John this may have been posted ,, but it worth reading again :-) post.messages.yahoo.com id=32489 Michael Weissman of PairGain Technologies wrote: “The are two reasons for our excitement about HDSL2 at PairGain. First, we basically invented it. Our Chief Scientist Dr. George Zimmerman's contribution to the ANSI standard was that of OPTIS. This stands for Overlapped Pam Transmission with Interlocking Spectra. This is the TC-PAM method submitted by Dr. Zimmerman and ultimately adopted by the T1/E1 committee. Second, I believe we are the first equipment manufacturer to actually ship HDSL2 product. I don't mean field trial units or evaluation units, we are currently shipping production product, in production quantities. Relative to the SDSL/HDSL2 question HDSL2 technology is certain to take over the SDSL market. HDSL2 is a standards based technology that offers vendor interoperability. Service providers have been asking for this for years! Service providers are no longer tied to proprietary solutions. And, HDSL2 is a robust design and spectrally compatible (due to OPTIS) so it will not interfere with other services in the same bundle. SDSL uses 2B1Q , so there are spectral issues. With SDSL, service providers are collared by proprietary solutions. The upcoming g.shdsl standard which addresses multi-rate, will allow all the benefits of HDSL2 with an even greater reach.
