Events History Log
One extremely useful function provided by the TTDM is the ability to record a series of
events. The TTDM module keeps track of a list of up to 1,024 events (if 1,024 events
are already stored, the oldest event is discarded as a new event is recorded). Events
in the events history log may be specific to one SIM channel or may refer to the TTDM
itself (such as user interactions). For a full list of event types, please refer to “Appendix 1
- Events Glossary”.
