Shared User Ring
Switching to the workgroup can help alleviate this problem.
The DeskStream can be connected between the CAU and the
Ringswitch using the single Master (or node) port (24) on the
DeskStream to connect to the CAU and one of the Direct (or
concentrator) ports, or an uplink port to connect to the Ringswitch.
Once the DeskStream is connected and operational, the power users
can be moved across simply by moving the cable connection - no
other configuration activity is required. These users now get a
dedicated connection and will also release bandwidth for the
workstations remaining on the shared medium ring.
CAUs and RAMs can’t use full duplex DTR, but the DeskStream can!
So the uplink to the Ringswitch is a more efficient link than the
original CAU link.
