4.3.1.7 BACKUP MODE 1 SELECT
This screen allows the user to select the mode of backup operation for Backup Channel 1 (Channel 0).
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.
