Integrated Services Digital Network

When an incoming Integrated Services Digital Network (ISDN) trunk call is
presented to a CLASS set with Calling Number Delivery active, the calling
number delivered to the CLASS set is one of the following:
•If the incoming CLID is defined as display denied (the originating set has
Display Digit Denied, Calling Party Privacy, or Calling Line Identification
Restriction active), then the calling number privacy indicator is delivered
in place of the calling number, or, if no CLID is passed in from the
incoming trunk, then the calling number unknown indicator is delivered
in place of the calling number.
•If no CLID is passed on by the incoming trunk, then the calling number
unknown indicator is delivered in place of the calling number.
•Otherwise, the CLID received from the incoming ISDN trunk is directly
delivered. If the CLID is longer than 10 digits, only the first 10 is
delivered.
When an incoming ISDN trunk call is presented to a CLASS set with Calling
Name Delivery active, the calling name delivered to the CLASS set is one
of the following:
•If the calling name is defined as presentation denied (the originating

Identification Restriction active), then the calling name privacy indicator
is delivered instead of the calling name.
•If no calling name is passed on by the incoming trunk, then the calling
name unknown indicator is delivered in place of the calling name.
•Otherwise, the calling name received from the incoming ISDN trunk is
directly delivered. If the calling name is longer than 15 characters, only
