The History of PBX Telephony
PBX telephony systems were introduced in the early 1900s and referred to as a privately owned and operated PBX telephony network of extensions for making and receiving calls. In simple terms, PBX telephony was an in-house communication system for businesses and was manually operated by phone operators.
Eventually, with the introduction of automated switches, Private Automated Branch Exchange Systems (PABX) convinced businesses to switch their communication to PBX telephony.
PBX telephony systems have evolved to become more reliable and richer in features and benefits. Today, they are an essential part of many businesses' communication infrastructure.
What is a PBX Telephony System?
A PBX phone system is a multi-line telephone system typically used by large businesses. A PBX allows multiple people to make and receive calls at the same time without having to go through a switchboard operator.
PBX telephony systems are hardware and software that work together to route calls. The hardware includes the telephone exchange, a physical device that connects phone lines and routes rings, and strings telephone sets, which are the actual phones people use to make and receive calls. The software typically includes a control panel that allows users to manage their phone calls and features such as voicemail and call forwarding.
The most critical component of PBX telephony is the logic processor, which handles all of the call routings for the system. They also require outside telco trunks to send and receive the audio signals and a microcomputer to perform data processing. In addition, most PBX telephony systems have a protected power supply to stay operational in the event of a blackout or sudden power surge.
What types of PBX telephony are used in companies today?
PBX telephony initially required particular phones to function, but they are now compatible with almost every type of phone on the market. Most systems also have between two to eight standard phone lines and another four to eight extensions for analog or IP phones. This capacity can typically be extended for an additional cost.
The standard interface for the system tends to be either a two-wire interface, a proprietary protocol, or a DECT for cordless phones.
