What is a Circuit-switched Telephone System?

So, what exactly is a circuit-switched telephone system?

Mostly, you have a single line that allows you to make calls as well as receive them.

You have a connection which is dedicated to and between one endpoint and another in your network.

This is known as a ‘POT’ or Plain Old Telephone System.

When you make a call, you can’t accept another one or be disturbed, making it closed off.

There is also no way of knowing that someone has tried to ring you, which often causes problems when you have missed an urgent call.

It uses copper wires that transfer voice data, which is the most frequently used system that is used in most residences today.

During the time of old-fashioned dial-up connections to the internet, you couldn’t make a call and use the internet at the same time.

As in modern times, you no longer need to use your telephone line as a dedicated internet connection; there are questions as to how relevant circuit switching is.

Packet-Switched Telephone Systems

A more modern method is packet-switching.

Your call will be cut up into packets of data, which is then transmitted through your network to the person at the end of your line – this is often cheaper, although the quality can sometimes suffer if you don’t have exceptional broadband.

This is especially true if you have multiple callers at once, or on the line.
