15.0 RECEIVE LINE DCC EXTRACTION OUTPUT PORT
15.1
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-12/STM-4 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 waveform and
information for the Receive Line DCC output port is presented below.
