420 Automatic Number Identification
Feature interactions
Directory Number Expansion
If the DN Expansion package is equipped, the ANI billing number (ANAT)
can have up to seven digits. The total number of digits for ANAT and ANI
listed DN (ANLD) cannot exceed seven.
INIT ACD Queue Call Restore
Restored calls do not retain ANI information, unless the call was an
incoming call on an M911 trunk.
M911
The Meridian 911 permits special treatment for emergency calls. This
feature requires the QPC916 MF receiver card. For more information about
this card, see Feature Group D description and operation.
Valid Automatic Number Identification combinations
When the system receives a call from a 911 trunk, the trunk receives the
ANI information through MF signaling from the Central Office. A valid ANI,
received through 911, includes a 1-digit NPD or ID digit followed by a 7-digit
calling number. The NPD or identification digit can be displayed directly
on the answering telephone display or can be translated to a Numbering
Plan Area (NPA) using the Numbering Plan Identification (NPID) translation
table in LD 16.
The following are valid ANI digit combinations:
• KP A NXX-XXX ST (where A= the NPD, which can be 0–9);
• KP I NXX XXX ST (where I = an information digit, which can be 0–9;)
• KP I ST (where I = the information digit for ANI failure or Operator
Number Identification (ONI). ANI failure is usually designated by a 2
and ONI by a 1); and
• KP A ST (where A denotes maintenance testing, typically the digit 8).
If only one digit is received and that digit is defined in the NPID table as
TEST or FAIL, the call is treated as a test case or a call with ANI failure.
