Disadvantages of the Monocord Switchboard.

1. It does not afford as quick connections as the by-cords switchboard type.

2. It is not self-contained. A self-contained switchboard includes operators, receiver and transmitter and ringing and night alarm circuits.

3. The operator’s telephone is usually equipped with a hand set, (receiver and transmitter) which leaves him with only one free hand for making connections.

4. One switchboard is equipped with but one master, or operators cord, this affords only one means of answering and calling.
