<communications> Nearly synchronised, a term describing a communication system where transmitted signals have the same nominal digital rate but are synchronised on different clocks.

According to ITU-T standards, corresponding signals are plesiochronous if their significant instants occur at nominally the same rate, with any variation in rate being constrained within specified limits.
