Definitions for "Beaconing"
Token Ring process to recover the network when any attached station has sensed that the ring is inoperable because of a hard error Stations can withdraw from the ring if needed. A station detecting a ring failure upstream transmits (beacons) a special MAC frame used to isolate the location of the error using beacon transmit and beacon repeat modes.
The repeated transmission of a frame sent by an adapter to indicate a serious ring problem, such as a broken line or power failure. The transmission will continue until the error is corrected.
A signal repeatedly displayed on a Token Ring NIC on detection of a problem.
