What is TDM PBX and How it Works?
TDM PBX, or Time Division Multiplexing Private Branch Exchange, is a significant player in the realm of telecommunications. It's a system that businesses have relied upon for years to manage their internal and external phone communication. Despite the advent of newer technologies, TDM PBX remains relevant due to its stability and familiarity in the business world.
The way TDM PBX works is quite interesting. Imagine a highway where cars need to share the road. TDM PBX uses a technique called time-division multiplexing, which is like giving each car a specific time slot to travel on the road. In this analogy, the cars represent voice signals, and the road symbolizes the communication line. By precisely timing when each voice signal gets transmitted, TDM PBX allows multiple conversations to happen on the same physical line without them colliding.
TDM PBX's architecture is the backbone of its functionality. At its core is the PBX switch, a central unit that directs calls within the organization. This switch connects to various trunk lines, which are like highways leading to external networks. Businesses can connect extensions, which are like individual roads branching off the trunk lines, to the PBX switch. Each extension represents a phone line within the organization. So, when someone makes a call, the PBX switch ensures the call gets directed to the right extension or external line, enabling smooth and efficient communication within and outside the company.
