326 Calling Party Privacy Override
Non-ISDN to ISDN tandem Even though a Privacy Override Indicator
is not provided for an incoming non-ISDN trunk call, if the outgoing route
has TCPP set to NO, the Presentation Indicator field in the Calling Party
IE is set to "Presentation Allowed".
Non-ISDN to non-ISDN tandem A Privacy Override Indicator is not
provided for an incoming non-ISDN trunk call. If the outgoing route has
TCPP set to NO, the Privacy Override Indicator defined for that route is
outpulsed, provided that the outgoing route provisions CPPO.
Operating parameters
Central Office Trunks (COT), Foreign Exchange (FEX), Wide Area
Telephone Service (WATS), and Direct Inward Dial (DID) are the only trunk
route types (including ISA service routes) that can out-pulse the Privacy
Override Indicator for an outgoing non-ISDN call. All ISDN trunk routes
provision the CPPO feature.
A non-ISDN trunk route does not provision the CPPO feature if the out-pulse
asterisk and Octothorpe (OPAO) package (package 104) is configured.
During SYSLOAD, the CPPO database is removed from the non-ISDN trunk
routes if the OPAO package is configured.
The Privacy Override Indicator, defined for a non-ISDN trunk route
(dial-pulse or digitone), consists of any four arbitrary digits from 0-9. The
asterisk (*) or octothorpe (#) cannot be part of the Privacy Override Indicator
for dial-pulse trunks. For digitone trunks, the asterisk (*) can only be the first
digit of the Privacy Override Indicator Flexible Feature Code.
The asterisk and octothorpe are not outpulsed if the OPAO package is
configured. The asterisk signals a three second pause and the octothorpe
indicates end-of-dialing. The octothorpe cannot be used in a Privacy
Override Indicator.
The asterisk (*) used to introduce a pause while out-pulsing digits is
supported on analog and DTI trunks, but not supported on ISDN trunks. On
ISDN trunks, if the OPAO feature is enabled, the asterisk (*) is outpulsed
as a called party digit.
Privacy Override Indicators are not received from the CO or non-ISDN
DID trunks.
The CPPO Flexible Feature Code cannot conflict with any internal DN,
including the Special Prefix (SPRE) code.
