Now that you have configured an SCCP SSN, you must create a new SCCP global title translation (GTT) 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 does the following:

• Binds a "Translation Table" to the specified SCCP Network
• Creates a set of rules that filters inbound messages on:
  • GT Indicator
  • Translation Type (TT)
  • Nature of Address Indicator (NAI)
  • Numbering Plan (NP)
  • Encoding Scheme (ES)
• Inbound SCCP messages that matches all criteria will hit the associated "Translation Table"
