E6000-RSM-2 | E6000 CER Router System Module 2 (RSM-2)

The E6000® Converged Edge Router (CER) is a next-generation Converged Cable Access Platform (CCAP™) that provides cable operators unprecedented advances in channel density, power efficiency, and cost savings in a redundant, integrated architecture designed from the ground up for high availability. This powerful design enables operators to converge all services (video, high-speed data, and voice) on a single physical connector, enabling additional savings in capital and operational expenditures along with increased operational efficiency. The Router System Module 2 (RSM 2) is an integral component of the second generation (known as “Gen 2”) set of line cards for the E6000 CER; the Gen 2 modules have been created to deliver additional service group density and greater throughput per service group. Specifically, the RSM 2 enables mass deployment of DOCSIS® 3.1 by providing two critical enhancements. First, RSM 2 increases the internal link switching speed within the chassis to 80 Gbps full-duplex for each client card slot. This enables the E6000 system to switch greater throughput levels from ingress to egress while maintaining low latency. Second, the RSM 2 / RPIC 2Q combination provides a total of 400 Gbps of Network Side Interface (NSI) uplink capacity, greatly increasing the uplink bandwidth for both Integrated CCAP as well as Remote PHY applications. When operating with two RSM 2s in the same chassis, the active/active nature of forwarding (active/standby control plane) in the E6000 CER architecture enables as much as 800 Gbps of uplink capacity. The RSM 2 can be used to enable Remote PHY (R PHY) operation on the E6000 CER with a future software upgrade.

The RSM-2 increases the internal link switching speed within the E6000 system by providing 80 Gbps full-duplex to each client card slot. In addition, the RSM-2 / RPIC-2Q pair has a total of 400 Gbps of Ethernet NSI capacity, which doubles to 800 Gbps when deploying with two RSM-2s in a chassis. Deployment of the RSM-2 enables use of the DCAM-2. With these capabilities, the RSM-2 supports more service groups per chassis with more throughput in each service group. Operators receive significant benefits in terms of operational simplicity, cost savings, and competitive advantages by deploying the RSM-2. The RSM-2 is not compatible with the Gen 1
DCAM or the Gen 1 UCAM.
