A virtualized CMTS for a smarter broadband network

Our cOS virtualized Cable Modem Termination System (vCMTS) software deploys on Commercial off-the-Shelf servers (COTS), or as a cloud-native application in your existing data center. Agnostic to the Remote PHY Device (RPD), the high-performance vCMTS software integrates full DOCSIS functionality with a flexible pricing model. In both centralized and Distributed Access Architectures (DAA), you can run multiple deployment models, or a hybrid, and be ready for 10G PON.

Common control, easy scaling, and IP traffic forwarding boost your network efficiency with tens of gigs of capacity per rack unit. Your access network can efficiently power next-generation broadband speeds today.
