The Receive Line DCC output port provides a dedicated port for the user to extract out the Line DCC (e.g., D4
through D12) 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 Line DCC output port is presented below.
