Or indeed, just providing a full T3 or E3 (in terms of transmission), but
not putting 45M / 34M of traffic through it.  This is easier if you own the
equipment at both ends of the link, of course.

I have some non-Cisco devices which support physical T3/E3 interfaces but
not line-rate traffic (at least a realistic packet sizes, additional
features and CPU load), but we are deploying them with L3 traffic-shaping to
a "supportable" bandwidth on the WAN.

Tim.
