Businesses have just over 5 years left to look for an alternative solution to their telephony and internet needs. Fortunately there are a range of affordable solutions available.
We look at the old technology that will be switched off, the reasons for the switch, what alternatives are available and how they can benefit your business. Read more.
What is a PSTN line?
“The public switched telephone network (PSTN) is the aggregate of the world's circuit-switched telephone networks that are operated by national, regional, or local telephony operators, providing infrastructure and services for public telecommunication” - Source
Analogue voice data is sent over a circuit-switched phone line made up of copper wires which is owned and operated by your phone provider.
ISDN is a telephone network based infrastructure, which enables the transmission of both voice and data simultaneously. There are many advantages of ISDN such as − As the services are digital, there is less chance for errors. The connection is faster.
What is an ISDN line?
- . Network Termination 2 (NT2) is typically the telco's device (it's very rare to see this at the customers site) that is used to terminate from the customers NT1 device before traffic hits the ISDN network. This operates at Layer 2 & 3 of the OSI Model and is an intelligent device performing the switching.
“Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network” - Source
Put simply your standard telephone line is used to send voice and data over the same line. Therefore you can make phone calls on a home telephone and plug your broadband router in to access the internet using the same port.
Why is BT switching to IP?
BT introduced ISDN lines nationwide in 1986, and since then connectivity has advanced greatly. The investment and nationwide roll out ofsuperfast internet and Ethernet products provides a viable alternative.
In fact, BT have not installed any new ISDN lines in central London since 2014 which goes to show that many businesses have already moved on. But switching over 3 million active ISDN users is no small task - hence why they have given businesses so much notice.
What are the alternatives to ISDN lines?
The recent investment in the UK communications network has made the new fibre infrastructure widely available and affordable to small businesses. This means IP based solutions such as VoIP and SIP are the top alternatives for businesses.
What is SIP?
SIP (Session initiation protocol) provides you with a phone line which is carried over your fibre internet connection removing the need for an ISDN phone line. SIP lines used to have reliability problems due to inadequate underlying broadband connections. These issues have now been fixed due to connectivity improvements and Service Level Agreements now offered by providers.
What is VoIP?
VoIP is a cloud based telephony solution which moves your whole phone system online, so all your calls are sent over your internet connection. This digital cloud based phone system offers a wide range of additional features such as call recording, receiving voicemails via email, call queuing and unified communications – being able to access the system on multiple devices such as a mobile, tablet and desktop.
Top 5 Benefits of SIP and VoIP
- Huge savings – Up to a 78% reduction in costs compared to ISDN due to cheaper calls and no more expensive line rental.
- Greater flexibility – Move anywhere in the UK and simply plug back into the network with no need to change numbers.
- Faster installation – No more waiting for an engineer to install physical lines means you get connected faster.
- Higher resiliency – Multiple fibre lines can be installed providing an automatic backup and failover so you’re always connected.
- Advanced features – Increased control, integration and analytics offers a huge range of new and advanced features.

Stands for 'Integrated Services Digital Network.' ISDN is a telecommunications technology that enables the transmission of digital data over standard phone lines. It can be used for voice calls as well as data transfers.
The first ISDN standard was defined in 1988 by the CCITT organziation, which is now the ITU-T (International Telegraph and Telephone Consultative Committee). However, it wasn't until the 1990s that the service became widely used. Since the introduction of ISDN, several variants have been standardized, including the following:
Isdn Network & Wireless Cards Drivers
- Basic Rate Interface (BRI) - supports two 64 kbps bearer channels (or B channels) for a data transfer rate of 128 kbps.
- Primary Rate Interface (PRI) - supports 30 B channels and two additional channels in a single E1 connection, providing a data transfer rate of 2,048 kbps.
- Always on Dynamic ISDN (AODI) - an consistent ISDN connection that uses the X.25 protocol and supports speeds up to 2 Mbps.
Isdn Network & Wireless Cards Drivers
ISDN was a common high-end Internet service in the 1990s and early 2000s and was offered by many ISPs as faster alternative to dial-up Internet access. Many businesses and organizations used ISDN service for both Internet access and network connections between locations. In the mid-2000s, DSL and cable serviced began to replace ISDN connections because of their faster speed and lower cost. Today, ISDN is still used in some network connections, but it is rarely used for Internet access.
