Now that you have configured 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.

It is possible to create multiple GTT associations. This allows, for example, having 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)
