[NTISP] Multilink with NT into a Cisco 5200

I have a situation with a customer that is dialing in with NT Workstation 4
using two USR 56k Sportster modems (one internal, one external). When he
downloads files, performance is very brisk at about 95 kbps. When he
uploads, there are long pauses with no activity. This happens regardless of
where the site he is uploading/downloading to/from. On our side, we are
using a Cisco AS5248. Using the debug commands, I see lots of lost
fragments and lost fragment timeouts when he is uploading. Any ideas as to
where the problem resides? My first thought is that perhaps the NT machine
isn't breaking up the packets very efficiently when it is its on the sending
end. Any other ideas?

Thanks in advance,
