Hi George, it's always a pleasure hearing from you. While I agree with the points you make in the upstream message from this one (no. 1243), I'm slightly perplexed. Was your message rebuttal or additive to what I stated? Intended for someone else? While QWST may be adhering to the traditional add-drop multiplexer (ADM) paradigm (which they most certainly are at this point, at the highest currently achievable, on a commercial basis, SONET rates), newer methods for this capability, some of which are effectively placebos, in my opinion, are now being unleashed through optical means (OADM) in various disguises. These range from sameo sameo digital cross connects (which are still a necessary staple in the broader scheme of things) with the addition of SONET port interfaces, to those whose attributes could be considered more inherently optical, through and through. Let me stop there before this becomes another one of those semantic discussions on the differences between all optical and hybrid o-e. I'd be interested in your views about the recently discussed wavelength routing protocol (WaRP) as featured in Lightwave Magazine recently. I was in the February issue, along with a rather lengthy discussion, I think it was written by Bell Labs folks from LU, on the All Optical Central Office. WaRP would relate to your referenced passive wavelength routing model. Although, probably not at the low-order discrete stream levels needed to satisfy individual end users' requirements. [We get there a little bit at a time, though, don't we?] While we're on the topic of new optical techs, you may have noticed that there is very little activity recently over on the Silkroad thread. Have you heard anything on that score recently? Regards, Frank Coluccio
