The Cisco 7600 Series delivers optical WAN and metropolitan-area network (MAN) functionality with high-touch IP services at the network edge. By allowing customers to service-enable their networks at optical speeds, the Cisco 7600 Series helps service providers differentiate their service offerings for a competitive advantage and brings high-speed connectivity to enterprise companies.

Available in three models- Cisco 7603, 7606, and 7609- the Cisco 7600 Series is the most scalable system in the industry for WAN edge aggregation, Internet data center applications, metro aggregation in SONET, Ethernet switched or IP environments, and enterprise networking applications. The Cisco 7600 Series delivers Gigabit Ethernet, Dynamic Packet Transport (DPT), and SONET DS0 to OC-48/STM-16 WAN capability, in addition to 10-Mbps Ethernet to 10-Gigabit Ethernet LAN connectivity.

The Cisco 7600 Series provides an evolutionary upgrade path to IP+Optical networks for service providers that currently provision edge aggregation and services with the award-winning Cisco 7500 Series Router. The Cisco 7600 Series also supports Cisco 7200 and 7500 series WAN port adapters, which provides enterprises and service providers seamless integration with, and migration from existing DS0 to OC-3/STM-1 WAN deployments using the Cisco 7200 and 7500 series.

Key Features and Benefits

Feature	Benefit
Scalable and modular bandwidth capacity	Backplane is scalable from 32 Gbps up to 256 Gbps on the nine-slot chassis and 160 Gbps on the six-slot chassis; crossbar switch fabric (WS-X6500-SFM2) provides scalable bandwidth growth and fail-over protection
Chassis options	Three chassis options (Cisco 7603, 7606, and 7609) specifically designed to fit different space requirements and applications
WAN interfaces ranging from DS0 to OC-48/STM-16	Broad range of WAN interfaces allows scalability as bandwidth requirements grow
High-speed channelized optical connectivity (channelized OC-12 and channelized OC-48 to DS3)	Provides the industry?s highest-density DS3, OC-3, and OC-12 connectivity to enable cost savings and easy deployment
LAN connectivity	Supports the full Catalyst® 6000 Series of high-density/high-speed Ethernet, Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet LAN modules
FlexWAN module for evolution from the Cisco 7500 to the Cisco 7600	Provides both a distinct growth path and investment protection for Cisco 7200 and 7500 WAN interfaces
Parallel Express Forwarding (PXF)-enabled high-performance IP services	Field-upgradable application-specific integrated circuit (ASIC) provides the flexibility and time-to-market advantages of software upgrades with the processing speed of hardware-accelerated IP services
Wide range of IP services	IP services can be applied to rate-limit, shape, and provide traffic queue prioritization, allowing for flexible service definitions per connection.
