you might encounter could be 10,000 frames transmitted (or received) with 500 or 1000 retransmits (or receive errors). Link alarms simply tell you that there is some sort of problem on the trunk in async mode. You will find that the link alarms number will correspond to the retransmit and received frames numbers. Specifically, a link alarm means that it has been 10 seconds since the MultiFRAD has received an acknowl- edgment. Normally, three acknowledgments are received during a 10- second period.

The Remote Downs entry means that the MultiFRAD has sent data 30 times and could not get it through (the link between the two MultiFRADs is broken).

The Status Enquiries Transmitted count shows how many enquiries the MultiFRAD has sent to the network. An enquiry is sent every time the Polling Interval Timer expires (default of 10 seconds).

There are 4-counts of status messages received from the network. Status messages are sent by the network in response to the status enquiries from the MultiFRAD. The sum of the status messages re- ceived count and the full status messages received count should equal the status Enquiry Transmitted count.

The Status Messages Received count indicates the number of Keep- Alive status messages the network has sent.

The Full Status Messages Received count indicates the number of Full Status Messages (messages that include the PVC status - either new or active) received in response to a status enquiry.

The Async Status Messages Received count indicates the number of PVC status messages that were received independently, not as a response to an enquiry from the MultiFRAD.

The Bad Status Messages Received count indicates the number of status messages received that were bad due to a frame-level error (a bad CRC or an aborted frame) or a protocol error (due to the wrong management type, etc.)
