Flexible ANI Information Digits

The flexible ANI information digit assignment feature permits the association
of supplementary information digits with specific calling party classes of
service (e.g., coin phone, hotel/motel, and prison service).  The purpose of
flexible ANI information digits is to provide information about the calling
party's directory number which may be useful to ESPs for billing and/or
screening of calls.  Flexible ANI information digit assignments are made by
Bellcore as part of its North American Number Plan administration 
responsibilities.

FEATURE OPERATION:

Flexible ANI applies to interoffice calls that send two digit ANI information
via Equal Access Multi-Frequency Signaling, InterLATA Common Channel Signaling
or Modified Operator Services Signaling.  When Flexible ANI digits apply to a
class of service, they will be outpulsed instead of hard-coded class of service
ANI pairs.  Being able to associate flexible ANI pairs to originating line 
class of service translations provides the capability for the terminating 
switch to identify more classes of lines.  In addition, associating flexible
ANI pairs with the routing translations for ESP services provides an efficient
method for ESPs to identify when customers are attempting to use those 
services.  The ANI pairs are transmitted as part of the ANI signaling sequence
and are used by the receiving switch to identify the type of originating line
or the type of call being made.

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:

1. This feature is available in the following central office switches:

Switch Type			1A ESS		5ESS	DMS-100
Earliest Generic Release	1AE8A.17	5E6	BCS27

2. The Circuit Switched Trunk type BSA with FG D in-band signaling interface 
   will support this BSE.  It can be supported via either a direct or tandem
   trunk arrangement.

3. Flexible ANI can only be assigned to the Circuit Switched Trunk type BSA that
   has the Calling Billing Number Delivery (ANI) BSE assigned as an option.
