A PRI line is an end to end digital circuit. It was one of the most widely used technologies for business communications and services.

A PRI circuit consists of two pairs of copper lines terminating on a modem from a service provider's premises to the customer premises. It uses multiplexing/de-multiplexing techniques to carry multiple channels in a single circuit. Each channel in a PRI line provides 64 Kbps for data transmission.

There are two common forms of PRI lines – E1 (which carry 30 channels in the two pairs of copper lines, common in Europe, India) and T1 (which carry 23/24 channels in the two pairs of copper lines, common in the United States).
