OK, that spec makes sense now! Basically, they are using different phrases to mean 'output impedance' and 'minimum load impedance', if I follow you correctly.I have read a bit of history on the early telephone systems, and always marvel how those engineers figured out the balanced line, transmission line principles. impedance matching, etc., way back then. I guess necessity is a mother!
