CG-IEIK-001 Issue 4-August 1, 2005

The TN database contains all the out-dial subscriber lines within the exchanges in the county / city / parish. This information includes the individual telephone number, name, address, location (apartment, lot, etc.) and class and type of service. The TN database is necessary to support the ALI retrieval to be displayed at the PSAP.

It is initially created from an extract of customer account data by each Telco, then processed against the MSAG. All subscriber lines find an exact match and are assigned the appropriate ESN. Any discrepancies will be resolved by the Telco and the County / City / Parish.

The TN database is updated by processing daily service orders against the MSAG. Options for providing this data to INTRADO is explained in detail later in this document.
