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

A portion of the TN data record layout includes a twenty(20) character field for specific location information. This field is not edited for content, however, there are certain format standards that the PSAP customer is accustomed to viewing on the incoming call.

There are three(3) levels of identifiers used for different types of information. Those identifiers are shown as follows in the appropriate hierarchical level:

These identifiers may be used uniquely or combined. The identifiers and associated data cannot exceed the twenty(20) character size limitation. Some examples are shown below:

Example:

APT 2-B

Example:

BLDG 6 APT 2-B

Example:

FLR 6 SUIT 2-B

If the existing TN record contains location information and the data is not changing, the incoming update for that TN must recap the location information. If the location data is not recapped on the incoming update being processed, it is assumed that the existing location data is to be removed and the current update will overwrite the existing record to remove the data.
