Analogue & Digital Services
BT to end ISDN and PSTN services by 2025
It’s been more than five years since BT announced they’d be turning off analogue PTSN and ISDN services in their entirety by 2025. (Indeed they have now stopped taking new orders for these.)
This decision is both driven by cost-saving considerations and a desire to increase functionality.
So communications technology is definitely shifting towards an exclusively digital capability, and it’s understandable that you may be wondering what the implications of the move are for your business.
In particular, smaller organisations using landline telephony and faxes will need to have alternative arrangements in place to keep their systems operational, but the decision from the telecoms giant is set to affect some two million businesses in all.
First of all – what are ISDN and PSTN?
- ISDN, or Integrated Service Digital Network, has been around since 1986 and is a circuit-switched phone network providing data and voice services via digital lines. Initially, it was considered to be an up-to-the-minute solution which migrated outdated landline technology to the digital arena and allowed for the then fastest web connection at 128kbps. It also meant that data could be sent more speedily than previously, with very few issues from distortion.
- PSTN, or Public Switch Phone Network, is a traditional analogue solution, sending information via copper lines which are now being phased out.
What advantages does VoIP offer?
Many bigger organisations have already made the transformation this modern, progressive tech, whose benefits include:
- You can access it with just an internet connection
- You need fewer phone lines, so there are cost savings to be made
- When you do need new lines, these can be installed at speed
- Flexible scalability means that if you have a cloud-based phone solution coupled with a SIP line (this stands for Session Initiation Protocol an is essentially a way of making and ending connections for online voice and data transfers), VoIP means you can easily transfer calls between locations such as different offices while using the same line wherever you are in the country.
- You’ll be able to see which team members are free to take or make calls
What’s the alternative?
In an era of Wide Area Network (WAN) and Digital Subscriber Line (DSL) technology, both PSTN and ISDN have become outdated solutions.
BT has invested extensively in Voice Over Internet Protocol (VoIP), allowing all services to be migrated to Internet Protocol (IP), so the demands of all businesses can be better met in future.
Preparing for the big switch-off
As we mentioned, analogue solutions ISDN and PSTN are to become redundant by 2025. And while you still have a few years in hand, it makes sense to prepare for the changeover now.
Particularly, for example, if your phone contract is due to be renewed, now is a good time to make the switch and begin looking into VoIP alternatives, which will allow you to manage your phone solution via a cloud-hosted online control panel.
What you need to do
- Do a thorough audit of your business needs
- Talk to communications specialists about available options
- Make sure you have the bandwidth for the VoIP solution as well as all the other things your business uses the internet for – the last thing you want is a patchy service or poor-quality audio
