Embracing the switch to IP

BLACKBURN, England -


The Public Switched Telephone Network (PSTN), is an analogue phone network used in the UK by businesses and households as a connection to make phone calls, receive emails, and browse the web. It has served the UK for generations, but the technology is now becoming obsolete, and a new system is required to meet our communication demands. Andrew Collinson Operations Director for Electronic Security at Chubb shares his insights on how the switch will affect those businesses with security systems in place.

As a ‘last century’ technology, the PSTN network is increasingly unable to deal with the demands of modern communications and no longer sustain the amount of data being shared. As more people switch to mobile and internet communications, our use of these technologies broadens, and our world gets faster. Consumers expectations of performance are therefore much greater than the traditional technologies were once designed to deliver. The new IP system will present new digital ways of working and opportunities to change how we communicate.

Who will be affected?
Businesses and individuals in the UK will be affected if they have a PSTN phoneline. Openreach (the business responsible for telephony transfer in the UK) will be switching to a digital IP (internet protocol) based system shortly, so many of the devices designed to operate on the old PSTN system will not work. For businesses, this could mean EPOS devices don’t work, faxes certainly won’t operate, and in the security sector; alarms, CCTV and access control solutions many not function, leaving people unprotected
How can you prepare for the switch?
The first step is not to panic. The switchover has already begun, but is due to continue until the end of 2025, when the PSTN network is closing and the all IP network will be fully operational in the UK. This will signal the beginning of a new era in communications technology. Although support for the network with not be withdrawn until 2025, businesses and customers need to plan now and review their communication technology and find out how they will be affected by the changes. Those who wait until the last minute to make the change are likely to experience delays and find it difficult to get faults fixed. 
Service providers such as BT and Redcare are a great source of information and will be happy to help their customers. They will also be able to offer solutions which are compatible with the new IP system to ensure continuity resulting in minimal disruption to the business.
Faster with more features
The switch is a positive change as these digital systems are faster and boast far more features than you may be used to. When used with latest generation security products, they can easily integrate with mobile devices and apps, provide detailed reporting, and help gather insights about customer and employee behaviour.
