Upload and backup phase:
The new system software is transmitted to the PBX in compressed form and
stored in the dedicated Flash memory on the Flash card. The previous system
software remains stored as a backup.
•
Software update phase:
The current system software is replaced by the freshly loaded system software.
•
Restart phase and version transfer:
The PBX is restarted automatically. The boot software starts the new system soft-
ware and runs a version transfer at the same time.
•
Monitoring phase:
During the monitoring phase, the new system software is active, but the old re-
mains in the Flash memory. In this phase, the old system software can be reacti-
vated at any time with a
"Rollback"
. When the monitoring phase is finished, the
old application is deleted.
