Users can dial a Calling Party Privacy code(e.g., *67 from a Meridian 1 proprietary set or 1167 from an analog (500/2500type) set) to prevent their telephone number and name from being displayedon a receiving telephone across the Public Switched Telephone Network(PSTN). Internal calls within the Meridian 1 will have originating numbers ornames displayed even though the originating call has requested privacy.This feature also allows a per-line blocking Class of Service to beprogrammed for station sets for public network calls. This relieves the userfrom having to dial the Flexible Feature Code (FFC) for every call, but inevery other way is equivalent to the per-call blocking.
