446 CIS ANI Digits Manipulation and Gateways Enhancements
ANI is sent on the following CIS trunks on the system:
CIS three-wire analog trunk
CIS digital trunk interface Dial Pulse (DP) and Multi-Frequency Shuttle
(MFS)

Shared functionality

When configuring outgoing CIS routes, the feature is activated using the
prompt ANIC to enable composition of a new ANI.
Two similar ANI tables are configured in the customer data block. One is
used when call is originated from a set. The second table is used when call
is originated from a route.
Up to 2000 entries can be configured in the ANI table for sets. Up to 512
entries can be configured in the ANI table for routes.
An ANI entry contains the following data:
DNLG (DN Length): it gives the number of digits of the calling number
that is used for building the ANI DN (for example calling party DN =
342390 and DNLG = 4 will give an ANI DN = 2390).
LEC: Local Exchange Code.
ANDN: used as ANI DN if DNLG=0.
ADDG: additional digits.

CIS ANI Digits Manipulation introduction

The CIS ANI Digits Manipulation feature enhances the system CIS ANI
digits manipulation capabilities by increasing flexibility and ensuring greater
