7.2 Error Signalling
A station detecting an error condition signals this by transmitting an ERROR FLAG. For
an ’error active’ node it is an ACTIVE ERROR FLAG, for an ’error passive’ node it is a
PASSIVE ERROR FLAG. Whenever a BIT ERROR, a STUFF ERROR, a FORM
ERROR or an ACKNOWLEDGMENT ERROR is detected by any station, transmission
of an ERROR FLAG is started at the respective station at the next bit.
Whenever a CRC ERROR is detected, transmission of an ERROR FLAG starts at the
bit following the ACK DELIMITER, unless an ERROR FLAG for another condition has
already been started.
