Moderators, please feel free to re-post this somewhere more appropriate, if necessary.

Is there a program and/or a piece of hardware that can be installed at a remote site that will allow me to be notified by an alarm transmission (via a plain old land line-based alarm system) if a remote computer/router/cable modem has lost contact with the internet?

A customer uses a computer at a remote location to send video feeds from security cameras. He needs to be notified immediately if and when that location loses its internet connection. The location has a central station alarm panel, with a land-line connection and back-up cell communicator, available that has extra unused zones.
