Equipped with strips of 10 drop indicators N4815D, strips of 10 jacks with numbered labels for the lines and enclosed type push-button restored indicators for clearing on the keyboard.

Associated with each pair of cords and the clearing indicator there is a speaking and ringing key, and in addition a common "ring back" key is fitted for ringing on the answering cords.

The night alarm is mounted inside and a key on the keyboard for switching it on or off as desired. A hand generator and a Bakelite micro-telephone are provided for the operator.
