Business Class PRI Overview

 

Business Class PRI Tech Specs

Business Class PRI is a commercial ISDN trunk service that uses Internet Protocol (IP) technology to deliver data packets of voice signals over our fiber-rich network. It then converts the signaling to DS‐1 and provides PRI service via a voice gateway located at your business location. Your calls are never routed over the public Internet.

Our voice‐only, IP‐enabled service is delivered over our fiber-rich network. A single Business Class PRI offers customers a two‐way trunk with the ability to make and/or receive up to 23 simultaneous calls. The product provides customers with the standard ISDN PRI configuration of 23 B channels for voice communications and a D channel for signaling (e.g., 23B+D), as well as other fractional PRI service configurations.
