Compare also duplex adj., duplex n., triplex adj. (and n.)With the form quadriplex compare quadri- comb. form.

2. Telecommunications. Originally: designating a system of telegraphy enabling four messages to be sent over a wire at the same time, two in each direction (now chiefly historical). Later also: relating to or designating the transmission or reception of four signals simultaneously over one channel or with one aerial.
