Token Errors 4
A Token Error may indicate that an active monitor either has detected a
recirculating frame or token, or has found that its Timer Valid
Transmission (TVX) time has expired before any token has been detected

monitor is responsible for purging the ring and issuing new tokens in
response to these errors.
