The FS-VDSL Specifications are composed of 5 parts :
The Full Service VDSL Specifications were published on June 5, 2002. This means that anybody can access them from this web site, that any vendor can implement them, provided they comply with IPR rules, and that any operator can use them to provide services on their network.
This forum has therefore achieved the first objective foreseen when the FS-VDSL Committee was set up in 2000. The normal result should have been to wind up the forum on expiry of its work. However, the FS-VDSL specifications are only private documents, with no legal basis and despite their technical value, they cannot be referenced in official procurements in the same way as recognised standards - only official recognised standards have such status.
The Telecommunication Standardisation Sector of the International Telecommunication Union (ITU-T), a multi-governmental entity which is part of the United Nations, has now facilitated this forum to join their efforts to promote global standards. The FS-VDSL Management Committee has agreed to form a specialised group tasked with publishing ITU-T specifications or Recommendations based on the work done so far.
This group has been accepted by the ITU-T management as the FS-VDSL Focus Group. The creation of the Focus Group was formally approved by Study Group 16 at its meeting in October 2002. The parts 2 and 3 of the specifications was reformated by the Focus Group as Recommendation H.610 and part 5 as Recommendation H.611
