Calling Party Privacy
In current operations, if the International Supplementary Features (SUPP)
package 131 is not equipped in the system, an incoming ISDN call with
the Call Party Name Display (CPND) Indicator field set to "Presentation
Denied" still displays the Calling Party Name. If package 131 is equipped
in the system, the current operations will inhibit the Calling Party Name for
an incoming ISDN call with the CPND Indicator field set to "Presentation
Denied".
The CPP feature will inhibit the display of the Calling Party Name for an
incoming ISDN call with the CPND Indicator field set to "Presentation
Denied" if package 131 is not equipped.

Centralized Attendant Service (CAS)

When an attendant in the CAS mode extends a call to a remote station, the
display shows only the source line.
Conference
When pressed during an active call, or to set up a conference, the
Conference, Connect, or Join Parties key clears the display. The telephones
involved in the conference have blank displays. If the conference returns
to a two-way only call, each telephone displays the DN and name of the
other telephone.
Dial Intercom
The display on telephones connected by Dial Intercom shows the group
member’s DIG number plus CPND information.

Dialed Number Identification Service

If an incoming trunk call from a route with Dialed Number Identification
Service (DNIS) is presented to a display telephone, the identification digits
follow the regular trunk access code and member number. It precedes the
CPND name for the DNIS incoming trunk group.

again. The original display reappears. When the telephone is inactive and
