- Page 3 Features Description The TC1903 "Quick Talk" is designed specifically to extend a regular analog phone line from a PBX to remote location via optic cable. The voice picked up by a handset's mouth piece (connected to the TC1903) is digitized. Because the TC1903 digitizes the analog signals (PCM), voice quality does not degrade over extended distances.
