Abstract :
The transmission of telegraph or data signals by carrier frequencies operating in the voice-frequency band involves considerations not normally associated with voice signals transmitted in this band. Transmission requirements for the data or telegraph carrier facility may range from those of a single-channel 2-wire system to the maximum of a 26-channel 4-wire system.
