The procedure for protecting and recovering a remote modem from failure during a
configuration change is as follows.
1. Prepare in advance a configuration memory that represents a known ‘safe’ or
default configuration for the remote modem. This is the configuration that will be
recalled should a manual reconfiguration of the remote modem result in a loss of
communications with the modem. Ensure that this configuration memory is stored
on the remote modem.
2. Immediately prior to making any manual change to the remote modem, navigate
to its
Edit->Memories->Recall->Advanced
screen and select the radio button
corresponding to the configuration memory to be reloaded in the event of a failure
during the configuration process.
3. Set a reload time. This is the period of time in minutes that the operator has to
make all the necessary configuration changes to the remote modem. It represents
a timeout period after which the modem will automatically reload the selected
configuration memory unless the operator intervenes to cancel the timeout.
4. Click on the
Reload
button to start the timeout period, at which point the screen
will change to that shown in
Figure 6-35
, which shows the remaining timeout
period along with the name of the configuration memory that will be reloaded. In
addition, the
Reload
button changes to a
Cancel
button.
5. Make any necessary changes to the remote modem’s configuration.
6. After completing the configuration changes, navigate back to the
Edit->Memories-
>Recall->Advanced
screen and cancel the timeout by clicking on the
Cancel
button. The screen will now revert to its original format shown in
Figure 6-34
.
