• Generation and verification of BIP-8 parity

• Pointer processing for receive payload extraction and transmit payload mapping

• Extraction and insertion of transport and path overhead from/to dedicated external pins or from registers

• WIS alarm insertion and detection

• Frame-synchronous X7 + X6 + 1 scrambling and descrambling

• Error rate monitoring

10 GbE Processing
