Nortel Networks NN43001-106 Date and time stamp information, Calling number information

Feature description 497

name information (see the "Calling name information" (page 498) section

on "Calling name information" (page 498)) per the Bellcore CLASS CND

delivery standard.

To activate both Calling Number Delivery and Calling Name Delivery, the

station set is to be conﬁgured with both the CLASS Calling Number Multiple

Data Message Format Allow (CNUA) and the CLASS Calling Name Multiple

Data Message Format Allow (CNAA) class of service. Subsequently,

whenever a call is presented to that set, the system software will deliver the

date and time stamp information, the calling number information, and the

calling name information, per the Bellcore CLASS CND delivery standard.

Date and time stamp information

The date and time stamp information delivered to a CLASS set is in the

format mm dd hh mm, where mm is a two-digit number for the month, dd

is a two-digit number for the day of the month, hh is a two-digit number for

the military hour of the day, and mm is a two-digit number for the minute

of the hour. It is up to the CLASS set to display the date and time stamp

information.

For a non-ISDN trunk-to-CLASS set call, the calling number delivered to the

CLASS set is the incoming In-Band ANI, or if no ANI is passed on, then the

calling number unknown indicator is delivered in place of the calling number.

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.

For an ISDN trunk-to-CLASS set call, the calling number delivered to the

CLASS set is the CLID received from the incoming ISDN trunk (if the CLID

is longer than 10 digits, only the ﬁrst 10 is 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 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.

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.

For a station (set)-to-CLASS set call, the calling number delivered to the

CLASS set is one of the following:

•If the originating set has Display Digit Denied active (CLS = DDGD in

LD 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 LD 15), then the originating

DN is delivered.
