The Cisco 7606 Router is a compact, high-performance router designed in a 6-slot form factor for deployment at the network edge, where robust performance and IP/Multiprotocol Label Switching (MPLS) services are necessary to meet the requirements of both enterprises and service providers. It enables Carrier Ethernet service providers to deploy an advanced network infrastructure that supports a range of IP video and triple-play (voice, video, and data) system applications in both the residential and business services markets. The Cisco 7606 also delivers WAN and metropolitan-area network (MAN) networking solutions at the enterprise edge. With a powerful combination of speed and services in a compact form factor, the Cisco 7606 is an outstanding choice for multiple applications. Whether deployed as a high-speed WAN aggregator, as a device for peering, as a residential broadband services aggregator, or as a device for Metro Ethernet aggregation and uplink, the Cisco 7606 meets requirements for redundancy, high availability, and rack density. In the point-of-presence (POP) enterprise edge or the metropolitan network edge, the Cisco 7606 sets new standards as part of the industry-leading Cisco 7600 Series Routers (Figure 1). With a forwarding rate of up to 240-Mpps distributed and 480-Gbps total throughput, the Cisco 7606 provides performance and reliability with options for redundant route processors and power supplies. The inclusion of two Gigabit Ethernet ports on the Cisco Catalyst ® 6500 Supervisor Engine 720 with the Multilayer Switch Feature Card 3 (MSFC-3) or the new Cisco Route Switch Processor 720 (RSP 720) with the MSFC-4 used in the Cisco 7606 eliminates the need for a line-card slot for uplink ports. The result of this design is more efficient use of available line-card slots and increased deployment flexibility. Four Gigabit Ethernet ports are available for use in dual-route processor configurations. Shared port adaptors (SPAs) on the SPA interface processors (SIPs) are available on the Cisco 7600 Series with interface speeds ranging from OC-3 to OC-192 and from Fast Ethernet to 10 Gigabit Ethernet. The Cisco 7600 Series can also use the Cisco 7600 Series/Catalyst 6500 Series Enhanced FlexWAN Module to take advantage of most Cisco 7200 and 7500 Port Adapters for terminating DS-0 to OC-3 speeds. By using the Cisco Catalyst 6000 Series of Ethernet line cards in conjunction with the SIP-based SPAs and the enhanced FlexWAN module, the Cisco 7600 provides a multitude of options to scale WAN connectivity from DS-0 to OC-192 and LAN connectivity from 10-Mbps Ethernet through 10 Gigabit Ethernet.
