Switchboard Room
A central Switchboard room is where all the important communications emanated. By means of this switchboard, all base lines were made interchangeable. A distribution switchboard was installed in a switchboard room as a standard part of the armaments system.

Plotting Room
Several aiming techniques were developed and used after 1905, but the most precise method made use of two or more widely spaced sighting structures technically known as base end stations. Observers in these structures continuously made bearings of a moving target and the angles of sight were communicated to a central plotting room. In this room the sightings were plotted and future positions were predicted. Corrections were made for meteorological factors, target progress during the projectile flight, and the time taken to calculate and transmit the data. All these variables were computed and translated into aiming directions which were conveyed to the gun crews.
