What Is An Integrated Services Digital Network (ISDN)?
An integrated services digital network (ISDN) is a circuit-switched telephone system that can transmit voice, data, and video over digital lines. It was created to migrate landline technology to digital and provides the “dial-up” service used for non-broadband internet connections. ISDN offers more speed and reliability compared to traditional connections. Today, broadband internet lines like DSL, WAN, and cable have mostly replaced ISDN.
Benefits of ISDN
Here are some of the benefits of an ISDN:
Supports high-speed internet when DSL or cable is not available
Can be used as a failsafe for DSL/WAN lines
Can connect devices and enable them to work over a single line
