line driver

A device that extends the transmission distance between terminals and computers connected via private lines or networks. Also called a "short-haul modem" or "limited-distance modem," line drivers can extend a signal that is normally limited to a few dozen or a few hundred feet up to several miles. Line drivers are used to connect point-of-sale (POS) terminals, sensors, machine tools and myriad other digital devices to a host computer.
