  • A device which is intended to optimize the use of local data communications facilities, such as those within a building or with a maximum radius of a few kilometers. Such a device, for instance, can condition a digital signal transmitted by an RS232 interface so that it can be reliably transmitted up to several kilometers, instead of the standard 50 to several hundred feet. Also called limited-distance modem, or short-haul modem.
