A method comprises processing OAM information, determining a bit pattern based on the OAM information, forming FEC parity sync-headers based on the bit pattern, forming an FEC codeword with the FEC parity sync-headers, and transmitting the FEC codeword. An apparatus comprises a receiver configured to receive an FEC codeword, and a 64b66b decoder coupled to the receiver and configured to extract FEC parity sync-headers from the FEC codeword, determine a bit pattern of the FEC parity sync-headers, and determine OAM information based on the bit pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adding operations, administration, and maintenance (OAM) information in 66-bit code","description":"An apparatus comprises a 64b66b encoder configured to process operations, administration, and maintenance (OAM) information, determine a bit pattern based on the OAM information, form forward error co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9654250","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
