Edgile 4G
Edge Router with Broad Band Remote Access Server

Application

FTTC networks set up and maintained by Local Cable Operators
Small Office/Home Office Ethernet Switch
Networking of Enterprise Network and Campus Network

As shown by the diagram, the traffic from various service providers and their customers carrying various services(voice, video and data) is aggregated by Tier-2 switches (like Xtera 500 and Xtera 1000). The uplinks of Tier-2switches is in turn consolidated by Tier-1 switches and fed to BRAS. In DSL deployments, Tier-1 switches collect traffic from DSLAMs rather than Tier-2 switches. In both cases the Edgile-4G provides the subscriber sensitivity and service sensitivity. Edgile-4G is the point where Quality of Service and Call Admission Control considerations are implemented. The billing information is collected and passed to the RADIUS server. The Video on Demand and Video Multicast sources are also
injected at this point. Edgile-4G also serves as the first MPLS-PE node in the network.
