plesiochronous

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.
