The first difference which one can note between PBX and PABX system is that of ‘A’. PBX stands for Private Branch Exchange, while PABX stands for Private Automatic Branch Exchange. Therefore, the first difference between these two words is the presence of the word ‘Automatic’. PABX is a type of PBX that is automated. PBX is an old concept of telephony, and it started when electronics wasn’t even introduced in this field. So, calls were connected by manually connecting the wires and completing the circuit. There are other types of PBX too, but here we will discuss only PABX and PBX and the main differences between them.
Private Branch Exchange (PBX):
The Private Branch Exchange is a telephonic system that allows the enterprise users to connect to each other. They use some external phone lines by switching the calls. PBX is used as a cost efficient system, and it offers a cheap way to get a line for each user. That line used to connect to the central office of the telephone’s company. PBX is not operated by a telephone company. Instead, it is operated by an enterprise. In earlier days, PBX used analog technology, but now it uses digital technology to manage incoming and outgoing calls.
The PBX system makes communication easier within an organization by using different software and hardware technology such as telephone adapters, telephone sets, routers, switches, and hubs. Recent PBXs have many interesting and advanced features that make the communication within the organization much easier, and in turn, they boost the efficiency and productivity of an organization.
Private Automatic Branch Exchange (PABX):
A Private Automatic Branch Exchange is an automated telephonic system present inside an enterprise. PABX is a type of PBX in which all the processes are automated. Since all the PBXs these days are automatic, the term PBX has also vanished. The telephonic system mostly present inside an organization today is a PABX. The PABX system has all its features automated, and nothing like conferencing, voicemail, automatic ring back, call waiting, and internet connectivity can be done manually. PABX allows a single access number that can be used by outside callers and inside callers. This telephone system is normally used by organizations and call centers.

A PABX in Dubai provides multiple lines to the outside callers and multiple external lines to the staff or internal callers within different enterprises in Dubai. The main task of a PABX system is to perform switching that is required to make calls within the organization, and for this purpose, extensions are used.
To be precise, PBX is now an old concept and PABX is the system that is used within the enterprises as it has all the features that a PBX system has, except that it is fully automated. PBX systems, on the other hand, were manually operated. For example, the large switchboards which were used where people were used for the task of plugging and pulling the wires. Nowadays, PBX systems are known as PMBX (Private Manual Branch Exchange) systems to distinguish it from the PABXs.
