Saving internal communication costs, good security, integrating VoIP links between branches, installing automatic greetings, etc. are the indispensable advantages of Analog PBX . So what is Analog technology? What parts or equipment does it include? And what are the pros and cons? Let’s find out through this article!
1. What is Analog PBX?
Analog is a type of telephone exchange that appeared about 20 years ago, operating based on Analog technology. Accordingly, Analog technology operates through the postal line. Specifically, when customers register to use the service, the post office will pull the line to the company’s office. You will have to equip hardware equipment, divide it into extensions to different departments if you want to use Analog PBX.
The concept of Analog PBX
2. Structure of an Analog PBX system
- Input signal: This signal is provided by the post office to the Analog switchboard. The input audio signal is converted into electronic waves with different amplitudes and frequencies, and then sent to the other end of the wire. Analog phone systems use CSN (Circuit Switching Network) technology to transmit signals over serial wires, creating a conversation.
- Switches: The number of switches is set up depending on the needs and scale of use.
- Terminal: The terminal is a landline phone. The service provider will assist you with wiring to each location, configuring the internal switchboard, and recording if needed.

4. Working principle of analog PBX
Analog PBX is equipped with a switch hook (Switch Hook), which attaches to the phone line. When the switch hook is detached, the phone line connects to the system’s transmission circuit.
When dialing from an Analog phone, the transmitter sends an electronic signal. The call converter will then act as a signal converter, converting the signal into a message to send to the other end of the line.
