Abstract: A solid state network for subscriber station is amenable to hybridization and mass production, minimizing costly, heavy components, facilitating transmission and reception of communication signals almost independently of variation in line impedance, and controlling a sidetone level with in-phase signals, through the use of as few as one transmitting transistor that is in series with the transmitter and also in series with the receiver, and as few as one receiving transistor.

Abstract: A solid state subscriber station network which provides transmitting, receiving and regulating functions using a single active element. The transmitted signals, the received signals and the regulatory functions can be separately varied within proscribed limits without adversely affecting the other functions.
