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 is the difference in the working of MSC and PSTN?
I think PSTN mainly serves to wired land-line(telephone) and MSC serves to cellular(mobile) network.
How are network topologies connected?
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.
What are the different types of media in PSTN?
In a Public Switched Telephone Network (PSTN), the primary types of media used for voice communication include copper twisted pair cables, which are the most common for residential phone lines, and fiber optic cables, which provide higher bandwidth and quality for long-distance communication. Additionally, coaxial cables are sometimes used in hybrid networks that combine telephony and internet services. Satellite links can also be part of PSTN infrastructure, particularly for remote areas. Each medium has its own characteristics in terms of bandwidth, distance, and signal quality.
What topology is used in local area networks?
Local area networks (LANs) commonly use several topologies, with the most prevalent being star, bus, and ring topologies. The star topology connects all devices to a central hub or switch, facilitating easier management and fault isolation. The bus topology involves a single central cable to which all network devices are connected, while the ring topology connects devices in a circular format, where data travels in one direction. Each topology has its advantages and disadvantages, influencing its selection based on network size and requirements.
Describe how a network based VoIP provider interacts with the PSTN?
PSTN will convert the digital signal from VoIP into voice signal. Their networks interacts using satellite frequency.

How can you get a pstn modem to answer calls from a voip system?
By the way, call from VOIP can be received by pstn modem. But pstn cannot make a call to VoIP number.
What is a pstn gateway?
PSTN stands for a public switched telephone network. A PSTN gateway is hardware components that third parties use to translate signaling.
Four types of network topologies used in wire based networks?

What is the difference between the facilities offered on a PSTN and the ISDN?
ISDN is dial up lines and PSTN is a broadband line.
What is true concerning physical and logical topologies?
Logical topologies consist of virtual connections between nodes.
What kind of topologies are good choices for highly available enterprise networks?
Mesh topologies and SONET rings.
What kind of network do schools use?
Star topologies. Sometimes combined topologies are used of which i have no idea!! :P
