I think PSTN mainly serves to wired land-line(telephone) and MSC serves to cellular(mobile) network.

What is a difference between pstn and isdn?
PSTN is Public-Switched Telephone Network ISDN is Integrated Services Digital Network. PSTN is followed by ISDN, chronologically. <p><p> The difference between PSTN (Public-Switched Telephone Network) and ISDN (Integrated Services Digital Network: First, they must be explained, and in chronological dating, these technologies can be understood: *Some PSTN History: The PSTN was the earliest example of traffic engineering to deliver Quality of Service (QoS) guarantees. A.K. Erlang (1878-1929) is credited with establishing the mathematical foundations of methods required to determine the amount and configuration of equipment and the number of personnel required to deliver a specific level of service. PSTN: In the 1970s the telecommunications industry conceived that digital services would follow much the same pattern as voice services, and conceived a vision of end-to-end circuit switched services, known as the Broadband Integrated Services Digital Network (B-ISDN). The B-ISDN vision has been overtaken by the disruptive technology of the Internet. Only the oldest parts of the telephone network still use analog technology for anything other than the last mile loop to the end user, and in recent years digital services have been increasingly rolled out to end users using services such as DSL, ISDN, FTTP and cable modem systems. Many observers believe that the long term future of the PSTN is to be just one application of the Internet - however, the Internet has some way to go before this transition can be made. The QoS guarantee is one aspect that needs to be improved in the Voice over Internet Protocol (VoIP) technology. There are a number of large private telephone networks which are not linked to the PSTN, usually for military purposes. There are also private networks run by large companies which are linked to the PSTN only through limited gateways, like a large private branch exchange (PBX). ISDN Integrated Services Digital Network (, originally "Integriertes Sprach- und Datennetz" (German for "Integrated Speech and Data Net"), is a circuit-switched telephone network system, designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better voice quality than an analog phone. It offers circuit-switched connections (for either voice or data) in increments of 64 kbit/s. One of the major use cases is Internet access, where ISDN typically provides a maximum of 128 kbit/s. More broadly, ISDN is a set of protocols for establishing and breaking circuit switched connections, and for advanced call features for the user. It was introduced in the late 1980's.[1] In a videoconference, ISDN provides simultaneous voice, video, and text transmission between individual desktop videoconferencing systems and group (room) videoconferencing systems. [edit] ISDN elements * Integrated Services refers to ISDN's ability to deliver at minimum two simultaneous connections, in any combination of data, voice, video, and fax, over a single line. Multiple devices can be attached to the line, and used as needed. That means an ISDN line can take care of most people's complete communications needs at a much higher transmission rate, without forcing the purchase of multiple analog phone lines. * Digital refers to its purely digital transmission, as opposed to the analog transmission of plain old telephone service (POTS). Use of an analog telephone modem for Internet access requires that the Internet service provider's (ISP) modem converts the digital content to analog signals before sending it and the user's modem then converts those signals back to digital when receiving. When connecting with ISDN there is no analog conversion. * Network refers to the fact that ISDN is not simply a point-to-point solution like a leased line. ISDN networks extend from the local telephone exchange to the remote user and includes all of the telecommunications and switching equipment in between. The purpose of the ISDN is to provide fully integrated digital services to the users. These services fall under three categories: bearer services, supplementary services and tele-services.
What is the purpose of pbx in a hotel?
The purpose of a PBX system in a hotel will be the same in any other businesses that utilizes it. The main function of a PBX system is to provide connections to all the internal telephones and PSTN networks or lines. In short it is use for the management and control of incoming and outgoing phone calls.

What is the need of having a GMSC in GSM network when there is an MSC?
A normal MSC will connect BSC to the PLMN/PSTN Network directly. Meaning to say it will need to do the call connections and management from BSC all the way to PLMN/PSTN network. Once the network expands, the MSC will face congestion and therefore a solution needed. GMSC - Gateway MSC, as the name implies, will in this case serve as an interconnection between MSC and PLMN/PSTN Network. Thus this free up the resources of the MSC itself need to perform all the originally tasks.
What is the difference between PSTN and PLMN?
pstn is for wired network plmn is for mobile network

What is a difference between pstn and psdn?
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
What is difference between MSc in operation management and MBA in operation management?
The difference between MSc in operation management and MBA in operation management is that MSc in operation management leads to a general manager while the latter leads to an operations manager.
What is the differnece in how voice is transmitted over a PSTN and how voice is transmitted over an IP network?
The difference: With PSTN, the voice is transmitted through the network of cables. While with VoIP is transmitted through the internet. This is the main difference between the two communication systems.
The difference between PSTN and ISDN in hsdpa?
WHAT IS THE DIFFERENCE BETWEEN ISDN AND PSTN ? The PSTN is the Public Switched Telephone Network and is therefore a service provided by a telecommunications company. The ISDN is the Integrated Services Digital Network and is a technology, providing digital end to end connectivity. However, calls originating from an ISDN site, will transverse the PSTN in order to be received by the called party. The call received by the called party, may be digital, if they also have ISDN service, or the call may be converted by the central office to meet the technology being used by the receiving party.
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.
