GTA-6 Telephone Communications Set - A self contained telephone communications set built by Connecticut Telephone and Electric Corporation. The GTA-6 provided telephone communications for radar stations and their related radar networks. It provided intercommunication between operating personnel at the radar station in addition to communication with outside points in the radar network including direction centers and other radar sites.
The GTA-6 telephone system was a staple of the AC&W radar site because it was the common thread that tied all the mission elements together. In the operations area the GTA-6 allowed the surveillance scope operator to verbally pass tracks to the plotters behind the plotting board and to other radar sites. At most radar scope positions the GTA-6 ten Line Key box gave the operator the ability communicate with ten other positions with the flip of a switch using a headset.
