Calling Party Privacy

The Calling Party Privacy (CPP) feature enables the system to support the

blocking of a Calling Party's Number and Name from being displayed at the

terminating set on an individual call basis. Users can dial a Calling Party

Privacy code (for example, *67 from a proprietary set or 1167 from an analog

(500/2500 type) set) to prevent their telephone number and name from being

displayed on a receiving telephone across the Public Switched Telephone

Network (PSTN). Internal calls within the system have originating numbers

or names displayed, even though the originating call has requested privacy.

This feature also allows a per-line blocking Class of Service to be

programmed for station sets for public network calls. This relieves the user

from having to dial the Flexible Feature Code (FFC) for every call, but in

every other way is equivalent to the per-call blocking.

Please refer to ISDN Primary Rate Interface Fundamentals (NN43001-569)

for complete information.
