The Pyramid type switchboards are designed to reduce maintenance costs to a minimum, and are recommended up to a maximum of 15 lines. They are compact, highly efficient and reliable.

The jack field is covered with fibre, and the woodwork is finished in our standard matte polish.

The connections are made by means of cordless plugs, and all stations can be interconnected, thus giving the maximum number of simultaneous connections ; also any number of stations can be connected together for a conference.

Normally the plugs must be inserted in the bottom row of jacks, as the lines are, thereby, connected to the indicators. The jacks, in the next row, connect the micro-telephone and generator to the lines for answering and calling purposes. Those in the remaining rows connect the stations, indicated above the jacks, together.

Micro-telephone, generator, night bell and switch, also a spare plug, are provided.
