Primary Rate Interface (PRI)

PRI is a telecommunications interface used mostly in an Integrated Services Digital Network (ISDN). A PRI is a form of TDM, allowing you to send up to 23 separate communications via voice, data, or video. Channels are typically used by larger enterprise companies with a PBX system to help with access to the PSTN.
