You are correct Peter. At this point in time that is how it is treated. There is currently a draft proposal for the IEC 950 standards addressing this type of circuit, which will be called an RFT Circuit (Remote Feeding Telecommunications Circuit). The RFT will be divided up into 2 categories: Limited Current (RFT-C), & Limited Voltage/Restricted Access (RFT-V).
Hope this helps...I do not know the current status of HDSL with the FCC. Mel Pedersen Midcom, Inc.

America with an HDSL interface having max 260 Vdc between the lines and 130 V between each line and earth. The maximum current limitation is 75 mA. How is this interface treated? Since it does not meet the requirements for TNV-1, TNV-2, TNV-3, I believe it should be treated as a secondary hazardous circuit but also applying the requirements for Overvoltage and output current limiting requirements. Also, does any one know the status of HDSL with FCC? Peter Merguerian Managing Director Product Testing Division I.T.L. (Product Testing) Ltd.
