The signal distribution over several lines is performed by telephony switches. This analog copper-based telephone network is ultimately connected with a PBX box, which enables analog voice data transmission over multiple telephone lines.

It was primarily operated by telephone operators. PThe traditional PBX phone system used copper-based telephone lines that relied on complicated analog switches and connectors. The following features are offered by a PBX phone system. In the business-centric environment, PBX phone systems are chosen over POTS phone systems due to their exceptional features. Currently, Voice over IP (VoIP) technology is implemented to the PBX phone system for fast yet secured enterprise-centric communication. For the external user connection, PBX converts analog data to digital data or vice versa. Further, it evolved into an external connectable network using the POTS phone system. Initially, the PBX phone system was developed to offer a private network for analog signal transmission for the office spaces. It saves the cost of acquiring an individual line for each communication device. Unlike the public switched telephone network that is the POTS phone system, the PBX phone system allows multiple connections via a single telephone line. PBX phone systems can be used with copper cable connection, analog, and digital combination transmission-lines, and voice over IP (VoIP). It can be used over copper cable connectivity and with the IP transmission media as well. It is a private business telephone system adopted by the organizations to establish a secure communication channel.
