I'll check it out.  Thanks.  I assume that's TR-TSY-069, a Telcordia 
standard?

Yeah, but the incremental cost of 3-pr drop fiber is likely only to be 
maybe 10-15% of the build, and reducing the flexibility is gonna need a 
big trade-off for me to buy it; remember, my goal is to allow any prem to 
go Layer 1 to wherem ever they want to; they may want both.

(L1 to my other locations, in a ring, and L2 up to a provider from my
hub)
