      We have just finished designing a cabling plant that divides that
campus buildings into 16 logical rings, all connected by fiber, and a
backbone that connects all the rings.  Each building will get 18 fibers.
This will allow for a main path (with built in backup path), a full
backup set of fibers (used 4 so far), 2 for another net to run
concurrently (if neccessary), 2 for its backup, and the rest to be used
for any future needs (including telephone, video, security, direct links
between certain dept.'s, etc).  

We are linking 44 buildings, and the total length of fiber is about 5.85
miles.
