Cisco Ethernet Services Plus Transport Extended Product Details
The Cisco 7600 Series Ethernet Services Plus Extended Combination (ES Plus XC) Line Cards are designed for interface-flexible Ethernet services. They allow service prioritization for voice, video, data, and wireless mobility services and can connect to LAN, WAN, and Optical Transport Network Physical Layer (OTN PHY) interfaces as well as Gigabit Ethernet ports on the same physical line card. This unique form factor allows for configurations with redundant network-to-network 10 Gigabit Ethernet interfaces to reside on separate line card slots for resiliency, while offering user-to-network Gigabit Ethernet interfaces on the same slots for efficiency. Service providers and enterprises benefit from the efficiency gains in power consumption, optimized service scale, and feature capability as well as the flexibility in interface speeds for Ethernet solutions.The ES Plus XC cards use the ES Plus card family architecture that relies on programmable interface processors, protecting network investments and reducing total cost of ownership. The extensible design maximizes connectivity options and offers superior service intelligence through programmable interface processors operating at line rate.Designed for delivering flexible Ethernet services in IP/MPLS provider edge networks, and WAN/MAN and OTN applications, the Cisco 7600 Series ES Plus XC Line Cards support port densities of 40 Gbps. The cards feature hierarchical quality of service (QoS), locally significant VLANs. The cards provide the unique ability to combine both Layer 2 and Layer 3 services on the same line card with 10 Gigabit and Gigabit Ethernet ports on the same line card slot. The combination of native Ethernet Layer 2 switching, bridging, Virtual Private LAN Services (VPLS), Ethernet over MPLS (EoMPLS), and Layer 3 IP/MPLS routing distinguishes this line card among other products on the market, particularly in Carrier Ethernet applications.Additionally, the ES Plus XC line cards have the integrated transport capabilities currently found in the ES Plus XT line cards, with WAN PHY and G. 709 Generic Forward Error Correction support on the 10 Gigabit Ethernet interfaces. The ability to span even greater distances between Cisco 7600 series routers is supported with Enhanced Forward Error Correction (EFEC) in the Cisco 7600 series. Operations, administration, and maintenance (OA&M) capabilities are supported in both OTN and WAN PHY interface controller modes, providing insight into link quality and data transmission health.The innovative architecture of these industry-leading, premium Ethernet services line cards is designed to deliver cost-effective, high-touch features, combining both ASIC and network processor technology for an optimal combination of performance and flexibility. The Cisco 7600 Series ES Plus XC Line Cards provide distributed forwarding with proven ASIC technology in the forwarding path, and queuing and shaping functions to optimize the performance of these foundational features. Additionally, four programmable network processors are included in the forwarding plane to facilitate flexibility and feature growth. This ideal technology combination provides customers with the necessary flexibility for future service deployments and allows them to scale the system capacity as required.
