Therefore, I am going to explain to you in simple, easy to understand terms exactly “What Is a PRI” without all of the ‘tech talk’   For further details you can select What Is a PRI.

At its most basic level a PRI is the Integrated Services Digital Network (ISDN) equivalent of a T1 circuit.

However, in order to easily understand what a PRI is it’s just easier to think of it as twenty-four (24) ‘things’.  And it’s surprising to find out what those things can be, such as; a telephone system (traditional PBX or VoIP), a modem, telephone line, video, off premise data, an alarm line, or even your Internet service.

What is a PRI circuit that is used for voice:  If you are utilizing a PRI 100% for digital phone service, afterwards you will receive 23 digital telephone lines which can all be utilized concurrently (known as ‘B’ channels), and the 24th line (named a ‘D’ channel) is used for signaling info (ensuring that once someone hangs up - the line disconnects and is totally free to be used immediately) and unique features, like; caller ID, DID (Direct Inward Dialing), which allows a telephone number to bypass the Operator, or voice mail system and goes immediately to a particular person or a department, such as sales or service.

What is a PRI circuit that is used for data:  A PRI has a speed of 1.544 Mbps when it is used 100% for data, and each individual channel (of which there are 24) has a speed of 64 Kbps.

What is a PRI circuit that is used for both voice and data: The flexibility of a PRI circuit is what makes it so unique.   Therefore, if you remember our original statement from above that a PRI is ’24 things’, one can set it up your circuit in a wide variety of methods.  For example, you may have a PRI that has 12 circuits for voice, offering you 12 simultaneous phone calls, and 12 circuits for data, providing you a speed of approximately 768 Kbps which could be used for Internet service.  For more detailed information on PRI circuit configurations you can go to What Is a PRI Line.
