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
