Sample the state of the RxOHFrame signal (e.g., the Rx_Start_of_Frame input signal) on the rising edge of the RxOHClk (e.g., the E3_OH_Clock_In) signal. 2. Keep track of the number of rising clock edges that have occurred in the RxOHClk (e.g., the E3_OH_Clock_In) signal, since the last time the RxOHFrame signal was sampled "High”. By doing this, the Terminal Equipment will be able to keep track of which overhead byte is being output via the RxOH output pin. Based upon this infor- mation, the Terminal Equipment will be able to derive some meaning from these overhead bits. FIGURE 145.
