E.164 Esn Numbering Plan Enhancement - Nortel 1000 Features And Services Fundamentals

332 Calling Party Privacy Override
Conference
The CPPO feature passes the Privacy Override Indicator to the terminating
set in order to display the Calling Party Number and Name, if the Conference
feature is used for the purpose of performing a transfer.
Display of Calling Party Denied
When the CPP package is equipped, the CPPO feature takes precedence
over the Display of Calling Party Denied (DPD) feature for allowing the
Calling Party Number and Name to be displayed. For example, when an
outgoing ISDN call is marked as a CPPO call, then the outgoing SETUP
message includes the Calling Party Number IE with the Presentation
Indicator set to "Presentation Allowed" and the Display IE with the CPND
Indicator set to "Presentation Allowed". This enables both the Calling Party
Number and Name to be displayed on the terminating set, regardless of
whether the DPD feature allows or denies the display of the Calling Party
Number and/or Name.

E.164 ESN Numbering Plan Enhancement

CPPO can be requested for ESN calls by preceding the dialing sequence
with the Flexible Feature Code defined for the CPPO feature. The CPPO
Flexible Feature Code is counted against the maximum number of digits
(currently 31) allowed for the destination DN.
Feature Group D
When an incoming Feature Group D (FGD) call terminates at a system
locally, the received 10 digit Automatic Number Identification (ANI) is
displayed on the terminating set if the Show ANI Digits on Terminal Displays
(SHAN) field is set to YES in the FGD data block that is associated with the
incoming trunk route. If the originator requests CPPO, the end office sends
the 10 digit ANI to the circuit switched network.
If an incoming FGD call is routed to another switch through ISDN Primary
Rate Interface (PRI) or ISDN Signaling Link (ISL), the outgoing SETUP
message includes the 10 digit ANI (if it exists) as the Calling Party Number
(CLID) with the Presentation Indicator set to "Presentation Allowed". This
occurs if the incoming call requests CPPO. CPPO takes precedence over
the SHAN field that is defined in the FGD data block and is associated with
the incoming trunk route to allow the 10 digit ANI display.
Hot Line
Hot line calls carry the Privacy Override Indicator if the CPPO Flexible
Feature Code followed by the normal dialing sequence is stored in the Hot
Line DN. The CPPO Flexible Feature Code is counted against the maximum
number of digits (currently 31) allowed for the Hot Line DN.
