B-RAS
Broadband Remote Access Server
The B-RAS is a functional entity of DSL networks which is effectively the first point at which a subscriber’s IP traffic is processed for onward routing. Typically housed in the Local Exchange or Central Office, the B-RAS can also be responsible for IP address allocation and termination of PPP links. In modern DSL networks, it is not uncommon to see the functionality of a B-RAS contained within an IP – DSLAM.
