PRI Trunking


PRI (Primary Rate Interface) is a voice technology that has been widely-used since the early 1980′s. It is an interface standard used on an ISDN (Integrated Services Digital Network) to deliver multiple lines of voice and data into a business’s exiting PBX via one physical line, called a circuit. PRI is a high-capacity service carried on T1 trunk lines between telecommunications central offices and your location. Most businesses have their PRI circuits in the form of T1 or fractional T1 lines. A T1 line carries voice and data via 24 digital channels.

This technology is sometimes considered “old-school” telephony by virtue of its physical hardware which often requires servicing from a telecommunications company for deploying, upgrading and troubleshooting.  The benefit of this type of circuit are that its often touted as the more secure telecommunications method as traffic travels through a private telephone network.

Benefits of a PRI

PRI circuits always have a guaranteed amount of bandwidth set aside for each call that cannot be used for any other purpose thus ensuring a high level quality of service.  Please speak with a representative at Vive Communications to determine if a PRI is the right fit for your company.
