ATIS Standard link 

"Removed spammy link to unpublishable copyrighted content - not to any sort of publication at all, but rather, to an abstract and a chance to pay $185 to see actual link."

Not including a link to that standard - which unfortunately, as with many standards, is not freely available - makes this page much less useful for folks looking to support CALEA.  I think that's a big mistake.  That standard is the only standard currently available for Broadband ISP's.
