The Calix C-Series multiservice over multiprotocol platform is a network transformation vehicle that integrates all functions required to transport and deliver voice, data, and video services over both optical and metallic access networks.

Combining massive capacity with connection density and flexibility, the C-Series supports virtually any service requirement in any network topology.

The flagship of the C-Series—the Calix C7—is not only the most advanced packet-based platform in the industry; the C7 also includes unique multiservice access capabilities, which allow service providers to deploy a single platform to support both advanced services and legacy services.

The multiservice capabilities on the Calix C7 include all standard Ethernet, ATM, and TDM service interfaces. These include legacy services such as 4WTO and DDS circuits. Unlike other "multiservice" platforms, the Calix C7 allows you to provision these legacy services alongside advanced services like Ethernet and GPON—without the operational and capital penalty of adding another device to handle these services.
