Phone System Wiring & Setup in Minneapolis
A telephone is a telecommunications device that permits two or more users to conduct a voice conversation at long distances. This device converts sound into electrical signals suitable for transmission via cables over long distances, and replays those signals simultaneously in audible form to the user. A traditional landline telephone system, also known as "plain old telephone service" (POTS), generally carries the audio signals on a twisted pair of insulated wires.
The invention of the transistor in 1947 conclusively changed telephone technology and the transmission networks that it used. With the development of electronic switching systems in the 1960s, telephony began its evolution into the digital domain which improved the capacity and quality of the network. Further development of protocols used for the internet made it possible to digitize voice and transmit it as real-time data across computer networks, giving rise to Voice over Internet Protocol (VoIP). Traditional telephone network infrastructure was quickly and quietly being pushed into obsolescence.
Prior to the digital age, the use of a physical pair of wires for anything other than the transmission of speech was not considered. However, as long-distance nodes were gradually converted from analog to digital operation, the idea of being able to pass data through them by utilizing frequencies above the voiceband took hold, ultimately leading to DSL.
DSL (Digital Subscriber Line) is a technology that is widely used to provide internet access by transmitting digital data over telephone lines. DSL service is delivered simultaneously with wired telephone service on the same line. Higher frequency bands are utilized for data, making this possible. DSL filters on each non-DSL outlet block any high-frequency interference to enable simultaneous use of the voice and internet services.
With the proliferation of cellular communications in today’s world, usage of the telephone system has shifted from voice calls to internet access, and as such, phone wiring has once again become viable in many home and business endeavors.
