ISDNalapú

ISDNalapú is a Hungarian term that translates to "ISDN-based". It refers to services, systems, or technologies that utilize the Integrated Services Digital Network (ISDN) as their underlying infrastructure. ISDN was a telecommunications standard that allowed digital transmission of voice and data over existing telephone lines. It offered higher speeds and more features compared to traditional analog telephone lines.

Therefore, when something is described as ISDNalapú, it means it operates using ISDN technology. This could include applications like ISDN telephone lines, ISDN modems, or specific data transmission services that were built upon the ISDN network. While ISDN was a significant advancement in its time, offering simultaneous voice and data transmission and faster connection speeds, it has largely been superseded by newer technologies such as DSL, fiber optics, and mobile broadband. However, the term ISDNalapú might still be encountered in contexts referring to older systems or in historical discussions of telecommunications evolution. Its primary significance lies in representing a step towards the fully digital communication networks that are prevalent today.
