- (communication) Almost, but not quite, synchronous.
- The DS-3 standard uses bit stuffing to allow the clocks of its tributaries to be plesiochronous.
From Ancient Greek Ï€Î»Î·ÏƒÎ¯Î¿Î½ (plÄ“sion, “near") + Ï‡ÏÏŒÎ½Î¿Ï‚ (khronos, “time").
plesiochronous - Computer Definition
From the Greek plesio, meaning near, and chronos, meaning time, plesiochronous communications involves devices running at nominally the same rate. Plesiochronous networks comprise subnetworks and devices that are free-running, although at approximately the same rate and within defined parameters of tolerance for variation. Much as clocks and watches run at approximately the same rate, devices in a digital network are free-running, with some running at a slightly faster or slower pace.
A transmission where the sending and receiving devices are synchronized but set to different clocks. Although the bits may not arrive in the same time slot as they were sent, as long as they arrive within a certain, defined range, the transmission is said to be plesiochronous (almost synchronous).
