ABSTRACT:
An amplifier for use with a twisted pair LAN. Each stage of the amplifier provides amplification including higher frequency emphasis for a predetermined length of line. The correct number of stages are automatically activated within the amplifier. Thus a singly configured amplifier may be used for different line lengths.
