Cisco 76-ES+XT-2TG3C= 10 Gigabit network switch module

7600 Series ES Plus XT, LAN/WAN PHY, OTN/G.709, 2x10GE, XFP, DFC3C 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 ES Plus line cards also include synchronization circuitry enabling them to provide standards-based functions for delivering and deriving transport-class network timing, enabling support of network-synchronized services and applications such as mobile backhaul and time-division multiplexing (TDM) migration.
