Downstream Cable Access Module 2 (DCAM-2)
Service Providers deploying the DCAM-2 in an I-CCAP architecture can realize a significant increase in total service groups per E6000 chassis. In addition, the DCAM-2 supports wide deployment of DOCSIS® 3.1 while maintaining all existing DOCSIS 3.0 SC-QAM channels and services. Use of the DCAM-2 requires the RSM-2 and can be implemented via field migration. Beyond I-CCAP, the DCAM-2 can be used to provide downstream Media Access Control (MAC) processing to enable Remote PHY operation on the E6000 CER with a software-only upgrade along with the application of license keys.
Upstream Cable Access Module 2 (UCAM-2)
The Upstream Cable Access Module 2 (UCAM-2) provides hardware support for both DOCSIS® 3.0 SC-QAMs and DOCSIS 3.1 OFDMA operation. Service Providers can deploy both SC-QAMs and OFDMA on each physical port (i.e. each upstream service group) with the UCAM-2. This enables higher throughput, with greater spectral efficiency, while providing backward compatibility for all currently-deployed modems. The UCAM-2 can be deployed with either the Gen 1 or Gen 2 RSM. The UCAM-2 is the only hardware change required to get to DOCSIS 3.1 support in the upstream to supplement downstream support already provided by the Gen 1 DCAM. Beyond I-CCAP, the UCAM-2 can be used to provide upstream MAC processing to enable Remote PHY operation on the E6000 CER with a software-only upgrade and when paired with the DCAM-2,RSM-2 and E6000n RPD.
Router System Module 2 (RSM-2)
The Router System Module 2 (RSM-2) is the heart of a E6000 Gen 2 system. It enables mass deployment of DOCSIS® 3.1 in I-CCAP and Remote PHY architectures, as well as 10G EPON deployments, by providing two critical enhancements. RSM-2 increases the internal link switching speed within the chassis for each client card slot. This enables the E6000 system to switch greater throughput levels from ingress to egress while maintaining low latency. The RSM-2 / RPIC-2Q combination provides a significant increase of Network Side Interface (NSI) uplink capacity, greatly increasing the uplink bandwidth for I-CCAP, Remote PHY, and 10G EPON applications. When operating with two RSM-2s in the same chassis, the active/active nature of forwarding (active/standby control plane) in the E6000 architecture enables double the uplink capacity. The RSM-2 can be used to enable Remote PHY operation on the E6000 CER and enables 10G EPON OLT functionality when paired with the EPFM.
