Abstract
The present invention provides a method for evaluating a communication link between a first communication site and a second communication site. The first and second communication sites increment a sent counter and reset a received counter upon sending a message to the other communication site. Each communication site also increments a received counter and reset a sent counter upon receiving a message from the other communication site. When the sent counter exceeds a sent threshold, the communication system site sends an alert that the communication link is down. When the received counter exceeds a predetermined percentage of the other communication site's sent counter, the site sends a message to the other communication site to let the other communication system site know that it is still receiving messages.
