BACKUP MODE 2 SELECT
This screen allows the user to select the mode of backup operation for Backup Channel 2 (Prime Channel
9), if this channel is configured as a backup channel. The following backup modes are available:
•
Manual - allows the operator to force backups to occur even if prime channel modems have not
failed.
•
Non-Revertive - allows automatic backups to occur when prime channels fail, but once a channel
is backed up, it will remain backed up until manually reset by the operator.
•
Revertive - allows automatic backups to occur when prime channels fail, and after a channel is
backed up, if the prime channel clears its error, the backup can become available for another
prime channel.
