Nortel Networks NN43001-106 Calling Party Privacy

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.
