ASN Connection Retry Cycle
2-8 Express5800/320Ma: Technical Reference Guide
can adjust the parameters described in Table 2-3 to increase the time between phone
calls, and thereby reduce the number of attempted calls.
If an attempt to establish an ASN connection fails, ftServer Manager can attempt to
send the alarm over the Internet if the Send Alarms By property is configured for
Internet backup. ftServer Manager also continues to attempt to establish an ASN
connection. All of the parameters in Table 2-3 work together to control how many
attempts ftServer Manager makes to establish the ASN connection. They also control
the length of time between attempts. Table 2-3 shows the default values for these
parameters.
The following example illustrates the ASN connection retry cycle with default parameter
values:
Initial attempt to establish connection fails.
Retry 1: Wait 10 minutes, and then try again. This is the 1st 10-minute wait.
Retry 2: Wait 10 minutes, and then try again. This is the 2nd 10-minute wait.
Retry 3: Wait 10 minutes, and then try again. This is the 3rd and last 10-minute
wait.
Retry 4: Wait 4 hours, and then try again. This is the 1st 4-hour wait.
Retry 5: Wait 4 hours, and then try again. This is the 2nd 4-hour wait.
Retry 6: Wait 4 hours, and then try again. This is the 3rd 4-hour wait.
Retry 7: Wait 4 hours, and then try again. This is the 4th 4-hour wait.
Retry 8: Wait 4 hours, and then try again. This is the 5th 4-hour wait.
Retry 9: Wait 4 hours, and then try again. This is the 6th and last 4-hour wait.
Retry 10: Wait 24 hours, and then try again. This is the 1st 1-day wait.
ftServer Manager continues to make connection attempts every 24 hours.
