Terminal is Turned Off or Power Has Failed
If the terminal is turned off, no calls will be made. While an obvious point, it means that for this
feature to be of any value, the terminal must always remain on.
Communications System Has Failed
A failure of any piece of the communications system will result in missed calls. This includes
the terminal modem, the phone line to the terminal, and any intermediate telecommunications
providers.
Terminal Was Reset or Power Cycled
Since the interval timer is reset when the terminal is reset, a scheduled call may not occur at the
expected time.
To realize the benefits of the Heartbeat Message, the host must be programmed to monitor the
interval between calls from the terminal. It is important to note, though, that the host interval
threshold should be set to a value greater than that programmed at the terminal. A practical
guideline is at least twice the terminal interval. This allows for Heartbeat Message calls that are
delayed because the terminal is in Management mode, or calls skipped because of a system reset.
