FS-VDSL
ITU-T study group
The Full Service-VDSL Committee (FS-VDSL) was founded in July 2000 with the aim of rapidly specifying a low cost, high capability end-to-end multi-service network based on VDSL Frequency Band Plan 998 which can be quickly and economically deployed to enable customers, focusing principally on consumer market, to benefit from competition. It was a non-profit international organization based in Switzerland.
FS-VDSL was closed, according to its statutes, after 3 years of activity. Its specifications, downstreamed to ITU-T Study Group 16 became international standards as Recommendations H.610 and H.611.
At closing time, FS-VDSL was composed of 106 members, including Telcos, Telecommunication manufacturers, chip manufacturers, service providers.
Specifications
The FS-VDSL Specifications are composed of 5 parts :
Operator Requirements Specification (Defining services requirements and infrastructure deployment issues. Protecting digital content is also addressed.)
Architecture (SA) Specification (Defining end-to-end platform architecture and protocols)
Customer Premises Equipment Specification - CPE - (Defining customer equipment configurations and connectivity functions.)
Physical Layer Specification for Interoperable VDSL Systems (Promoting VDSL transceiver interoperability)
Operations, Administration, Maintenance & Provisioning Specification (Defining the operational aspects for economic deployment of VDSL platforms)
FS-VDSL and ITU-T
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.
“FS-VDSL” enters the record as iTU-T study group. Crown Archives preserves that source wording while asking what FS-VDSL, ITU-T and study can confirm, complicate or overturn.
Why this record matters
“FS-VDSL” is worth following because a concise public description often conceals a longer documentary argument. Here, FS-VDSL, ITU-T and study provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2025. The linked authority identifier is Q3063418. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000 and 2002.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
