Automatic Number Identification Delivery
Description:
Automatic Number Identification is a service feature for both E&M and DID lines.
Long distance common carriers offer as a feature to dial $00 and dial 900 lines. The
feature provides information to an internal telephone system that identifies the telephone
number of the calling party. Businesses served by a dial 800 or dial 900 service allow any
available user to answer the calls and have their internal telephone system process the
information to identify the caller’s telephone number.
The common carrier supplies information as digits. When the feature
is
combined with the Dialed Number Identification Service (DNIS) feature, the common carrier
also delimits the DNIS information from the information with an asterisk tone so that
the DXP can process each portion properly.
The DXP
Plus
system decodes the AN1 information and sends the caller’s number to the called
telephone and to the line reports. If the called telephone is an LCD
speakerphone, its display shows the caller’s number. This display is shown for all conditions
(that is, transferred calls, call forward and so forth). The DXP
Plus
also sends the calling
number information to the line report and makes the information available to
devices that are connected to the DXP Plus’s Architecture Interface
When you assign to lines that callers reach by access codes, the
processes all incoming digits as AN1 digits until it encounters the delimiter. The
Plus
then
processes the remainder of the incoming digits as DNIS call routing digits. When you assign
to lines that callers reach without dialing any digits (such as, E&M hot line or DID lines
with 0 digits expected), the DXP
Plus
processes all incoming digits as digits until it
encounters the end delimiter. The DXP
Plus
then routes the call to one of the followingintercom
numbers: the one that services the E&M hot line number, the one that serves as the
default, or the one that serves as the operator for the system.
The DID, E&M DNIS, and E&M tie lines all can access the Direct Inward System Access
(DISA) feature when the caller dials the DISA access code or when the digits
translate to the DISA access code. The system distinguishes the DISA code from the preceding
AN1 information.
Since the DXP
Plus
supports AN1 only on tone dial lines, is supports both wink start and delay
start protocols but does not support the immediate start protocol.
