APPENDIX F

INTERPRETING Q.931 MESSAGE LOGGING CODES

With Q.931 message logging, you can view messages in History mode in two different formats:

Normal format

Hexadecimal format

This appendix describes these two formats in detail, showing what messages look like in each. At the back of this appendix you'll find three tables explaining the codes and abbreviations used in the messages.

Note: Softkey 1 also serves as the ENTER key (for entering information as indicated in this User Guide).

NORMAL FORMAT IN

HISTORY MODE

The normal format of the History mode shows abbreviated information. An abbreviated message and call status code are displayed for transmission and reception messages. The information element codes, selected Directory Number value, and call status code are not shown.

The screens below are examples of messages in the normal format of History mode. Note that line 4 of the displays shows the names of softkey functions specific to History mode. Use the softkey ROLL-DOWN to see additional messages (move from screen 1 to screen 2) and ROLL-UP to backtrack to previous messages (move from screen 2 to screen 1). The softkey HEX switches the display to hexadecimal format, and EXIT leaves History mode.
