Cisco BTS 10200 Softswitch — Release Notes for Release 3.3 V04

OL-1835-04

New and Changed Information

Digit Manipulation Table

The Digit Manipulation (digman) table is a new table added in the Cisco BTS 10200 Softswitch in this

release to support digit manipulation. Digit manipulation was previously done in the dial plan table using

pfx_digits and del_digits, but it was available only on the called party number. With the introduction of

the digman table, the Cisco BTS 10200 Softswitch is now able to handle digit manipulation of both the

calling party and called party numbers.

The following is a brief overview of what the digman table provides for the Cisco BTS 10200 Softswitch.

Digit/NOA manipulation rules can be applied to:

• Directory Number (calling number or called number)

• Nature of Address (NOA) (calling number or called number)

• Both DN and NOA

Digit manipulation can take place at several points in call processing, including:

• Pre-translations—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.

• Translations—The dial-plan table can be used to manipulate the called party number. Simple

Delete / Prefix function is supported.

• Routing—Routing is performed in the Analyzed Info PIC (Point In Call). The destination table

and/or route table can be used to specify digit manipulation of ANI, DNIS, or both. The out-pulsing

number can be normalized using the destination table. In addition, if special manipulation is

required based on the route selected, it can be specified for each Trunk Group within a route.

If the called number terminates within the Cisco BTS 10200 Softswitch, and the subscriber number

points to a Trunk Group, then digit manipulation rules for ANI, DNIS, or both can be specified in

the Trunk Group table.

If the call is an interLATA call or requires Carrier Routing, the ANI/DNIS digit manipulation IDs

specified in the destination table are ignored and carrier based routing is performed.

Note Although pfx_digits and del_digits still work in the dial plan table, if the system supports 7-digit

dialing and the number is an LNP number, then you must put the digit manipulation in the digman

table and reference the entry from the dial plan profile table.
