The ACMA proposes to:
Adopt EN50561-1 as an applicable EMC standard for the supply of in-home PLT devices. The ACMA considers that, based on the evidence obtained, the benefits of adopting the standard sufficiently outweigh the potential risks posed by the standard. The adoption of the standard will provide suppliers of in-home PLT devices with a standard that is specific to these devices rather than having to rely on the current generic IT technical standard, CISPR 22.
Provide information for consumers that will identify and explain the potential risks of using in-home PLT devices.
Provide information for industry (including carriers, operators of VDSL2/G.fast systems, retail service providers, PLT equipment suppliers and the cabling industry) that highlights the existence of interference risks. The ACMA will also recommend retail service providers develop operational procedures to assist customers to recognise and remediate interference and performance issues.
Not adopt EN50561-3 at the current time. Despite support from some PLT equipment suppliers to adopt this standard, the ACMA believes that, at this stage, there is insufficient evidence to support the adoption of EN50561-3. Unlike EN50561-1, the standard has yet to be adopted in Europe. The ACMA also understands that PLT equipment suppliers do not have any impending devices that would require compliance with EN50561-3.
Continue to work with carriers and PLT equipment suppliers to assess the interference risk to VDSL2 and G.fast, as well as monitor the development and implementation of the ITU-T recommendation G.9977. ITU-T Recommendation G.9977 is being developed by the International Telecommunication Union Standardisation Sector to mitigate the interference risks between in-home PLT devices and VDSL2 and G.fast systems.
The proposed decision to adopt EN50561-1 into the ACMA EMC arrangements is not intended to establish a precedent for the relaxation of EMC limits for any other technology or product. Any request for the adoption of a prospective new EMC standard will be assessed on a case-by-case basis.
Interested parties are invited to comment on the proposed decision. Comments should be emailed to powerline.telecommunications@acma.gov.au by COB, Friday 24 June 2016.
