About the Cisco cBR-8 CBR-8D31-16U31-SP Cisco cBR-8 converged broadband router
The Cisco cBR-8 CBR-8D31-16U31-SP converged broadband router delivers 16 downstream DOCSIS 3.1 OFDM channels and 16 upstream DOCSIS 3.1 OFDMA channels in a modular, rack-mountable chassis designed for cable service provider environments. This platform supports both DOCSIS 3.0 and DOCSIS 3.1 standards, with downstream modulation via OFDM for DOCSIS 3.1 and QAM 64/256 for DOCSIS 3.0, while upstream traffic utilizes OFDMA for DOCSIS 3.1 and QPSK/QAM for DOCSIS 3.0. Running Cisco IOS-XE, the cBR-8 integrates advanced Layer 3 capabilities including IP routing, MPLS, VPN, QoS, and multicast support, with routing protocol options spanning BGP, OSPF, IS-IS, and static routing.
Service provider network engineers and cable headend operators choose the CBR-8D31-16U31-SP for its proven architecture in hub-site and access-edge deployments. The system features supervisor and line card redundancy to ensure carrier-grade availability, while its Remote PHY support provides compatibility with Cisco Remote PHY DAA architecture for flexible network scaling. Management flexibility is delivered through multiple interfaces—NETCONF, YANG, CLI (SSH/Telnet), and SNMP—enabling seamless integration into existing OSS/BSS workflows. The modular, rack-mountable design accommodates expansion as service footprints grow.
