nolram Posted November 20, 2005 Report Posted November 20, 2005 hello everyone! I want to ask somebody out there to shed light on my questions: Why is it that landline telephone accepts -48Vdc? Why is it Quote
nitrojunx Posted November 22, 2005 Report Posted November 22, 2005 this is to avoid cathodic effect, that is -48volts with respect to ground... Quote
