CIS ANI Reception Page 1071 of 3156
Features and Services
• They are mapped into the Multi-frequency Compelled Signaling
complying with CCITT R2 specification (R2MFC) Calling Number
Identification R2MFC (CNI)
• They are displayed on the display of the Meridian 1 proprietary sets and
on the attendant consoles
• They are stored in the Call Detail Recorder
• They are sent through the Meridian Link and the ICCM link using the
fields dedicated for the R2MFC CNI digits
The translation of the dialed number which is received from the CIS CO
is postponed until the CDTI2 card informs Meridian 1 that the ANI digits
have been received. If the ANI reception report does not arrive from the
card, the call is treated after the ANI timer expires. The treatment for the
call that failed to provide the automatic ANI is configured on the route
data block level.
Solicited ANI request
The solicited ANI request is issued upon a manual request from the
Meridian 1 proprietary set using the display key or from the attendant console
using the trace key. The received ANI information is displayed on the display
of the Meridian 1 proprietary set or attendant console and it is also used for
the CDR, call trace. If the request is performed using the Trace key, the MCT
record is printed also on the MCT TTY. Meridian 1 sends the ANI request
message to the CDTI2 card when a user presses the DN key after the set has
entered display mode using the Digit Display key or after the Trace key was
pressed. The CDTI2 card performs the ANI interaction and uploads the
received ANI to the Meridian 1 (see Figure 21).
The ANI is stored in the unprotected trunk data block. The solicited ANI
request may be performed an unlimited number of times during a single call.
Each time, the new ANI replaces the previously received ANI (if there is
one).
When solicited ANI request is initiated using the Trace key, the Malicious
Call Trace feature functionality remains unchanged, the ANI request is sent
in addition to the normal MCT activities. The ANI information, when
received from the card, is also printed on the MCT TTY as MCT ticket.
