Cisco 7600 Series - Ethernet Services Plus XT 20 G and 40 G Line Cards for Carrier Ethernet [Cisco 7600 Series Routers]

The Cisco® 7600 Series Ethernet Services Plus Extended Transport (ES Plus XT) Line Cards 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. Service providers and enterprises benefit from the efficiency gains in power consumption, improved economics from higher density, as well as advanced Carrier Ethernet features, which can be transported using G.709 and Forward Error Correction (FEC) across dense wavelength-division multiplexing (DWDM) networks, enabling optical links to span greater distances.

The ES Plus XT cards use an architecture first developed for the Cisco 7600 Series ES Plus card family, with programmable interface processors that protect network investments and reduce total cost of ownership. The extensible design maximizes connectivity options and offers superior service intelligence through programmable interface processors operating at line rate. This data sheet contains the specifications for the Cisco 7600 ES+ Series Line Cards as shown in Figure 1.

Product Overview

Designed for interface flexibility and IP-over-DWDM integration in Carrier Ethernet, IP/Multiprotocol Label Switching (MPLS) provider edge, and WAN/MAN applications, the Cisco 7600 Series ES Plus XT Line Cards support up to 40 Gbps of bandwidth with four ports of 10 Gigabit Ethernet interfaces, or 20 Gbps with two ports of 10 Gigabit Ethernet. The cards feature hierarchical quality of service (QoS), locally significant VLANs, and up to 16,000 VLAN IDs per line card for rich services at scale. The cards provide the unique ability to combine both Layer 2 and Layer 3 services on the same line card. 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 line cards have integrated G.709 Generic Forward Error Correction (available with the purchase of the 76-ES+OTN/G.709 license) to span regional distances with integration directly into OTN devices such as the Cisco ONS 15454 Multiservice Transport Platform (MSTP) or core routers such as the Cisco CRS-1 Carrier Routing System. The ability to span even greater distances between Cisco 7600 Series Routers is supported with Enhanced Forward Error Correction (EFEC) in the ES Plus XT cards (back-to-back ES Plus XT connections). 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 application-specific integrated circuit (ASIC) and network processor technology for optimal performance and flexibility. The Cisco 7600 Series ES Plus XT Line Cards provide distributed forwarding with proven ASIC technology in the forwarding path (routing, switching, NetFlow, access control lists [ACLs]), and queuing and shaping functions to optimize the performance of these foundational features. Additionally, four (for the ES Plus XT 40G line cards) or two (for the ES Plus XT 20G line cards) 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.
