Q. What kind of performance is to be expected from the Cisco 7600 Series?
A. The Cisco 7600 Series is based on high-performance application-specific integrated circuits (ASICs) along with
adaptive network processors capable of forwarding traffic at up to 30 million packets per second (Mpps).
Q. What interfaces are available on the Cisco 7600 Series?
A. The Cisco 7600 Series offers one of the largest selections of WAN, MAN, and LAN interface options in the
industry. These interfaces are made up of the FlexWAN module with port adapters, OSMs, and Ethernet modules.
The interfaces range from DS-0 to OC-48/STM-16 WAN and 10-Mbps to 10-Gbps Ethernet.
FlexWAN Module
The FlexWAN module provides support for Cisco 7200 and 7500 series port adapters. Leveraging this wide range
of WAN port adapters, the Cisco 7600 Series supports interfaces from copper and Channelized T1/E1 and T3/E3 to
T1/E1, T3/E3, and OC-3/STM-1 ATM to OC-3/STM-1 POS and Channelized STM-1.
Optical Services Modules
Adding to the already wide range of interfaces are OSMs. OSMs are line cards that provide support for the following
interfaces: OC-3/STM-1 POS, OC-12/STM-4 POS, OC-48/STM-16 POS, OC-48/STM-16 Dynamic Packet
Transport (DPT), OC-12/STM-4 ATM, Channelized OC-12/STM-4 to DS3, Channelized OC-12/STM-4 to DS0, and
Channelized T3.
Ethernet Modules
High-performance Ethernet capabilities are provided by leveraging the large breadth of Ethernet interfaces from the
®
Cisco Catalyst
6500 Series Switch. The Cisco 7600 Series supports 10-MB, 100-MB, 1-GB, and 10-GB
Ethernet modules.
Q. What are Cisco 7600 Series OSMs?
A. Cisco 7600 Series OSMs are line cards for the Cisco 7600 Series that provide WAN interfaces, PXF IP services
processors for high-speed IP service applications, and deep packet buffers. Each POS and ATM OSM provides an
additional four ports of Gigabit Interface Converter (GBIC)-based switched Gigabit Ethernet as a complement to the
high-speed WAN interfaces on the same line card. Each OSM provides an 8-Gbps full-duplex connection to the
256-Gbps Switch Fabric Module (with dual connectivity to redundant crossbar fabrics), as well as up to 6-Mpps
distributed IP service application to enable high-speed throughput with IP services enabled.
The following OSMs are available now:
• 4-ports Gigabit Ethernet WAN with 2-ports Gigabit Ethernet (GBIC-based)
• 2-port OC-12c/STM-4c ATM (multimode [MM] and single mode-intermediate reach [SM-IR]) with 4-ports
Gigabit Ethernet
• 4-, 8-, and 16-port OC-3c/STM-1c POS (MM, SM-IR, and single mode-long reach [SM-LR]) with 4-ports Gigabit
Ethernet
• 2- and 4-port OC-12c/STM-4c POS (MM, SM-IR, and SM-LR) with 4-ports Gigabit Ethernet
• 1-port OC-48c/STM-16c POS (single mode-short reach [SM-SR], SM-IR, and SM-LR) with 4-ports Gigabit
Ethernet
• 2-port OC-48c/STM-16c POS/DPT (MM, SM-IR, and SM-LR) with 4-ports Gigabit Ethernet
• 1-port Channelized OC-12/STM-4 POS to DS3/E3 (SM-IR) with 4-ports Gigabit Ethernet
