Take full advantage of the high-speed RS-530 port on your bridge or router. In RS-530, the DTE serializes data bits, and the DCE doesn''t restrict the bit sequence. Communication is binary, serial, and synchronous or asynchronous. Control information travels on separate circuits. You can send data at half- or full-duplex, and point-to-point or multipoint, over 2- or 4-wire cable.
