8. No Record Found (NRF) Processing

A No Record Found (NRF) condition occurs when a subscriber calls 911 and no database information

exists for the cell site pseudo-ANI telephone number. The purpose of an NRF investigation is to:

• identifythe reason a NRF occurred

• takecorrective action to update the database as necessary

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

• therecord may be in the Error File

• therecord may not have posted between the time the cell site has been "turned up" and the

time the record is processed and entered into the database

• theupdate SOIR file transmission may have failed to complete successfully

• therecord may not have been sent to be inserted into the database

It is imperative the Wireless Carriers ensure all appropriate pseudo-ANI records are successfully posted to

the E911 database before conducting 911 call testing or turning up service. Wireless 911 calls processed

without corresponding pseudo-ANI records in the database will result in NRFs at the PSAP and manual

investigationby the INTRADO Data Integrity Unit.

Each PSAP in the region is servedby a primary ALI processor and secondary ALI processor. These

processors alternate responses to ALI retrieval requests (bids) 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 everyday, Sunday through Saturday. This report provides information

about NRFs for investigation. NRF details will appear on the report once the appropriate carrier is

identified.

The following schedule has been developed for the generation of daily NRF reports. The NRF report will
