Removing a Station from the Ring
The Remove Station option on the Station Port menu allows you to remove a
station from the ring so that it can perform a loopback test. When you select this
option, the TRMMIM sends a Remove MAC Frame to the selected station. Upon
receiving this frame, the station will perform a loopback test to verify that its
MAC adapter is functioning correctly.

actions will depend on the manufacturer of the adapter card. Cabletron Token
