Cisco 7600 Series Ethernet Services Plus High Density Line Cards Data Sheet

The Cisco® 7600 Series Ethernet Services Plus High Density (ES Plus HD) line cards are designed for high port density for Ethernet services delivery. The 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 features, which can be transported using G.709 and Forward Error Correction (FEC), allowing optical links to span greater distances.

The ES Plus HD 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. This data sheet contains the specifications for the Cisco 7600 Series ES Plus HD line cards, which are shown in Figure 1.

Product Overview

Designed for IP/MPLS provider edge networks, and WAN, metropolitan-area network (MAN) and optical transport network (OTN) applications, the Cisco 7600 Series ES Plus HD line cards support high 10-Gbps port densities with eight 10-Gbps ports per line card. The cards feature hierarchical quality of service (QoS), locally significant VLANs, and up to 16,000 VLAN IDs per line card for comprehensive 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 these line cards from other products on the market, particularly in Carrier Ethernet applications.

Additionally, the ES Plus HD line cards have integrated transport capabilities with WAN PHY and G.709 Generic FEC (using the 76-ES+OTN/G.709 license) 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 (back-to-back 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 ES Plus HD line cards also include synchronization circuitry, allowing them to provide standards-based functions for delivering and deriving transport-class network timing, providing support for network-synchronized services and applications such as mobile backhaul and time-division multiplexing (TDM) migration.

Recognizing that real-time media dominate next-generation services, Cisco has integrated video monitoring technology into the ES Plus HD line cards. This multimedia technology provides real-time monitoring and statistics collection for video flows, supporting proactive maintenance and management of today's media-rich services, without the use of additional service modules or external probes.

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 an optimal combination of performance and flexibility. The Cisco 7600 Series ES Plus HD line cards provide distributed forwarding with proven ASIC technology in the forwarding path (routing, switching, NetFlow, and access control lists [ACLs]), 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 outstanding technology combination provides customers with the necessary flexibility for future service deployments and allows them to scale the system capacity as required.
