There is a working group under TIA ( the Telecommunications Industry
Association) TR41.9 committee, chaired by Pierre Adornato
of NORTEL ([email protected]) who is formulating the network harm
requirements for ADSL for inclusion in FCC Part 68 which is the
mandatory standard for the US.  It is anticipated that the work will
be finished in mid 1997, after which a petition for rulemaking will
be submitted to the Commission, most likely from TIA.  In Canada, ADSL
may currently be certified under the Canadian CS-03 mandatory
standard metallic channel requirements.  These requirements are part
of those that did not get "harmonized" with the FCC Part 68.  CS-03 
Standard may be down-loaded from the Industry Canada web site.  
TR41.9 committee's next meeting is scheduled for Dec 10-11 in San 
Diego, CA and ADSL is on the agenda.  You might also want to obtain a copy 
of ANSI T1.413 Standard dealing with ADSL.
