asymmetrical modulation

communications 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.
