These digital lines could be copper lines. It was designed to move outdated landline technology to digital.

ISDN connections have a reputation for providing better speeds and higher quality than traditional connections. Faster speeds and better connections allow data transmissions to travel more reliably.

The modern upgrade to an ISDN would be using a SIP trunk provider — they use the data for business phone service to a PBX.

History of ISDN

ISDN was born out of necessity. Analog phone networks failed constantly and proved to be unreliable for long-distance connections.

Sometime in the 1960s, the system began to change over to a packet-based, digital switching system.

The UN-based International Telecommunications Union, or ITU, started recommending ISDN in 1988 as a new system for operating companies to deliver data.

It still took time for communication providers to begin to offer ISDN. This was mainly because both major companies at the time were on separate operating systems. By the 1990s, the National ISDN 1 (labeled N1-2 for short) was created.

While this innovation could improve the quality of communications, an agreed-upon standard still took time to figure out.

Finally, manufactures like Motorola and USRobotics decided to make the transition easier for everyone.
