Overview

ERX routers are modular, carrier-class networking devices that deliver performance,

reliabilit

y, and service differentiation to both business and consumer Internet

users. The ERX-7xx and ERX–14xx models offer high port density, low power

consumption, and fully redundant Internet access routing and edge a ggregation. The

ERX-310 ro

uter supports the same services, but with smaller capacity and scaling

capabilities. ERX routers offer the complete edge solution for IP-optimized carriers.
