Bob, While I fully understand and concur with you concerning ring *voltage*, that is not my point of concern in relation with the LVD. Ring voltages are not passed through end-to-end on T1 or E1. I have and do work on plenty of equipment that only DCS's or IMUX's T1 or E1 and powered by 48vdc. Ring voltages don't exist on T1 or E1.
Maybe this is one of those areas that not many people are aware. Ring voltages are not passed on the T1/E1 line. It is not in either spec. There are plenty of equipment out there that handle only T1/E1 levels and 48vdc. They have nothing to do with ring voltages. So trying to apply the letter of LVD 73/23/EEC won't work. It's still done though, but it's a major hole in the LVD that I'm becoming more convinced few are aware. I was surprised to find it. Glad I wasn't on the committee. ************************************************************ ------------------------------------------------------------ The comments and opinions stated herein are mine alone, and do not reflect those of my employer. ------------------------------------------------------------ ************************************************************
