The Calling Name Access Routing Guide (CNARG) is a single source of information for accessing information relative to databases containing subscriber Calling Name information. CNARG data is used to help administer and maintain Global Title Translation (GTT) tables within Signal Transfer Points (STPs). These tables direct signaling traffic to the correct network locations that store Calling Name data, used to display the caller’s name during incoming calls. The CNARG’s format and content are similar to the LIDB Access Routing Guide (LARG) which is used to manage access for database queries relative to alternate billing services information.

A text file that defines data fields, provides contact information, etc., is provided with each issue.

The CNARG is a valuable resource for:

• Calling Name service providers
• Database maintenance staff
• Service providers and database maintenance staff who need access to calling name information in order to provide calling party’s name to end users

Benefits of the CNARG:

• Increasing the accuracy of queries
• Improving GTT performance
• A complete source of data to populate global title translation tables within the STP that will save staff time and money
  Increase accuracy of data
