The Cisco 7609 chassis accommodates a broad selection of line cards supporting numerous applications, including:

-SPAs and SIPs (Cisco 7600 Series SPA Interface Processor-200 [SIP-200], SIP-400, and SIP-600):
– Channelized T1/E1, Channelized T3, and Channelized OC-3/STM-1.
– OC-3/STM-1, OC-12/STM-4, OC-48/STM-16 Packet over SONET/SDH (PoS), and OC-192/STM-64 PoS.
– OC-3/STM-1 ATM, OC-12/STM-4 ATM, and OC-48/STM-16 ATM.
– Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet.

-Enhanced FlexWAN module: Supporting Cisco 7200 and 7500 WAN port adapters from DS-0 to OC-3 for channelized and ATM interfaces and also Fast Ethernet port adapters.

-High-density Ethernet services modules: 10/100 Mbps, Gigabit Ethernet, and 10-Gigabit Ethernet.

-Services modules: IP Security (IPsec), firewall, distributed denial of service, intrusion detection systems, network analysis, and content witching commonly used, for example, in the Cisco Mobile Exchange solution.

-Supervisor support: Cisco Catalyst 6500 Supervisor Engine 32 (WS-SUP32-GE-3B and WS-SUP32-10GE-3B), Cisco Catalyst 6500 Supervisor Engine 720 (WS-SUP720-3B and WS-SUP720-3BXL), and the new Cisco Route Switch Processor 720 (RSP720-3C and RSP720-3CXL)
The Cisco 7609 incorporates many service provider and high-end enterprise carrier-class requirements. Line cards are vertically mounted for efficient cooling with front-to-back airflow. High availability is an inherent facet in the form of redundant power supplies and redundant fan-tray modules. Standard or extended cable-tray inserts provide unrestricted management of either fiber and coaxial or multiple conductor types with up to 48 10/100 cables per slot. Two chassis can be installed per 7-foot rack.
