Setting up a Virtual Subscriber
A PISN subscriber is set up for this purpose (see "Numbering Plan", page 199).
Enter the public network subscriber's full number under Number" For outgoing
calls the configured number will be dialled via the configured route instead of the
dialled PISN subscriber number. This mechanism is similar to the one used for
abbreviated dialling.
When the subscriber calls up from the public network, his CLIP number will be
compared with the numbers of all the PISN subscribers. If there is a match, the
called subscriber is shown the PISN subscriber number by way of CLIP instead of
the CLIP sent from the public network.
3.5 Display for Call Forwarding Unconditional
When Call Forwarding Unconditional is activated, it is useful for subscribers to
know that the call was redirected, by whom and to whom. This means the called
subscriber is able to answer the call on behalf of the subscriber who redirected
the call to him. With this information the calling subscriber is better prepared for
the call. This redirecting information is available on system terminals and ISDN ter-
minals both internally and in private networks. If the public network operator sup-
ports the function, the redirecting information is also available to virtual PISN sub-
scribers and subscribers in the public network.
3.5.1 Information displayed to the called subscriber
The called subscriber sees not only the caller's name and number but also that the
call was redirected and who redirected it (redirecting information).
Example:
Subscriber A calls subscriber B, who has redirected to subscriber C. The display on
an Office 45 system terminal at subscriber C reads:
<CNIP A> / <CLIP A> forwarded from <CNIP B> / <CLIP B>
This redirecting information at subscriber C is available for "CFU", "CFB",
"CFNR" and "Call Deflection (CD)". (With CD "forwarded from" is displayed
instead of "Deflected from".)
