TRANSMIT LINE DCC INSERTION INPUT PORT
The Transmit Section DCC Insertion Input Port provides a dedicated port for the user to insert his/her own
value for the D4 through D12 bytes within the outbound STS-3/STM-1 data-stream. The user should note that
the TxLDCC input pin is sampled (by the Transmit Section DCC Insertion Input Port) upon the rising edge of
TxTOHClk. The TxLDCCEnable output signal is updated upon the falling edge of TxTOHClk. The timing
wave-form and information for the Transmit Line DCC Insertion Input Port is presented below.
