IPTV Business terms

1. dslam (DSL access Multiplexer): digital user line access multiplexing, that is, a modem combination connected to a multi-channel compound system center. It collects signals from multiple DSL connections and converts them to a high-speed line, it is used to support video, broadcast and television, fast Internet access, and other high-value applications. DSL line connections use a combination of ATM, frame relay, or IP networks. The features include optimized transmission rate, aggregated links to optimize bandwidth utilization, and traffic control capabilities.

2. Bras (broadband remote access server): A Broadband Access Server that provides enhanced security for your internet access. After the user passes authentication, the Broadband Access Server (BAS) sends the billing start package to the backend RADIUS server, after a User goes offline (the user hangs up, crashes abnormally, and the network is disconnected), Bas sends the billing end package to the backend RADIUS server. The bras device in the Operation Management stage should not only improve the user's access authentication and billing functions, but also act as the service gateway. It should work with the business management platform to provide value-added services and online application services. However, bras needs to implement personalized management and services for users, provide rich value-added services, ensure the security and order of broadband network operations, and avoid account theft and other problems, the most fundamental factor is that users must be identified accurately. This is one of the important reasons why value-added broadband MAN services cannot be implemented.
