The two primary questions to answer this are "What technology is readily
available?", and "What is the anticipated need?". 

It would be nice if MFS gave historical data at
http://www.mfst.com/MAE/west.stats.html in a format like MRTG does, rather
than just listing weekly traffic ad naseum. 

Already a factor of 10 capacity is available from DEC in their new Gigabit
ethernet Gigaswitches.  The new 12 slot chasis supposedly will run around
$9500, and a two port Gigibit ethernet adapter will supposedly retail for
around $4500 (there also is a multiport 100 base T card).  This is much
cheaper than the FDDI Gigaswitch pricing per port.

Further, yet another factor of 10 is supposedly around the corner from the
company Packet Engines, which has a 10 Gbps ethernet(!) card in
development for their gigabit ethernet switch.

Both of these developments, coupled with the fact that long distance
pricing appears to not be dropping much (and therefore limiting the amount
of bandwith brought to an exchange), should make the exchanges much more
likely to be able to handle to load.
