State Description
Isolated Both PHY-A and PHY-B are disconnected from the
ring. There are no connections at either the A or B
FDDI port.
Wrap-A PHY-A is wrapped via the MAC (from PHY-A/Primary
In to MAC to Secondary Out/PHY-A) and PHY-B is
disconnected.
Wrap-B PHY-B is wrapped via the MAC (from PHY-B/
Secondary In to MAC to Primary Out/PHY-B) and
PHY-A is disconnected.
Wrap-AB PHY-B is connected to the MAC (from PHY-B/
Secondary In to MAC to Primary Out/PHY-B) and
PHY-A is wrapped (connecting Primary In to
Secondary Out), isolating PHY-A from the MAC.
