MESSAGE DATABASE
All messages received and sent by ELSA AMSC are stored on the hard-disk as a cyclic storage for a duration of 2 days. The following information is also saved a long with the
messages:
- Originator
- Date & time of transmission/receipt
- Date & time of origin
- Priority
- Channel Id.
- Sequence number
- Message Destination
To retrieve mssage we can use one of the following criteria:
- Channel Id+seq. number (transmission)
- Channel Id + seq. number (reception)
- Date & Time (Reception)
- Date & Time (Transmission)
