A PRI (Primary Rate Interface) line is a type of digital telecom connection used primarily by businesses to handle multiple voice, data, and video transmissions over a single line. It’s part of the ISDN (Integrated Services Digital Network) standard and is especially useful for organizations that need to manage a high volume of simultaneous calls.
Here’s a quick breakdown of how it works:
- A PRI line typically offers 23 voice channels and 1 signaling channel on a T1 line (or 30 voice + 1 signaling on an E1 line, common outside North America).
- It connects your business’s PBX (Private Branch Exchange) system to the telecom provider’s network.
- It’s known for reliable call quality, dedicated bandwidth, and low latency, making it ideal for call centers, hotels, and enterprises.
While PRI is considered legacy tech today—largely replaced by VoIP—it still has niche advantages like better stability during internet outages and consistent performance in areas with poor internet connectivity.
