Overview
ERX routers are modular, carrier-class networking devices that deliver performance,
reliabilit
y, and service differentiation to both b u sine ss 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-optim ized carriers.
