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

Public Switched Telephony Network
what is the difference between khadi and handloom

What is difference between public ip and isdn
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.
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.
I think PSTN mainly serves to wired land-line(telephone) and MSC serves to cellular(mobile) network.
Packet Switch Data Network
PSTN stands for a public switched telephone network. A PSTN gateway is hardware components that third parties use to translate signaling.
By the way, call from VOIP can be received by pstn modem. But pstn cannot make a call to VoIP number.
Cellular Telephones is using the Integrated Services Digital Network ISDN while the Cordless Telephone is using the Public Switched Telephone Network PSTN, same with ordinary telephone.
