What’s happening?
In 2015 BT announced the PSTN and ISDN switch off - moving the UK to a full IP network by 2025.
Although the timeframe given seemed to be a way off at the time, it’s been a phased approach with many
exchanges already operating as IP only and many services being moved to ‘stop sell’ status, meaning that they are no longer available for new provision.
Businesses and consumers who still utilise traditional analogue and digital services will need to move to
IP solutions when their local exchange is enabled. Moving to data only connectivity means that the voice
aspect of customers’ communications needs to be considered and applied separately, as there are no ‘voice only’ substitutes.
What connection types are being phased out?
Analogue and digital voice and copper based broadband services - PSTN, ISDN 2, ISDN 30, LLU, SMPF, SLU SMPF, NBLS and Classic services.
What other services are affected?
Not only the physical connections need to be considered, but what are they currently being used for apart from voice calls and providing broadband? The following are examples of consumer and business critical services that will also be affected:
Fax lines
Fire and security alarms
CCTV
Redcare
Payphones
Lift emergency lines
EPOS systems
Door entry
Panic alarms
Bandwidth modifications
Additions of lines and channels to existing installations e.g. adding/removing ISDN channels
