Main Ring

When multiple MAUs are used in a token ring network, the main ring
consists of the cable between the MAUs. The length of the main ring is
critical to proper network operation. The main ring does not include the
cable from MAUs to their LAUs or attaching devices (these cables are
called lobes).
Figure 8. Main Ring
If there is only one MAU for the entire ring, the main ring can be
considered to have no length for installation purposes.
