Determining The Station Count - Cabletron Systems MCC-16 User Manual

To connect a fiber optic link segment to the CM:
Remove the protective plastic covers from the fiber ST ports on the
1.
CM and from the ends of the fiber strand connectors.
Attach a fiber strand to the CM's Receive port (labeled Rx) and attach
2.
the other fiber strand to the CM's Transmit port (labeled Tx), as shown
in Figure 2-9.

2.9 DETERMINING THE STATION COUNT

The number of stations supported on a ring depends on the equipment that
constitutes the ring. If the ring contains only devices that implement
Active Re-timing with Jitter Reduction Circuitry (see
example, Cabletron Systems MCC-D2PM and TDRMIM-AT, then the
ring will support 250 stations for all media types. Rings containing any
device(s) that do not implement this circuitry may have lower station
count limits depending on the media type and speed of the ring. The
device that supports the lowest station count will limit the ring to exactly
the same number of stations. Consult the documentation for your
equipment for exact information.
