AS/CA S043.2:2016， published on 9 August 2016. The objective of this revision is to update AS/CA S043.2 to add requirements for some CE to support Electrical Length Estimation. The principal differences between this draft edition of AS/CA S043.2 and the previous edition are the addition of a requirement for VDSL2 modems to support:
1.Upstream Power Backoff in Equipment Class 10v， consistent with the existing requirement for Equipment Classes 10h and 10j to 10n; and
2.Upstream Power Backoff Length Estimation Method (based on ITU-T Rec. G.993.2 [10]) in Equipment Classes 10h， 10j to 10n， and 10v.
Compliance with these added requirements should be by attestation by the supplier of the equipment.
