These generators ring satisfactorily through a line resistance of 25,000 ohms.
RINGER. For resistance see table below. These telephones have enclosed line terminals.
Telephones AB 2305 and AB 2320 are provided with a press button for cutting out the ringer coils and short circuiting the induction coils, the button to be pressed down while ringing.
If specially ordered, we supply these two telephones without the press button, but with the connections so arranged that the ringer is cut out when the generator is operated.
