Does anyone know the requirements for signal transformers for ISDN S/T interfaces in Australia. I do not have a copy of AS/NZS 3260 at this time.
Specifically, I need to know the creepage, clearance, and insulation category requirements for the S/T interface and S/T interface circuits in general. Make the asumption that the power supply of the terminal adapter, meets all the applicable spacing and insulation requirements. Also the teminal adapter is a separate device from the NT1 which is exposed to the outside plant. I've been told the S/T interface could be SELV and only require operational insulation. I believe it should have at least basic insulation. But I've also been told it requires supplementary insulation or reinforced insualation. Any information would be very much appreciated and helpful.
