The Public Switched Telephone Network (PSTN) is primarily based on three topologies: the star topology, the ring topology, and the mesh topology. In a star topology, all devices connect to a central hub or switch, facilitating straightforward communication. The ring topology connects devices in a circular fashion, allowing data to pass in one direction, while the mesh topology offers multiple pathways between nodes for redundancy and reliability. Each topology serves distinct purposes in the overall structure of the PSTN.
what are the different networking topologies?
I think PSTN mainly serves to wired land-line(telephone) and MSC serves to cellular(mobile) network.
Network topologies are connected through various physical and logical arrangements of nodes (devices) and the links (cables or wireless connections) that join them. Common types include star, ring, bus, mesh, and hybrid topologies, each dictating how data travels between nodes. For instance, in a star topology, all nodes connect to a central hub, while in a mesh topology, each node connects to multiple others for redundancy. The choice of topology affects network performance, reliability, and scalability.
Even the smallest LAN technically has a backbone, which could be any of the 4 basic topology types. Any time you need to connect various routers, switches, etc., together you connect them via a backbone cable. A backbone may have its own topology as well,such as a serial bus, parallel, distributed, or collapsed backbone. These topologies do not exactly mirror topologies for a LAN or a WAN.

PSTN will convert the digital signal from VoIP into voice signal. Their networks interacts using satellite frequency.
what are the different networking topologies?
Ring, Star, Bus, Mesh.
By the way, call from VOIP can be received by pstn modem. But pstn cannot make a call to VoIP number.
PSTN stands for a public switched telephone network. A PSTN gateway is hardware components that third parties use to translate signaling.
Ring, Star, Bus, Mesh.
ISDN is dial up lines and PSTN is a broadband line.
Logical topologies consist of virtual connections between nodes.
Star topologies. Sometimes combined topologies are used of which i have no idea!! :P
Mesh topologies and SONET rings.
Those are the topologies - star, bus, and ring (that is their name).
The best topology, whether it is a LAN based or a WAN based topology, is the one best suited for your environment. There is no one best topology for all situations.
