PSTNközpontú

PSTNközpontú refers to systems or services that are centered around or heavily reliant on the Public Switched Telephone Network (PSTN). The PSTN is the traditional circuit-switched telephone network that has been in place for decades, connecting landline telephones worldwide.

In a PSTNközpontú context, communication and services are designed to operate within the infrastructure of the PSTN. This could include traditional landline telephony, fax machines, and certain types of alarm systems or credit card terminals that directly connect to the PSTN. Even with the rise of Voice over Internet Protocol (VoIP) and mobile communications, many services still maintain a PSTNközpontú element for compatibility, backup, or regulatory reasons.

For instance, a business might have a PSTNközpontú phone system that uses traditional phone lines for its main service. While they might also offer VoIP options, the core functionality remains rooted in the PSTN. Similarly, older emergency services or specific industrial communication systems may be designed with PSTNközpontú architecture due to its established reliability and ubiquity.

The term emphasizes a design or operational philosophy that prioritizes or originates from the established PSTN infrastructure. It contrasts with systems that are exclusively IP-based or mobile-centric. Understanding PSTNközpontú is important when discussing the evolution of telecommunications and the migration from older technologies to newer ones.
