System Overview
The SmartEdge 1200 router is a carrier-class product with an architecture that supports packetized traffic.
The router can be used as an edge aggregation router and simultaneously as a broadband remote access
server (BRAS) to directly connect customers to the network. It supports a variety of interfaces and vital
services, such as routing protocols, quality of service (QoS), and inbound and outbound access control lists
(ACLs). New services can easily be added with software upgrades.
Because of the optimized packet-forwarding capabilities and support of high-bandwidth uplink interfaces,
the SmartEdge 1200 router can also be used in the metropolitan core to aggregate traffic from other routers
into the long-haul transit core.
