TRANSMIT ORDERWIRE (E1, F1, E2) BYTE OVERHEAD INPUT PORT
The Transmit Order-wire Byte Overhead Input Port provides a dedicated port for the user to insert his/her own
value for the E1, F1 and E2 bytes within the outbound STS-3/STM-1 data-stream. The user should note that
the TxE1F1E2 input pin is sampled (by the Transmit Order-wire Byte Overhead Input Port) upon the rising
edge of TxTOHClk. All of the remaining signals (e.g., TxE1F1E2Enable, TxE1F1E2Frame) are updated upon
the falling edge of TxTOHClk. The timing wave-form and information for the Transmit Order-wire Byte
Overhead Input Port is presented below.
