ABSTRACT:
A method for the control of voice channel attenuation for the purpose of balancing the level attenuation tolerances of individual functional units in telephone terminal equipment. A non-erasable memory location is provided and contains control data which is utilized by a microprocessor to set an adjustable attenuation element contained in the voice channel. Furthermore, the input level of the voice channel is increased by half the sum of all level attenuation tolerances of the functional units contained within the voice channel. This insures an output level of the voice channel which will be within prescribed limits.
