Page 1100 of 3156 CLASS: Calling Number and Name Delivery
553-3001-306 Standard 10.00 January 2002
Calling number information
For a non-ISDN trunk-to-CLASS set call, the calling number delivered to the
CLASS set will be the incoming In-Band ANI, or if no ANI is passed on, then
the calling number unknown indicator
1
is delivered in place of the calling
number.
For an ISDN trunk-to-CLASS set call, the calling number delivered to the
CLASS set will be the CLID received from the incoming ISDN trunk (if the
CLID is longer than 10 digits, only the first 10 will be delivered). 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
2
is delivered
instead of the calling number, or, if no CLID is passed on by the incoming
trunk, then the calling number unknown indicator is delivered in place of the
calling number.
For a station (set)-to-CLASS set call, the calling number delivered to the
CLASS set will be one of the following:
• If the originating set has Display Digit Denied active (CLS=DDGD in
Overlay 10 or 11), then the calling number privacy indicator is delivered
in place of the calling number.
• If the CLID entry of the originating DN specifies that it is to be identified
by its internal DN (CLASS_FMT=DN in Overlay 15), then the
originating DN is delivered.
• If the CLID entry of the originating DN specifies that it is to be identified
by its local number (CLASS_FMT=LCL in Overlay 15), then the local
public number associated with the originating DN
3
is delivered, (if the
CLID is longer than 10 digits, only the first 10 will be delivered).
1.The calling number unknown indicator, per Bellcore CLASS CND delivery standard, refers to the
ASCII “O” that is sent in place of the calling number.
2.The calling number privacy indicator, per Bellcore CLASS CND delivery standard, refers to the ASCII “P”
that is sent in place of the calling number.
3.The local public number is composed by the ISDN CLID Enhancements feature, which forms the calling
number by concatenating the customer defined home local number (HLCL in Overlay 15) and the originating
DN.
