My guess is that they are doing round-robin load balancing, instead 
of per-flow load balancing.

You may not have access to the link's config, but do you have someone 
that you could ask to change the load-sharing algorithm?  (I expect 
you've thought of this, but figured I'd ask).  If they are doing this 
with the idea that one could get more than an E1's worth of bandwidth 
out of a single flow, it sounds like they are misguided....
