CHAPTER 4. USING THE FEATURES
Integrated Services Digital Network (lSDN)—Primary Rate
Interface (PRI) (Generic 1)
This feature provides display information in addition to the normal display information
described in Chapter 2 under “Display Area.”
The following terms are associated with ISDN-PRI display information:
• Station Identification (SID) Number: This is the 10-digit number associated with each
voice terminal. The SID number includes the area code, the office code, and the
local extension number (for example, 201-772-41 68).
• Automatic Number Identification (ANI): This is the calling party’s billing number used
by the inter-exchange carrier through Equal Access.
If the SID number is not available on an incoming ISDN call, the ANI will be displayed.
ISDN-PRI display information will be shown on the first line of the display and includes the
following:
Ž Calling Party’s Number
When an incoming ISDN-PRI call that was originated at a Generic 1 system is
received and assuming the SID was sent, the calling party’s SID number will be
displayed. On other calls, either the SID number or the AN I will be displayed. A 10-
digit number display will include a dash between the area code (if shown), the office
code, and the local number. Extension numbers and 12-digit international numbers
are displayed without dashes.
• Calling Party’s Name
When an incoming ISDN-PRI call that was originated at a Generic 1 system is
received and assuming the name was sent, the calling party’s name will be displayed.
Calls originated from the public or other private networks may not provide the calling
party’s name. If the caller’s name is not available, CALL FROM followed by the
calling party’s number will be displayed.
Ž Called Party’s Number
When a call is placed over ISDN-PRI facilities, the called number will be displayed as
it is dialed. When the call is answered, the display will show the 10-digit number of
the voice terminal where the call was answered. (This display may not be the same
number that was dialed.)
• Called Party’s Name
On incoming ISDN-PRI calls, the Generic 1 system,
if administered correctly, can
provide the called party’s name to the calling party.
The calling party’s display will
always show the name of the person who answers the call. (This display may not be
the name of the person that was actually called.)
