In 2015 Openreach<\/a> announced they would be switching off their entire analogue public switched telephone network (PSTN) and transitioning to a digital infrastructure by 2025. This marks the biggest change to the telecoms industry for more than 30 years, when dial up internet connections were replaced by ADSL broadband.\u00a0<\/span><\/p> Naturally, you\u2019re going to be wondering what this means for you, how it will affect your connectivity and what you need to do to ensure you remain connected. The good news is that this is still 2 years away, so there is plenty of time to prepare. In the meantime we will answer all of your questions to help you plan and ultimately switch your connection prior to the deadline. <\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t The PSTN is what you may refer to as the landline phone. It is the analogue service that was introduced by Alexander Graham Bell in the late 1800s and has been used as a way to communicate vocally with other people around the world for more than 100 years.\u00a0<\/span><\/p> It comprises a series of copper wires which allow information to be transmitted, powered by local telephone exchanges. This information is then sent through an infrastructure of exchanges and switches to enable communication between two points on the network.<\/span><\/p> The PSTN has underpinned the UK, and indeed, global communications network for most of the last century. Certainly there have been developments over the years, such as ISDN which was envisioned as a digital replacement for single, analogue landlines, but more than 90% of premises in the UK still have copper wires as their primary connecting technology. <\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t When the internet was rolled out across the UK, it made sense to use the traditional phone line network, that was already in place, to deliver it. However, consumer and commercial demand have pushed the old copper network to its limits and to meet the rising requirements for more bandwidth, the UK\u2019s broadband infrastructure needs to undergo a radical overhaul.<\/span><\/p> The reality is, the existing PSTN infrastructure isn\u2019t fit for purpose and it is no longer plausible for providers to continue investing time and money in maintaining a traditional service which has become redundant.\u00a0<\/span><\/p> Technology has advanced rapidly and fibre optic connections have been developed, which have a far greater capacity than copper lines and are much more reliable. Fibre also has the additional benefit of reducing the amount of equipment required in exchanges, driving down the costs whilst increasing the speeds of the network.\u00a0<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Firstly let\u2019s address the elephant in the room. If you are currently using the copper-based PSTN for connectivity, you will be affected by this change.<\/span><\/p> If you\u2019re not sure whether your service is copper-based, the internet connections affected are; ADSL, FTTC and Gfast.\u00a0<\/span><\/p> Full fibre connections won’t be available to everyone by the time the switch off comes in 2025, therefore a new service called SoGEA<\/a> will be available during the change over period.<\/p> Exa customers still using analogue connectivity will automatically be changed over to ensure no disruptions to your connection, however you will no longer receive a standard phone line. But, there is no need for you to panic, you\u2019ve still got time to prepare. Remember, this will be a phased approach and your services won\u2019t be switched off overnight.<\/span><\/p><\/div><\/div><\/div> Ultimately you will need to replace your copper connectivity with full fibre and install a VoIP based telephone service. This does not run over copper cables, instead voice is transmitted over your internet connection. It is important that you weigh up your options as soon as possible, so that you can be well prepared for the transition to digital.\u00a0<\/span><\/p> Here\u2019s a checklist of everything you need to do to get ready for the big switch:<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t For further information about VoIP you can read our article <\/span>‘What is VoIP?’<\/span><\/a><\/span><\/span> which covers SIP trucks and hosted services in much more detail.<\/span><\/p><\/li> Suggested<\/span> Next Read <\/i><\/span><\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\tWhat is the PSTN?<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
