Re: I have two telephone lines (numbers) at home, but only one Master Socket. Is this correct?

That one is correct.


On the right side, disconnecting the capacitor converts it from a master socket to an extension. It can be done if they did not have dual extension socket handy.



The capacitor in a master socket is used in conjunction with a resistor, to present the correct test conditions when no phone is plugged in.

Having two capacitor/resistor connections give the wrong reading.
