Automatic Number Identification/Dialed Number Identification
Service Manipulation
The Cisco BTS 10200 Softswitch supports DNIS or ANI digit manipulation, it includes digit
manipulation or nature of address manipulation or both. When ANI manipulation is defined, it usually
refers to the calling party number (CPN) which is normally displayed when a call is terminated to a
device with calling number delivery (CND) feature.
In countries like China, there are additional requirements regarding ANI display. The requirements are
to display ANI in the "dialable" format. The term dialable means the user can simply call up the display
and hit the dial button to place the call based on the received ANI. This requires ANI to contain an area
code or national destination code (NDC) for a long distance call while only displaying subscriber
number for a local call. The rules defined above can be used to manipulate ANI digits to the desired
format.
When call forwarding has occurred, the ANI manipulation is performed as follows:
•
•
•
The following sections describe the provisioning and actions in each of the three stages in greater detail.

Pre-Translation Stage

In the pre-translations stage, the dial-plan-profile table is used to specify if ANI, DNIS, or both are to
be manipulated. The purpose of the pre-translation stage is to normalize the digits, as required, during
the translations stage.
In addition to manipulating the ANI/DNIS digits, the pre-translation stage can also be used to determine
the NOA of the incoming digits (either ANI or DNIS or both).
The Dial Plan Profile table has been modified to allow provisioning of the ANI and DNIS digit
manipulation rules.
Example 1:
In the first example, since the first character of the input string matches the specified match-string (^*),
the NOA is changed to a vertical service code (VSC).
Add digman id=pretrans; rule=1; match-string=^*; replace-string=&; match-noa=any;
replace-noa=vsc;
Enter input string *55#
Match string ^*
Replace string &
MATCHED
Output string = *55#

If redirecting party number is available, the redirecting party number is manipulated.
If redirecting party number is not available, but original called number (OCN) is available, the OCN
is manipulated.
If neither redirecting party number nor OCN are available, then the calling party number is
manipulated.
