fractional gigabit ethernet links?

Hello,

I'm trying to troubleshoot a problem with a fractional (311 mbit/second)
gigabit-ethernet line provided to me by a metro access provider.
Specifically, it is riding a gig-e port of a 15454.

The behavior we are seeing is an occasional loss of packets, adding up to
a few percent. When doing a cisco-type ping across the link, we were
seeing a consistent 3 to 4 percent loss.

For fun, the provider brought it up to 622 mbit/second, and loss dropped
considerably, but still hangs at about 1 to 2 percent.

There is no question in my mind the issue is with the line, as we've done
a wide variety of tests to rule out the local equipment (MSFC2s, FYI).

Any clues would be exceptional.
