474 CIS ANI Reception
the attendant console. The request to receive the ANI information is
invoked by pressing a calling number display key on the attendant
console source key or on the proprietary set by pressing the display key
followed by the trace key. Press trace key for active call for Proprietary
sets and attendant consoles. The trace key can be used instead of the
source key for Malicious Call Trace (MCT) for sets and consoles. An ANI
request can also be made by 500/2500 sets by entering the Flexible
Feature Code (FFC) assigned for MTRC in LD 57.

Automatic ANI request

The automatic ANI request is sent by the CDTI2 card to the CIS CO before
the incoming local call is answered. If the incoming trunk operates in the
decadic, or Dial Pulse (DP) mode, the ANI request is sent to the CIS CO
after all dialed digits have been collected from the CIS CO (see Figure 6
"Automatic ANI request for incoming local call (decadic dial pulse mode)"
(page 476)). If the trunk operates in the MF Shuttle mode, the ANI request
is sent after the end of the MF Shuttle dialing (see Figure 7 "Automatic
ANI request for the MF shuttle call" (page 477) on Figure 7 "Automatic ANI
request for the MF shuttle call" (page 477)). The ANI digits are uploaded to
the system.
The Automatic ANI request option may be used only in conjunction with the
DN Size Feature. The DN Size Flexible (using the SSL tables) or Fixed
should be defined for the incoming CIS DTI2 DID route before setting the
automatic ANI option to "Yes".
The ANI digits are used in the following way:
•They are tandemed as the Calling Line Identification (CLID) Originating
Line Identifier on DPNSS (OLI) to the (ISDN) Integrated Services Digital
Network/Digital Private Network Signalling System (DPNSS) gateways,
Basic Rate Interface (BRI) gateways
•They are mapped into the Multifrequency Compelled Signaling
complying with CCITT R2 specification (R2MFC) Calling Number
Identification R2MFC (CNI)
•They are displayed on the display of the 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 the system 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.
