# B-ISDN - Broadband-ISDN

**Broadband Integrated Services Digital Network (B-ISDN)** is a high-speed communication system designed to support a variety of digital services such as voice, data, and video over a single network. 

It uses advanced transmission technologies like fiber optics and Asynchronous Transfer Mode (ATM) to deliver higher bandwidth and improved quality of service compared to traditional ISDN. 

B-ISDN facilitates a wide range of multimedia and high-bandwidth applications, making it suitable for both business and residential use.
