Q. How does the Cisco 3800 Series compare with the Cisco 7200 Series?

A. The Cisco 7200 Series features modular and upgradable CPU and hardware-based forwarding engines for maximum flexibility and

performance scalability. The series continues to evolve, with the recent addition of the 1-Mpps-capable NPE-G1 processor, which includes three

onboard Gigabit Ethernet interfaces and several new software and hardware enhancements. The series offers numerous connectivity options, many

of which are not supported on the Cisco 3700 and 3800 series, including Channelized T3/E3, packet over SONET (POS), DPT OC-12, SS7,

ESCON, T3/E3 and OC-3 Circuit Emulation, and FDDI. Like the Cisco 3700 Series, the Cisco 3800 Series targets midsize and large enterprise

branch offices that require a high degree of service and application performance. Cisco 7200 Series routers are aggregation devices, positioned at

sites with integrated applications that require a high density of midspeed connectivity or multiple high-speed connectivity, such as regional

aggregation sites and corporate headend sites.

Table 5 provides a comparison of network modules and port adapters.
