Introduction
The Auto Callback (AC)/Auto Redial (AR) feature will not function properly if the dialed digit string is
Note
changed or translated during the call routing, such as in the table route.
The Cisco BTS 10200 Softswitch digit manipulation or digit translation function enables manipulating
or translating either the digit string, or the nature of address (NOA), or both. Digit manipulation or
translation can take place at several points in call processing, as illustrated in
Figure 1-1

(Digit and/or NOA
The digit and/or NOA manipulation rules can be applied during the pre-translations, translations, or
routing stages. Additionally, digit manipulations or digit translations can occur at either the originating
basic call system manager (OBCSM) or the terminating basic call system manager (TBCSM). The
following sections describe the tables and tokens required for digit and/or NOA manipulation at each of
these three stages. For details on routing and call processing including actions at specific points in call
processing, refer to
Pre-Translations—In the pre-translations stage, the dial-plan-profile table is used to specify if
automatic number identification (ANI), dialed number identification service (DNIS) or both are to be
manipulated. The purpose of pre-translation stage is to normalize the digits as required during the
translations stage. For example: if a region supports 7-digit dialing, you can us DNIS manipulation in
the dial-plan-profile to add an home numbering plan area (HNPA) to make it a 10-digit directory number
(DN).
Translations—The dial-plan table can be used to manipulate the called party number (DNIS). Simple
delete/prefix functionality is supported.
