What is Digital Line?

An umbrella term for various kinds of digital telecommunications services. The distinguishing feature of a digital line is that it is digital from end to end and does not employ any kind of analog modem technologies.

As a result, digital lines have higher traffic-carrying capacities, less noise, and better error-handling features than analog lines.

The term “digital line” can refer to circuits based on the following:

  • Digital data service (DDS)
  • Integrated Services Digital Network (ISDN)
  • T-carrier services such as T1 lines, fractional T1, and T3
  • Switched 56 services
