Darrell, I appreciate your comments on this. just a couple of things below:

CL: not my customer, so I can't comment. one of the engineers I work with was telling me about it. I suppose this might be one of those customers who wants to solve every problem with more speed, but I don't know. Plus you have to remember that I work for a telco, and the telco wants to sell transport - i.e. data lines. > > Why send back Sonet to the customer hub site?

Each line comes into the customer prem and is termionated on the JDS Uniphase 1280 GBX. The unit is 1.75" high, but with a couple three hundred of them, you are talking several racks worth, not to mention the equipment to terminate all those gig SX ports, and the connecting fiber patch cables. > > It sounds like the spoke sites are all within very close proximity, using > only a handful of CO's.
