copied bits in the newly transmitted frame after copying the bits on the
last frame received.

transition or signal error on the Token Ring physical medium

frame containing an improper ring-clock frequency.

Internal Error

erable internal error.

Line Error

detects an error in a received data frame or token that the Ring Station
