What does PSTN mean?

Once again, another acronym, so let’s get that out of the way. PSTN stands for Public Switched Telephone Network.

So what does it mean?  It is simply a phone line from your premises to the exchange. Then you are connected to the rest of the PSTN. Excited ?

Once at the exchange this is where all the switching gets done i.e. connected to the next network until it reaches the phone where the destination number is.
Of course all of this routing happens in a split second and in fact is 99% digital today.

However the last hop on the journey is still using a physical copper line from your office or home to the nearest junction box which is the hop between you and the exchange. 

So it’s a big network that enables you to be connected to other people on the network.

The network today is owned by governments and large telecoms providers and extends all over the world through the air and under the oceans. This is why you are billed monthly or quarterly for this service so it can be maintained and improved.

We also use the PSTN line for most broadband connections today and interestingly knowing where we access data from and accessing those entire networks worldwide we only pay a single fee to our broadband supplier. Quite impressive when you think about it.
