The adaptive clock method does not require information concerning the source clock
transferred over the ATM network. The speed of the transmitter is adjusted to the filling
level of the receive buffer. If the transmit clock is too slow, the buffer filling level will
increase causing the clock recovery circuit to slow down the transmit clock. If the
transmit clock is too fast the buffer filling level will decrease. In this case the clock
recovery circuit will increase the transmit clock.
