Interpreting Event data 2 cause value information

Last Updated : Oct 07, 2020 |

About this task

To interpret Event data 2 cause value information, look at the example given in Event data 2.

Event Data 2 value, 0x429, includes the following information:

  • Cause Value 0x29.

  • Location Code 0x4.

  • Diagnostic Code 0x00 (not provided for this denial event).

Procedure

  1. Convert the hexadecimal number provided in Event Data 2 to three binary numbers.

    Each binary number consists of eight bits. See Event data 2 conversion example for an example of the hexadecimal number 0x429, and .Hexadecimal, decimal, and binary equivalents for the binary equivalents for individual digits.

  2. Add up the decimal weights that have a 1 for each of the 8-bit segments.

    • Convert Cause Value 0x29 to decimal and calculate the total.

      Cause Value (Bits 1 - 8): 1 +8 + 32 = 41. This is Cause Value 41.

    • Convert Location Code 0x4 to decimal and calculate the total.

      Location Code (Bits 9 - 16): 4 = 4. This is Location Code 4.

    • Convert Diagnostic Value 0x00 (Bits 17 - 24): 0 = 0.

      Diagnostic Code is 0, not provided for this example denial event.

  3. Use the information to explain of the Event Data 2 information.

    • Cause Value 41 = Temporary Failure. See Cause values.

    • Location Code 4 = Remote Network/Public Network Serving Remote User (the Local Exchange Carrier at the far end of the call). See Location codes.
