                                Backplane Ports


All the concentrators connected to the external dual ring through the front panel
ports on concentrators 1 & 4.

When he disconnect the cable from port B on concentrator #4, all the station
connecting to this concentrator are disconnecting from the ring.

It is look like that when concentrator #4 detects the fail and wrap the ring it
leaves all the M ports out of the ring.
Is it suppose to work this way?
