ISDN
ISDN (Integrated Services Digital Network) is a professional-quality phone line system commonly used in radio broadcasting for remote interviews and live broadcasts. Think of it as a special phone connection that provides much clearer sound than regular phone calls. Radio stations use ISDN because it delivers studio-quality audio, making remote guests sound like they're in the same room as the host. While newer internet-based technologies are becoming more common, ISDN is still mentioned in many broadcast job descriptions because some established stations and studios continue to rely on this trusted technology.
