I found a similar issue in a local portion of Sprint's network years back. 
It worked mostly fine, except there were certain bit patterns the 
misconfigured circuit just couldn't pass.  That manifested itself as a 
customer complaining that there was a certain binary file on their (web or 
ftp, can't remember) site that many remote users couldn't download.  It'd 
always get to the same point and the xfer would stall.  Testing it 
locally, it worked fine.  That was fun (and educational) to troubleshoot.
