Creating an SCCP GTT Association

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"
- GT Indicator
- Translation Type (TT)
- Nature of Address Indicator (NAI)
- Numbering Plan (NP)
- Encoding Scheme (ES)
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
