PSTN (Public Switched Telephone Network) refers to the traditional circuit-switched telephone network that has been used for decades to facilitate voice communications. It connects calls through a series of physical wires, switches, and exchanges, allowing users to communicate over long distances. PSTN primarily supports landline telephones, but it also incorporates cellular networks and VoIP services in modern implementations. Despite the rise of digital communication technologies, PSTN remains a crucial infrastructure for many types of voice communication.
PSTN stands for Public switched telephone network PSDN stands for Public switched Data network / Packet Switched Data Network. The basic difference between two is the switching technique used. PSTN uses Circuit Switching and PSDN uses Packet Switching

Yes, PSTN (Public Switched Telephone Network) can be implemented on 3G networks through a technology called circuit-switched fall-back (CSFB) or Voice over IP (VoIP) solutions. CSFB allows voice calls to be routed through the traditional PSTN when a 3G network is used for data services. Additionally, operators can use VoIP over the 3G network to connect to PSTN, enabling seamless communication. However, the efficiency and quality of the implementation can vary based on network infrastructure and technology used.
In telecommunication gateways refer to the gaps through which the communication travels. They are not usually literal gaps but they are the routes used with a means of being blocked at the gateway.
