The commercialization of telephones began in 1876. At that time, there were no network connections. Rather, telephones were wired in pairs for use between locations, which meant it wasn’t possible to call more than one location. People who wanted to talk to people in different locations had to have several different telephones – each with its own purpose.
In the early days, operators connected one party of a phone call to another manually, However, providers began to digitize voice calls by the 1960s and manual switching was replaced by automated electronic switching. This upgrade meant that digital voice signals could share the same wire with other phone calls. Although most people associate the PSTN with copper wiring, modern PSTN infrastructure also uses fibre optic cables. Today, services have become increasingly digital, as new infrastructure such as fibre optic cables replaces copper lines.
Telecommunications providers are transitioning from PSTN to all-IP communications. The main reason is that most carriers don’t want to manage two infrastructures – one with analogue and one with digital equipment -- when just a digital architecture can offer the same or better level of service for customers. in 2015 Openreach confirmed The Public Switched Telephone Network, or PSTN, is set to be switched off by 2025
Openreach, who manage the UK’s phone and internet network, have already began switching people over to a Cloud solution and have stated that no support will be offered for faults or repairs from 2023 & completely shut off in 2025. Once the PTSN lines have been completely switched off, people will be unable to make a traditional phone call via landline instead requiring an internet connection.
