Explanation
The Enhanced 911 (E911) subsystem generates E911209. The E911 generates E911209 when the system rejects an Automatic Location Identification (ALI) record transmission from the tandem to the ALI.
Format
The log report format for E911209 is as follows:
E911209 mmmdd hh:mm:ss ssdd FAILURE TO SEND ALI RECORD PSAPNUM <aa> POSNUM <aa> MPC <aa> MPCLINK <aa>
Example
An example of log report E911209 follows:
E911209 FEB03 13:05:24 0101 FAILURE TO SEND ALI RECORD PSAPNUM 3 POSNUM 12 MPC 1 MPCLINK 3
Field Descriptions
The following table describes each field in the log report:
-----------------------------------------------------------------------------------------
Field Value Description
-----------------------------------------------------------------------------------------
FAILURE TO SEND Constant Indicates a rejected ALI record transmission
ALI RECORD from the tandem to the ALI system.
-----------------------------------------------------------------------------------------
PSAPNUM 0 to 999 Indicates PSAP number and corresponds to the
or Not Applicable "NA" entries in the ALI system computer.
-----------------------------------------------------------------------------------------
POSNUM 0 to 99 Indicates a different number within the PSAP
or Not Applicable "NA" that identifies the position that receives the
ALI.
-----------------------------------------------------------------------------------------
MPC Integers Identifies the number in table MPC that applies
or Not Applicable "NA" to the Multi-Protocol Controller (MPC) card in
use.
-----------------------------------------------------------------------------------------
MPCLINK Integers Indicates one entry in table MPCLINK for each
or Not Applicable "NA" data link connected to the ALI system.
-----------------------------------------------------------------------------------------

Action
When there are a number of these logs, check the accuracy of the data link between the MPC card and the ALI controller. Also, check the entries in the DMS and ALI systems.
