	A DS1 is a bi-dir sync path.  You have 1.544Mbit *each* way.

	So, you are at 94.7% of max on the incoming, and 33.1% of max
on the outgoing.

	Given that these are 5 min average values I would say that
your DS1 is more than saturated.  BTW:  This type of usage is normal
for an ISP that primarily serves customers rather than content.
