分布式访问 architecture (DAA) has advanced the evolution of cable networks through the decentralisation of selected headend functions. As the decentralised parts process the most time-sensitive tasks, the remaining centralised headend functions become easier to virtualise. DAA is a rational step for the coax-containing network development strategy that leads to 10 Gbps broadband speeds over existing coaxial cables.
The Distributed Access momentum
DAA技术, including Remote PHY and MACPHY, have unleashed a major transformation from analogue optics to digital Ethernet and IP-based transmission. This digitalisation enables the use of the Converged Interconnect Network (CIN), which accelerates fixed-mobile convergence.
Stages and building blocks of successful distributed access deployments
DAA-based broadband to MDUs
Choosing the Distributed Access -based network architecture represents a robust solution for cable MSOs aiming to ensure uninterrupted access to premium broadband services for their subscribers. The solution fits especially well for multi-dwelling unit customers appreciating high broadband speeds, fast installation, and smooth customer onboarding and services.
Industry interoperability leading the way
A prerequisite for sustainable distributed access deployments is an open and standards-based ecosystem that engages several product suppliers, 芯片供应商, and MSOs across the cable industry. 电话este has been active on the collaboration front, and the interoperability of our distributed access solutions with major CCAP core vendors has already been proven in tests, 试用, 现场部署.
