Redstone, later Unisphere, eventually was acquired by Juniper from Siemens. It helped lead the way in large-scale, high-bandwidth, wire-speed broadband access devices with the ERX platform. With devices scaling into many gigabits per second, and with support for hundreds of thousands of simultaneous subscribers with rich functionality, the Juniper ERX platform is widely deployed. It is slated for use in many next-generation triple-play networks. DSL FORUM BROADBAND ACCESS DEVICE REQUIREMENTS With standardized user access protocols such as RADIUS and TACACS, advanced DSLAMs, and other supporting technologies available, the DSL Forum began specifying requirements for broadband access servers along with their architecture descriptions.
