A PSTN subscription refers to a service agreement that provides access to the Public Switched Telephone Network. This network enables users to make and receive telephone calls over traditional analog or digital phone lines. A PSTN subscription typically includes a phone line, local and long-distance calling capabilities, and sometimes additional features such as voicemail or caller ID, depending on the service plan.
What is a PSTN connection?
A PSTN connection is a telephone line that connects to the Public Switched Telephone Network, allowing users to make and receive voice calls. This connection can be either analog or digital and uses traditional copper telephone lines or more modern digital lines to route calls through the network. PSTN connections provide reliable voice communication services and are widely used for residential and business telephone services.
PSTN stands for Public Switched Telephone Network, which is the traditional network used for telephone communication. It includes a vast system of interconnected telephone lines, switches, and exchanges that handle the routing of voice calls between different locations. PSTN is based on circuit-switching technology, which establishes a dedicated circuit for each call, ensuring reliable voice communication.
The PSTN was invented in the late 19th century, with its development starting around 1876 when Alexander Graham Bell invented the telephone. The network evolved over the years, incorporating various technologies and infrastructure improvements. The basic principles of PSTN have remained consistent, providing a foundation for voice communication for over a century.
