data records, the location data field may beused to define the cell site sector geographical servicearea.
WirelessCarriers should work with theE911 Customerand agree on the TN data record formats including
use of the LOCATION(LOC) data field.
There are four(4) levelsof identifiers used for different types of information. Those identifiers are shown
as follows in the appropriate hierarchical level:
Level 1: BLDG, WNG, PIER
Level 2: FLR
Level 3: APT, RM, LOT,SLIP, SUIT, UNIT
Level 4: DES
These identifiers may be used uniquely or combined. The identifiers and associated data cannot exceed the
size limitation of the data field. Some examples are shown below:
EXAMPLE 1: APT 2-B
EXAMPLE 2: BLDG 6 APT 2-B
EXAMPLE 3: FLR 6 SUIT 2-B
EXAMPLE 4: DES NEXT TO POOL
EXAMPLE 5: .25 MI NE OF MAIN ST (wireless example)
5.9 Updating the TN Database
The Wireless Carrier must provide data records for the E911 database as described in this tab. Data
records are validated for proper format and to ensure the address information is defined in the MSAG
database. The TN data record includes a "Function of Change" data field to indicate the type of processing
that should be performed forthis record. Processing rules for some of the "Function of Change" data
values are described below:
Function of Change
Data Value: Processing Rules:
IInsert this data record into the database. There must not be another data
record with the same TN (pANI) or calling number in the database or the
insert will fail.
C Change the corresponding record in the database. A data record must
already existin thedatabase with the same TN (pANI) orcalling number.
The entire database record is replaced by the new data record, therefore
the incoming record must have all appropriate data fields populated.
DDelete the corresponding record in the database. A data record must
already existin thedatabase with the same TN (pANI) orcalling number.
EDelete the corresponding record in the Error File. No processing is
performed against the E911 database.
