Carrier Communication Terminals,minals were designed exclusively for telephone conversation. When remote supervision and control entered the picture at some later date, the first carrier terminals built were again of the single-purpose type and their transmission band was chosen so as to fit into the allocation scheme established for the speech frequencies.

In 1947 the German network included, after deduction of all war-incurred losses and prior to reconstruction after the war, some 580 carrier telephone terminals (Fig. 1). In 1960, some 1500 carrier terminals were in operation alone in Western Germany.

Transmission was believed to be a space radiation process with wave propagation concen?trated along the power line route. “Line-bound RF transmission” or similar terms were used at that time to distinguish this mode of operation from wireless RF transmission.
