Why is BT Switching off the ISDN Network?

What does that mean for your business and how can our Experienced team from b4b help you

In 2015 BT announced that they would stop taking new orders for ISDN in 2020. They also stated that they would deactivate the entire ISDN network by the year 2025.

What does that mean for your business and how can b4b help you out.

Why do Businesses use ISDN2 and ISDN30?

ISDN (Integrated Service Digital Network) is a telephone network system that allows voice and data to be delivered over a digital line at the same time.

Initially released in 1986, it allowed businesses to have digital lines instead of standard analogue lines.

Digital lines are higher quality in terms of voice, but the main advantage was the ability to transfer data.

For a business this meant they could do basic video conferencing and give them fast Internet access at that time.

Why do Businesses no longer need ISDN?

Technology in the telecommunications industry has moved on a great deal in the last 5 years. Fast Internet access is now provided through connections such as fibre broadband, DSL or leased lines. That makes the use of ISDN redundant and as such is now considered to be a legacy technology.

It is now being replaced with a range of VOIP (Voice over Internet Protocol) solutions. Unlike traditional analogue and ISDN lines, VOIP does not require the use of copper cables in the ground.

Around 50% of Northern Ireland businesses have already made the move to some form of VoIP such as a Hosted PBX or SIP Channels.

Why Make the Move to SIP/VOIP?

VOIP is a modern progressive technology with several important benefits and advantages over the older traditional lines: 

  • Speed of Setup – It is much faster to provision and setup a new line
  • Line Rental Costs – As your business will need fewer lines, your business line rental will reduce
  • Scale and Flexibility – When you combine for example a cloud based system with SIP lines it is easy to transfer calls between offices in different locations, and to allow employees to work from anywhere

SIP from b4b

ISDN is being replaced with SIP Channels or SIP trunks. SIP stands for Session Initiation Protocol. In the world of communications there are two parts involved when making a telephone call. There is the initial setup of the call, and then the actual data transfer, which in this case is the voice element of the call.

SIP can also be used to set up video, multicast meetings and instant messaging conferences.
For most businesses in Northern Ireland, each channel of ISDN would simply be replaced with a SIP channel, which operates through a Broadband connection. SIP is a high-quality offer and also much cheaper than ISDN line rental.
