IPSL: 40Mbps Over Copper → Cool but is it spectrally compatible with DSLs

I don't believe this speed reflects a real world deployment since it is not standardized and not spectrally compatible with DSLs. If this technology is not spectrally compatible with T1.417 you can forget about it being deployed by any Telcos and/or co-locators. Maybe for intrabuilding networks but you know what happend to Cisco's LRE....

Yep, bigger question is, will the ILEC even allow a CLEC to install it, presuming the CLEC will want to (Covad is the exception for CLEC who upgrades past ILEC tech). If this is approved by the ILEC, will residential ever see this? or will this be some fractional T3 deliver system, with high install costs since there is no mass production discount?
