“PSTN” means “Public Switched Telephone Network,” and “ISDN” means “Integrated Services Digital Network.” One of the main differences that can be seen between the two is that PSTN lines are analogue while ISDN lines are digital. PSTN has a disadvantage that it does not make the most possible use of the broadband.

What is ISDN card?

ISDN or Integrated Services Digital Network is a circuit-switched telephone network system that transmits both data and voice over a digital line. You can also think of it as a set of communication standards to transmit data, voice, and signaling. It was designed to move outdated landline technology to digital.

What happened to ISDN?

With BT Wholesale having announced that from 2020 you will no longer be able to purchase Integrated Services Digital Network (ISDN) and public switched telephone network (PSTN) circuits as it targets a 2025 switch off date, questions are naturally being asked.

What is PSTN and DSL?

DSL stands for Digital Subscriber Line. It is a term used to describe a range of high-speed (broadband) communications services offered over the Public Switched Telephone Network (PSTN). The PSTN uses a pair of copper wires to connect your telephone service to the national telephony network.

How do I connect to PSTN?

In order to connect your VoIP system to the PSTN you will need an FXO gateway. There are a number of manufacturers who sell FXO gateways. You can get a complete list of them here. An FXO VoIP gateway works as a bridge between your IP network and the PSTN.

Does VoIP use the PSTN?

The VoIP calls can be made from one phone to another or from a computer to a phone. Public Switched Telephone Network (PSTN), on the other hand, uses circuit-switched telephony between two points for the duration of a call. VoIP uses the internet to connect but PSTN uses a landline.
