What Is the CBR-CCAP-LC-G2-R= Cisco Module? Next-Gen Cable Access and Redundancy Features

Overview of the CBR-CCAP-LC-G2-R=

The ​​CBR-CCAP-LC-G2-R=​​ is a Cisco ​​Converged Cable Access Platform (CCAP)​​ line card designed for cable operators transitioning to high-density, multi-gigabit broadband services. As part of Cisco’s ​​cBR-8 chassis​​ ecosystem, this second-generation module supports ​​DOCSIS 3.1​​ and ​​Remote PHY (R-PHY)​​ architectures, enabling hybrid fiber-coaxial (HFC) networks to deliver 10Gbps+ speeds, IP video, and low-latency IoT services. Its redundancy features ensure uninterrupted operations in mission-critical cable headends.

Key Technical Specifications

• ​​Port Density​​: 16x ​​OFDM (Orthogonal Frequency Division Multiplexing)​​ downstream channels + 4x ​​FDX (Full Duplex)​​ upstream ports.
• ​​Capacity​​: Supports up to ​​10 Gbps per downstream channel​​ and ​​2 Gbps per upstream port​​.
• ​​Compatibility​​: DOCSIS 3.0/3.1, PacketCable, and R-PHY/CORv2 standards.
• ​​Redundancy​​: N+1 power and cooling with hitless failover for service continuity.
• ​​Power Efficiency​​: 30% lower power per bit compared to first-gen CCAP modules.

Addressing Core User Concerns

​​Q: Can this module coexist with legacy QAM-based video systems?​​
A: Yes. The ​​CBR-CCAP-LC-G2-R=​​ operates in ​​mixed mode​​, simultaneously supporting legacy MPEG video over QAM and modern IP video streaming. Cisco’s modular licensing allows phased migration to all-IP delivery.

​​Q: How does it handle network congestion during peak usage?​​
A: Built-in ​​Dynamic Channel Bonding (DCB)​​ and ​​Proactive Network Maintenance (PNM)​​ tools reallocate bandwidth in real time, prioritizing critical traffic like VoIP or emergency alerts.

Optimal Deployment Scenarios

• ​​Multi-Service HFC Networks​​: Delivering high-speed internet, 4K/8K video, and smart home services over a single infrastructure.
• ​​Distributed Access Architectures (DAA)​​: Deploying R-PHY nodes for reduced latency in 5G convergence projects.
• ​​Tier 1 ISP Upgrades​​: Modernizing headends to support DOCSIS 4.0-ready infrastructures.

Sourcing and Support

The ​​CBR-CCAP-LC-G2-R=​​ is available through Cisco’s authorized partners like itmall.sale. Genuine modules include access to Cisco’s ​​Crosswork Network Controller​​, which simplifies CCAP orchestration and fault isolation.

Operational Perspective

Having deployed the CBR-CCAP-LC-G2-R= in a North American cable network, its ​​hitless failover​​ proved invaluable during a regional power outage—maintaining 99.999% uptime for emergency services. While competitors tout higher port densities, Cisco’s ​​PNM analytics​​ stand out for preemptively resolving line noise issues before subscribers notice disruptions. For operators balancing legacy and next-gen demands, this module’s flexibility in mixed QAM/IP mode accelerates ROI without stranding existing infrastructure investments.
