• Complete section, line, and path overhead layer termination
• 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
