The Catalyst 8500 MSR family can support integrated multiservice ATM switching and Layer 3 switching/routing in a single platform that also supports advanced Cisco IOS services for QoS and security. With the ATM Router Module (ARM), the 8500 MSR can support the seamless transport of IP/IPX traffic between Layer 3 (Gigabit Ethernet/Fast Ethernet) and ATM (T1/E1, IMA, T3/E3, OC-3c/STM-1, OC-12c/STM-4, and OC-48c/STM-16) interfaces at wire-speed. The Catalyst 8500 MSR family delivers campus backbone and metropolitan area network (MAN)/wide area network (WAN) solutions with scalable performance, lower cost of ownership, and the features needed in New World Networks.Wire-speed performance, scalable control, and rich QoS capabilities of the Catalyst 8500 MSR family allow network managers to smoothly integrate the Catalyst 8500 MSR with the Catalyst 8500 CSR, Catalyst 5500, Catalyst 6500, Cisco 7500/7200, LightStream 1010, IGX 8400, MC 3810, and the 3600/2600 product families. Using a Cisco end-to-end solution, they can create a unique solution that truly meets the end-to-end QoS requirement for differentiated services in the enterprise.
