upstream neighbor could not set the address recognized bits or frame
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 Copy Records when a reporting Ring Station copies a frame containing the

frame containing an improper ring-clock frequency.

erable internal error.
