The end is near for telephony as we know it, with BT getting ready to retire its ISDN services by 2025. Don’t get left behind, start exploring alternatives today.
ISDN – What is it?
ISDN (Integrated services digital network) is a set of protocols which allow for the transmission of voice, video, and data across the vast and varying infrastructure of the Public Switched Telephone Network (PSTN). ISDN was revolutionary when it was introduced; often referred to as the ‘original high-speed broadband’ it allowed voice and data to travel across the same copper lines and introduced new, previously unavailable features to telephony when it came into effect in the late eighties.
Why are ISDN services being withdrawn?
The infrastructure on which ISDN services operate – the PSTN – is reaching the end of its useful life. Some of the ageing components of the system are proving difficult to replace as parts are no longer being manufactured and many of the individuals responsible for creating the system have retired or are nearing retirement. Additionally, with the decline of landline use in recent years the system is bringing in less revenue just as maintenance costs are increasing, making its continued operation economically unviable.
What is the PSTN being replaced with?
Over the last decade or so, Telecoms operators have been busy constructing new IP-based networks. You may not have noticed much upheaval however as not all parts of the PSTN have been replaced. In other cases, providers have installed a new IP network alongside the old network, retaining the PSTN for calls while the new IP network is used for broadband.
How should I prepare for the long-expected ISDN switch off?
You can still purchase ISDN phone lines but with the demise of the PSTN round the corner investing in traditional telephony isn’t a particularly wise move.
The transition to full IP-based networks will require all customers to adopt a VoIP service. VoIP (Voice over internet protocol) is basically the new ISDN – a group of technologies that relay voice and video across the internet.
