Programming
Enable COS Option 800 (ANI Applies) for the trunk.
Enable Circuit Descriptor option "Far End Gives Supervision" for the trunk.
The Circuit Descriptor option "DTMF" for the trunk must match the far end.
Operation
When a call is made on an ANI trunk, an answer supervision received on
the ANI trunk is treated as a signal to send the calling party's extension
number. During transmission of the calling extension number, the calling
party is not connected to the speech path. This inhibits putting any noise
(that could be mistaken for DTMF signalling) onto the line until all dialing
is finished. Once the extension number has been sent, the calling party's
audio will be cut through and no further signalling will occur.
Automatic Number Identification (ANI)/
Dialed Number Identification Service (DNIS) on Incoming Trunks
Description
This feature allows the PABX to identify Automatic Number Identification
(ANI) numbers and Dialed Number Identification Service (DNIS) numbers
that are transmitted to the PABX on an incoming trunk. ANI provides the
telephone number of the calling party; DNIS provides the telephone num-
ber dialed by the calling party.
The SX-ZOO DIGITAL PABX can receive ANI and DNIS numbers on specific
types of incoming non-DISA trunks. After receiving ANI and DNIS numbers
for an incoming call, the SX-200DIGlTAL PABXcan then makethe numbers
available to other functions within the system. You can program the SX-200
DIGITAL PABX to provide ANI and DNIS numbers to SUPERSETdisplay
telephones, to SUPERSETconsoles, to SMDR printers, and to application
platform packages.
On a SUPERSETconsole, the ANI and DNIS digits for an incoming call are
displayed after the call is answered. The ANI digits appear where the trunk
information is normally displayed; the DNIS digits overwrite the COS and
COR fields on the console display. When ANI digits are not received, the
trunk information is shown instead; when DNIS digits are not received, the
COS and COR fields are visible. By default, ANI and DNIS numbers are not
displayed.
On SUPERSETdisplay telephones, the display shows DNIS digits while the
call is unanswered. After the user answers the call, the ANI digits are
displayed. Whenever ANI digits are not available for a call, the display shows
the DNIS digits during both the unanswered and answered states.
Whenever DNIS digits are not available, the display shows the ANI digits
during both the unanswered and answered states. If neither are available,
the display shows the normal trunk information. By default, ANI and DNIS
numbers are not displayed.
