RECEIVE ORDERWIRE (E1, F1, E2) BYTES OVERHEAD OUTPUT PORT
The Receive Order-wire Byte Overhead output port provides a dedicated port for the user to extract out the
Order-wire (e.g., the E1, F1 and E2) bytes from that within the incoming STS-3/STM-1 data-stream. The user
should note that all of the output signals (of this port) are updated upon the falling edge of RxTOHClk. The
timing wave-form and information for the Receive Order-wire Byte Overhead output port is presented below.
