PBX Vs. PABX. Is There Really A Difference?

The world of telecoms can be a tricky one. Websites all over seem to give a lot of information on their products, but it’s seldom the information you actually need. At Telviva, we want to simplify your life, not confuse it, so we thought we would break down a small question that some of our customers and clients have been asking us; “What is the difference between a PBX and a PABX?”

The first obvious thing, is the introduction of that little ‘a’.  In a nutshell, PBX stands for Private Branch Exchange, and PABX stands for Private Automatic Branch Exchange. The word ‘Automatic’ gives a hint as to how the two differ from each other. Basically, a PABX is a type of PBX that is simply automated.

In it’s earliest days, a PBX was a room in which switchboard operators could connect calls from one caller, to another, by manually plugging wires to complete a call circuit. As technology evolved, new improvements were added – one of these being the advent of electronic switching. Hello automation! The introduction of this meant that a newer term for PBX was needed, and so it evolved from PBX to PABX. We have come a long way from operators in a room, and today all PBX’s are automated, which means there’s really not much need to differentiate between a PBX or a PABX.

Because of this, the terms PABX and PBX are used interchangeably as they basically point to the same system.

The technology didn’t stop there, though, and PBX’s are now so feature rich that standard offerings on them now include the likes of call conferencing, call waiting and so much more.

With a Telviva PBX, the future is even more accessible, as our PBX’s are hosted in the cloud, meaning better security, better speed, reduced costs and less downtime. No more old ladies in a dark room!   In conclusion, PABX is just one type of PBX and nowadays both mean the same thing. So, there you have it.
