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.

Five models of ERX routers are available:

Juniper Networks ERX1440 Broadband Services Router

Juniper Networks ERX1410 Broadband Services Router

Juniper Networks ERX710 Broadband Services Router

Juniper Networks ERX705 Broadband Services Router

Juniper Networks ERX310 Broadband Services Router

All models use the same software. However, the specific model determines the:

Combination of line modules supported

Conditions for line rate performance of line modules

Type, capacity, and number of SRP modules used
