Hi Frank, The any.DSL hype is a blatant misuse of the term to me. They do 2B1Q SDSL , not ADSL DMT, 2B1Q IDSL, or other xDSL line code iterations at this point--at least judging from the web site. The AN30 appears to have RJ11 voice ports (DSP codecs that must packetize the voice from individual telephones) or T1/E1 port. So the T1/E1 port must be what a PBX with a T1 interface connects into. Then that T1 stream must somehow be SAR'd into ATM cells and probably transported back to the dslam using T1 circuit emulation over ATM over SDSL. They mention GR303 and SS7 in their dslam. What would that do for packetized voice? Also, where would the voice ATM cells be broken back down for final delivery back into voice? Would that be accomplished through an IP/ATM gateway of some sort? If this solution works the way they advertise, wouldn't that eliminate the need for a CLEC to buy an expensive voice switch at each CO to provision voice service? This would enable the CLEC to backhaul the traffic over an ATM pipe to some sort of megapop where the voice switch is finally located. I'm thinking the gateway has to be located at this megapop so the voice can be broken out of the ATM VCs and delivered into the voice switch as T1. Does my thinking make sense, assuming Accelerated Networks claims are valid? Thanks, Hal
