Sample Applications for the STS16-20RM and
the STS16-20FRM
The STS16-20RM and the STS16-20FRM switch allow you to make incremental
changes in your network to address both immediate and long-range performance
challenges. For example, a Token Ring LAN of 80 stations including 4 servers
might experience performance problems as a result of increased traffic. As it is
currently structured, the LAN looks like the one in Figure 12.

Figure 12. Typical LAN Segmentation

All of the stations are attached to access units located in a single wiring closet. You
can install an switch in the same wiring closet and divide the LAN into 4 segments
of 20 stations each. One access-unit port from each segment will be connected to a
port on the switch via a patch cable. Finally, the four servers are removed from the
access units to which they have been attached and their cables moved to four ports
on the switch (as depicted in Figure 13).
Each group of 19 users attached to an access unit now shares a dedicated, 16 Mbps
path to the server. Each server has a dedicated, 16 Mbps path upon which to service
requests. The overall capacity of this solution is 64 Mbps; network capacity has
increased fourfold.
