The CommScope RD2322 Remote PHY/MACPHY Device (RxD) is a key component in Distributed Access Architecture (DAA), enabling more efficient broadband delivery by decentralizing network functions. By moving both the PHY and MAC layers to fiber optic nodes, it reduces reliance on headend infrastructure, improving network performance, scalability, and cost efficiency. The RD2322 supports DOCSIS 3.1, IPv4/IPv6, and aligns with future-ready architectures like Flexible MAC Architecture (FMA).

Benefits of the Remote MACPHY solution include:
- Simplicity – All-in-one box – no CMTS Core necessary, "mini CMTS"
- Deployment Flexibility – May be deployed without requiring deployment of a Grand Master Clock
- Low Latency – Benefits from the advantages of deploying Edge Computing
- Compatibility – Compatible with already deployed Video & OOB Aux Cores
- Virtualization – Makes use of Cloud Computing for Management Plane & Video
- Fog Computing – Blends the benefits of Cloud + Edge
- Power Savings – Lowest power solution in the headend

Applications

The RD2322 is ideal for DOCSIS 3.1 upgrades, fiber deep deployments, and hub consolidation projects. It improves signal quality, extends fiber reach, and supports mixed video and DOCSIS environments. With flexible upstream/downstream configurations and support for long-distance DWDM optics, the RD2322 simplifies plant upgrades and expands broadband capacity in small or remote hubs without expanding headend facilities.
