# Overview

ERX routers are modular, carrier-class networking devices that deliver performance, reliability, and service differentiation to both business and consumer Internet users. The ERX7xx and ERX14xx models offer high port density, low power consumption, and fully redundant Internet access routing and edge aggregation. The Juniper Networks ERX310 Broadband Services Router supports the same services, but with smaller capacity and scaling capabilities. ERX routers offer the complete edge solution for IP-optimized carriers.
