Dan, Unfortunately the situation changed with the ACA regime commencing 1 July 1997. All NTU are deemed to be the TNV irrespective. However NTU operating above 2 Mbps are deemed to be SELV . This is expected to change as new standards are issued, as the transition is bedded in and the new entities such as ACIF develop their roles.. The reasons are otherwise too complicated for a brief explanation here.
