Feature description
This document covers the Commonwealth of Independent States (CIS)
Automatic Number Identification (ANI) Digits Manipulation and Gateways
Enhancements features. It describes pre-release 24 operation and explains
how each feature is enhanced in Release 24. The features are presented
together because they share many common characteristics.
CIS ANI Digits Manipulation and Gateways Enhancements features allow
the ANI to be built in a more flexible way when the call is originated from a
set and from a route.
ANI Definition
The Automatic Number Identification (ANI) information is a string of digits
sent to the Central Office (CO), which it uses to identify the calling subscriber
for billing purposes, Malicious Call Trace (MCT) purposes, and for
immediate information about the subscriber when reaching some vital service
such as fire brigade, emergency medical care, or law enforcement officials.
The ANI information is sent over the speech path whenever the CO
requests it.
On Meridian 1, ANI is sent on the following CIS trunks:
• CIS three-wire analog trunk
• CIS digital trunk interface Dial Pulse (DP) and Multi-Frequency Shuttle
(MFS)
• Before Release 24, the ANI is a sequence of eight digits composed of:
• The number the user will be billed to. It consists of three digits for the
CO local exchange code (LEC) to which the PBX is connected + four
digits for the subscriber number (ANI DN).
• The 1-digit-long subscriber category (CAC), which gives the level of
services the user can obtain.
