using route selection.
For more details please refer to the Operating Instructions of the terminals and
the features overview of the up-circuit PBX (see also "Down-circuit connection of
a PBX with corded terminals", page 605).
