PSTN stands for Public Switched Telephone Network, which is an acronym to describe the copper cabling in your building which delivers voice and DSL internet services from your service provider, the term is almost identical to the other reference which is POTS (Plain Old Telephone Service). These services are delivered to your property using a cable that contains a pair of copper wires and is presently used for telecommunication for both residential and commercial customers in Ireland. These lines generally connect from your property and travel under or overground a few hundred meters back to a local service cabinet and from the service cabinet there is then a fibre backhaul link that connects the cabinet to the ISPs core network. These systems are known as FTTC (Fibre to the cabinet)

Phone Line Problems

The above services can also be delivered directly to your building via a fibre optic cable which is terminated directly inside your property, this is known as FTTP (Fibre to the Premises), while there are many advantages for choosing fibre over copper based systems, in the case of residential customers if there is a power cut this typically stops the service operating in the home which means the internet and landline services go down during the power outage while commercial customers will often have a backup battery system (UPS) that will keep the service online. The cables used in optical systems are prone to damage and are quite fragile so we often recieve calls from the public to repair fibre optic broadband where the customer has damaged the cable and need a quick repair service.

What's the difference between FTTP and FTTC?

The difference is that with FTTP (Fibre To The Property) the fibre optic cable travels from your service provider's network directly into your property and with FTTC (Fibre To The Cabinet) The fibre cable only travels as far as your local telecoms cabinet and then uses the existing coper cables that are already installed to connect to your property. This limits the bandwidth available to you is capped and it means you cannot achieve the performance that is available with FTTP.
