control frame claimtoken consider first station turned on station notices no tokens sends claimtoken no competitors so makes a ring of just itself
error detection- check sum the checksum generator are subdivides the data unit into equal segments of n bits usually 16 these segments are added
control frames for lost tokens if station goes down token lost predecessor listens for data frame or token noticing none retransmits token sends
