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

A No Record Found (NRF) condition occurs when a subscriber calls 911 and the system is unable to retrieve the database information or no information exists. The purpose of a NRF investigation is to:

• identify the reason a NRF occurred
• take corrective action to update the database, as necessary

There are several reasons a record may not be available for retrieval:

• the record may be in an Error File
• the record may be "in the pipeline", between the time the subscriber has dial tone and the time the record is processed and entered into the database
• the record may have never made it to the E911 database

A primary ALI processor and a secondary ALI processor serve each PSAP in the region. These processors alternate responses to ALI retrieval requests coming from the PSAP. Therefore, audit data, including NRF data, is found on the audit files from both the primary and secondary ALI processors. This data is combined to produce one NRF report.

The NRF report will be generated every day, Monday through Friday. This report provides information about NRFs for investigation.

The following schedule has been developed for the daily NRF reports. The NRF report will be mailed/faxed daily (Monday - Friday) to the appropriate TELCO.
