The Cisco uBR7200 Series MC28U line cards address the expanding service and operational needs of multiple system operators (MSOs). An unmatched set of advanced features and a scalable architecture make these line cards an ideal choice for cable operators facing the challenge of delivering carrier-class IP-based data, voice, and video services to a growing number of subscribers. The line cards offer:Â
• An advanced physical layer (PHY) to provide ingress noise cancellation
• Advanced time-division multiple access (A-TDMA) capabilities
• Advanced spectrum management
• An onboard processor for improved performance to support additional subscribers and services
• Integrated upconverters for Cisco uBR7200 Series MC28U and MC16U line cards
• Flexible software Media Access Control (MAC) domain configuration or virtual interfaces
• Reduced cable wiring through frequency stacking
• Data Over Cable Service Interface Specifications (DOCSIS®), European DOCSIS (Euro-DOCSIS), and J-DOCSIS support on one line card.Â
