Abstract :
The ECL-¿ space-division-type fully electronic exchange, which uses compound-transistor speech-path elements of an n-p-n-p transistor configuration and parametron control elements and has a 100-line capacity, is described. The exchange is an experimental equipment constructed to study an end-marking system and was completed in September, 1959.
