ASN Connection Retry Cycle
If an additional alarm condition occurs during one of the Medium Idle Time Between
Re-sends or Long Idle Time Between Re-sends periods, ftServer Manager interrupts
the current cycle. ftServer Manager then attempts to establish an ASN connection
according to the settings of the Short Idle Re-send Count and Short Idle Time Between
Re-sends parameters. If these attempts are not successful, ftServer Manager resumes
making attempts according to the settings of the Medium-Idle or Long-Idle Re-send
Count and Medium-Idle or Long-Idle Time Between Re-sends parameters.
For example, suppose that ftServer Manager failed to establish a call-home connection
and that the next attempt is scheduled to occur three hours from now, due to either a
24-hour or 4-hour wait period. If an additional alarm condition occurs, ftServer Manager
immediately attempts to establish an ASN connection three times with a 10-minute wait
between attempts. If still unsuccessful, the original cycle resumes at the point it was
interrupted with the next dial attempt occurring three hours later.
