Toolpack:Creating an SCCP GTT Association A

Revision as of 15:12, 1 May 2012

Now that you have configured an SCCP SSN, you must create a new SCCP global title translation (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.

In other words, 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 (1-4) value
  • Translation Type (TT)
  • Nature of Address Indicator (NAI)
  • Numbering Plan (NP)
  • Encoding Scheme (ES)
• Inbound SCCP messages that matches all criteria will hit this "Translation Table"

To Create an SCCP GTT Association:

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

2- Configure the new SCCP GTT association:

• Enter a Name for the new GTT association
