ICations> A scheme to maximise use of a communICations line by giving a larger share of the bandwidth to the modem at the end whICh is transmitting the most information. Only one end of the connection has full bandwidth, the other has only a fraction of the bandwidth. Normally, whICh end gets the full bandwidth is chosen dynamICally. AsymmetrICal modulation was made famous by the HST mode of the early high-speed modems from US RobotICs. (1998-03-13)
