> GT-Format4 Configuration Mode Commands
> The GT-Format4 configuration mode is a sub-mode for either the Global Title Translation Association configuration mode or the Global Title Translation Address-Map configuration mode. This sub-mode configures a set of rules used in the global title translation (GTT) process.
> Upon accessing this mode, your prompt should look similar to the following:
> [local]<hostname>(config-gtt-1-format<#>)#
> Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
> encoding-scheme
> Configures the encoding-scheme to use during GTT.

> Syntax
> encoding scheme scheme_type
> scheme_type
> Select one of the following encoding scheme types to determine the encoding type to be used during GTT:

> • | bcd-even: BCD even encoding scheme

> • | bcd-odd: BCD odd encoding scheme

> • | nw-specfic: Network-specific encoding scheme

> • | unknown: Unknown encoding scheme

> Usage
> Select BCD even encoding for GTT
> Example
> encoding scheme bcd-even

> nature-of-address
> Configures the indicator to identify the nature of the address.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> nature-of-address { international | national | subscriber )
> international
> Identifies the numbers as international.
> national
> Identifies the numbers as matching the national configuration.
> subscriber
> Identifies the numbers as subscriber numbers.
> Usage
> Configure the identify of the GT format as national.
> Example
> nature-or-address national
> numbering-plan
> Configures the GTT process to apply one of the numbering-plans during the GT translation process.
> Product

> • | isdn : ISDN tel numbering plan

> • | isdn-mobile: ISDN mobile numbering plan

> • | land-mobile: Land mobile numbering plan

> • | maritime-mobile: Maritime mobile numbering plan

> • | nw-specific : Private network/ network-specific numbering plan

> • | telex: Telex numbering plan

> • | unknown: Unknown numbering plan

> Usage
> Select ISN telephone number plan for GTT process.
> Example

> Privilege
> Security Administrator, Administrator
> Syntax
> translation-type number
> number
> Must be an integer between 0 and 255.
> Default is 0.
> Usage
