The Calling Name Access Routing Guide (CNARG) is a single source of information for accessing information relative to databases containing subscriber Calling Name information. The CNARG data can be used to administer and maintain Signal Transfer Point (STP) Global Title Translations (GTT) tables used to route to points that contain this data. The CNARG’s format and content is similar to the LIDB Access Routing Guide (LARG) that is used to manage access for database queries relative to alternate billing services information.

The Calling Name Access Routing Guide is a useful tool for:

• Calling Name service providers
• Database maintenance staff
• Increasing accuracy of queries
• Improving GTT performance

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