You mean backhauling end-office traffic and picking it all up at the 
access tandem without getting DEOT, despite incurring considerable usage?

If so, I thought that's what the

    usage >= DS1 ? DEOT : tandem

rule was meant to remedy, rather than having to have TGs to every tandem?

I'm thinking specifically of CLECs that got their license and started 
the interconnection process at the tail of BellSouth, and now face 
actually dealing with AT&T for turn-up, expansion, POI & transport 
changes, etc.
