Call to a PISN Subscriber
The creation of the CLIP number depends on the configured PISN subscriber. If
the PISN subscriber has "CLIP selection = normal", the DDI number is used as
CLIP, providing the subscriber is himself reachable by incoming calls via the path
trunk group → direct dialling plan → CDE.
If there is no direct dialling plan or corresponding DDI number (which is normally
the case), the subscriber's internal call number is used instead.
If the subscriber has the setting "CLIP selection = SC CLIP", the CLIP number is
created in the same way as for a call to the public network. This means that a per-
manently defined CLIP number can also be transmitted in the private network.
Call with Route Selection via Trunk Group with "Network Type = Private"
By analogy with the call to a PISN subscriber with the setting "CLIP selection =
normal".
PISN Subscriber
"Number" Setting
The call number entered under "Number" is compared with the CLIP number of
an incoming call. If the two numbers match up, the PISN subscriber number is dis-
played as the CLIP, with "NPI = private" and "TON = level 0".
"CLIP Selection" Setting
See "Call to a PISN Subscriber", page 197.
Trunk groups
"NPI unknown Call" Setting
If a call with "NPI = unknown" is received, it is signalled with the internal or exter-
nal ringing pattern on the basis of this setting. It is also decided at the same time
whether the exchange access prefix (0-) should precede the CLIP number.
