FDDI station
To implement the FDDI topology, Station Management allows various configurations of FDDI stations.
Basically, a distinction is made between two classes, which result from a connection of the stations to the primary ring or the secondary ring. A further classification allows the FDDI stations to be equipped with media access methods( MAC), resulting in the following breakdown:
- Stations with a connection to both rings and a MAC component: Single MAC Dual Attachment Station(SMDAS).
- Stations with one connection to both rings and two MAC components: Dual MAC Dual Attachment Station( DM DAS).
- Stations with only one connection to the primary ring with MAC component: Single Attachment Station( SAS).
- Concentrator with one connection to both rings (MAC optional): Dual Attachment Concentrator( DAC).
- Concentrator with only one connection to the primary ring (MAC optional): Single Attachment Concentrator( SAC).
