Method for prevention of unnecessary timing corrections

摘要

In plesiochronous multiplex systems with positive-negative or positive-zero-negative timing alignment, according to the invention, after a positive or negative timing correction, no timing correction with opposite signs is permitted unless the phase deviation of the digital signal to be transmitted from the multiplex system clock exceeds a specified amount. Timing corrections with the same sign can be performed without restriction during this guard period, where the guard period in each case starts anew.
