Is It All Over For ISDN?

Tuesday, 26 September 2017

In a word, yes!

Without ISDN (Integrated Service Digital Network), the Internet revolution would not have happened as quickly. ISDN replaced slower, dial-up broadband solutions, setting the standard for data and voice communications in the 1990s. At the time, ISDN was revolutionary. But everything has its day.

Technology has taken leaps forward since ISDN was created, with the largest British communications company, BT, set to phase ISDN out by 2025. In 2016, when the competition and markets authority (CMA) cleared the takeover of EE, BT Group had 31% of the broadband market (consumers and businesses), 37.6% of the home phone market and 33.8% of the mobile market. Even after Ofcom forced BT Openreach - the network division - to split from the Group, BT will continue to exert a large influence on the communications market and the services consumers and companies can access in the UK.

Telecoms is a competitive market. Each provider - whether they offer landlines, mobiles, VoIP or unified cloud-based communications - is investing heavily in speed and security to gain market share. Hence the move, in 2015, to phase out ISDN across the BT network within ten years.

In 2020, companies won't be able to buy new ISDN circuits and services, and then, five years later, this legacy network will shut down completely. If other networks haven't followed suit, they soon will. And those that run off BT networks (or former BT wires - after the switch to Openreach) will have no choice.

Either way, ISDN is a legacy technology that can no longer keep up with modern demand.

So, what are the new options?
High-speed fibre optic broadband and cloud-based Voice over Internet Protocol (VoIP) is the future, one that many businesses are already embracing. Instead of legacy private branch exchanges (PBXs) taking up space in your office, companies are moving everything to the cloud; with Unified Communications, the way forward.

Telephony and communications are fast becoming digital.
SIP trunking - Session Initiation Protocol - is another cloud-based solution that businesses are embracing, replacing the need for hardware PBX systems. Instead, VoIP services connect phones to networks, improving voice quality, whilst making it easier for companies to communicate through video, web conferencing and screen sharing.

ISDN can’t handle modern communication needs. Internet-based communications are already overtaking analogue solutions. Now's the time to make sure your business is equipped for a digital future.
