The Communications Alliance has updated two vector-related industry standards which it claims will help equipment suppliers and retail service providers ensure broadband modems on copper lines can support high data rates and reduce interference.
The standards were developed by 17 organisations, including NBN Co, telecommunications providers, carriage service providers, equipment suppliers, and regulators.
The first adds technical requirements for vectored VDSL2 into modems, while the second extends DSL filters to cover the VDSL2 frequency band.
Comms Alliance chief executive (CEO), John Stanton, said the drafts are the “essential underlying technical framework for end user premises, needed to ensure that vectored VDSL2 can deliver its promised benefits as part of the new NBN technology mix.”
Stanton claims that VSDL2 “has been shown in Australia and elsewhere to be a valuable technology that can deliver near-fibre data rates using, in part, the copper ‘last mile’,” and that without appropriate parameters, the speed increase from vectoring will be largely lost.
“This last point is particularly important as the NBN rolls out across the country,” he said. “In each area migrating to the NBN there will be an 18 month period during which new and legacy services need to co-exist without undue interference to one another, until eventually all fixed terrestrial services end up being migrated to the NBN.”
The Comms Alliance has opened the drafts for public comment until November 25.
