Editing VDSL (section)

==Profiles==
The VDSL1 standard has three bandplans: Annex A (Asymmetric BandPlan), Annex B (Symmetric BandPlan) and Annex C (Fx BandPlan). Annex A and Annex B were formerly called Plan 998 and Plan 997 respectively.
VDSL1 Annex C is intended for use in Sweden only and it uses a variable separating frequency between the second downstream band, and the second upstream band. All VDSL1 bandplans have spectrum up to 12&nbsp;MHz, so the length of the copper loops must be shorter than ADSL.<ref>{{cite web| url=https://www.itu.int/ITU-T/worksem/asna/presentations/Session_6/asna_0604_s6_p4_palm.pdf | publisher=International Telecommunication Union (ITU) | title=IT-T xDSLxDSL Standards | access-date=2024-01-08}}</ref><ref>{{cite web| url=https://www.itu.int/rec/dologin_pub.asp?lang=s&id=T-REC-G.993.1-200406-I!!PDF-E&type=items| publisher=International Telecommunication Union (ITU) | title=Very high speed digital subscriber line transceivers | access-date=2024-01-08}}</ref>

The VDSL2 standard defines a wide range of profiles that can be used in different VDSL deployment architectures; in the central office, in the cabinet or in the building for example.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-G.993.2/en|title = G.993.2 : Very high speed digital subscriber line transceivers 2 (VDSL2)}}</ref>
