ATLAS 550 System Manual Section 6, CFG-001

MANUAL: The ATLAS 550 will never initiate DBU until it is manually initiated.

•RESTORE CRITERIA

MANUAL: The primary link is restored only on manual command. This is the only option when NET/DATA FAIl is selected for the Backup Criteria parameter.

NET SUCCESS: The primary link is restored when the network alarm clears.

•STARTUP DELAY

Length of time (in seconds) that determines how long to wait before implementing the DBU capabilities after being configured.

•BACKUP DELAY

•RESTORE DELAY

Length of time (in seconds) that determines how long the main circuit must be restored before dial back- up will switch off.
