Creating an SCCP GTT Association

This article applies to:	Product	Version
	Tmedia	2.9, 2.10, 3.0, 3.2

After you create an SCCP SSN, you must create a new SCCP Global Title Translation Association.

SCCP GTT Association A GTT association defines a particular Global Title format and associated fields. It is assumed that all global titles included in this association have specific translation needs and therefore can be served by a single translation function set.

You can create multiple GTT associations. This allows, for example, you to have a separate "Translation Table" for different Numbering Plan, E.164 vs E.212.

The GTT Association is the association between:

Inbound SCCP Network(s)
A set of filtering rules on GTI,TT,NAI,NP,ES values
A Global Title Translation table

Filtering Rules Inbound SCCP messages that matches all filter following criteria will hit the associated "Translation Table"

Creating an SCCP GTT Association

1- Select SCCP from the navigation panel

2- Click Create New Sccp GTT Association from the SCCP stack configuration window

3- Configure the new SCCP GTT association:

Enter a Name for the new GTT association
Select a Protocol Variant
Select an SCCP Network to bind to this GTT Association
Select a Format Type (GTI)

4- Depending on Format Type, select if you want to filter on GT following parameters. Below example shows the applicable fields for Format Type = "Type_4":

5- Click Create

6- Verify that the "SccpGTTAsso was successfully created" message appears
