electrically and acoustically, the 500-series telephones had better efficiency and gain characteristics than their predecessors. the transmission efficiency was 5db higher and the receiver efficiency was 2.5db better on long loops than the 300-series telephones. a significant improvement was the use of equalization circuitry to achieve automatic gain adjustment so that the sets could be deployed with equal performance on short or long local loops from the central office. the g-type handset was newly developed to help realize this efficiency, as the older f series handset was already operating at the peak of its acoustic and electrical design efficiency. the g handset remains the standard handset on many phones, including public payphones.
