The Calix C7 represents the most advanced Ethernet service delivery platform in the marketplace today. Service can be delivered over both copper and fiber using any mix of technology ranging from DSL to GPON and GE interfaces. Access services can be delivered in any VLAN model the service provider desires—VLAN per service, VLAN per subscriber, or a mix of both. Q-in-Q is also supported directly on the Calix C7 without the need to have upstream equipment add additional tags.

In addition to supporting these advanced Ethernet models, the Calix C7 also provides significant Ethernet and IP security for the access network. This is accomplished by locking down the network to prevent users from spoofing IP and MAC addresses. Malicious users are very easy to identify and eliminate by using the advanced management tools supported by the Calix C7 and the Calix Management System (CMS).
