Cable

MSOs can leverage existing M-CMTS architecture to allow them to meet customer demands for higher bandwidth with pre-DOCSIS® 3.0 edgeQAMs and channel bonding features. This architecture separates the downstream physical layer processing from the core CMTS and moves it to Harmonic's NSG 9000 universal edgeQAM, improving downstream data rates and significantly reducing costs. The NSG 9000 supports both wideband M-CMTS and M-CMTS solutions delivered using existing cable modems. The NSGs are already deployed in over 10 M-CMTS systems around the world including North America, Asia and Europe.

Harmonic’s NSG 9000 offers operators a seamless migration path to full DOCSIS 3.0 support. The NSG is integrated with the DOCSIS 3.0 timing interface (DTI) for timing synchronization between the core-CMTS and the edgeQAM. The NSG 9000 complies with the DOCSIS 3.0 RFI specification, and exceeds the specs in several critical RF parameters such as power level, return loss, etc. The NSG 9000 already supports the DEPI D-MPT data plane, integrated and deployed with a leading CMTS platform.
