A PRI – or Primary Rate Interface – is an end-to-end, digital telecommunications connection that allows for 23 concurrent transmissions of voice, data, or video traffic between the network and the user. The PRI line, or circuit, is a physical piece of equipment.

Seamless connections that evolve with growing needs are the need of the hour. With the flexibility to upscale to any bandwidth, PRI is here to transform business connectivity. PRI services provide a full featured, 2-way connectivity between ISDN compatible PBX or Key System and the Public Switched Telephone Network (PSTN).
