The requirement of a separate payload clock in an ATM system is eliminated by increasing the number of bytes in an ATM cell and controllably generating and inserting idle cells so that a clock rate equal to that of the incoming SDH, SONET or the like clock rate may be used as a read clock. In one embodiment, the number of cells in a predetermined interval, for example 125 mu sec., is adjusted to be a predetermined integer number by inserting idle cells. This, in turn, allows the use of a "standard" available clock to delineate cell boundaries.
