The WLR Withdrawal affects more than just ISDN Phone Lines
The ISDN Switch off should really be called the PSTN Switch off or maybe Wholesale Line Rental (WLR) Withdrawal.
As a refresh for what has happened so far, BT Group announced in 2018 plans to close its traditional telephone network (the PSTN) and migrate all customers to new digital, internet based (all-IP) services by December 2025. The PSTN supports a number of Openreach wholesale products including: Wholesale Line Rental (WLR3), Integrated Services Digital Network (ISDN 2 and ISDN 30), When the PSTN is switched off these products will no longer be available.
That means in addition to the ISDN services that all analogue lines will also be switched off. What’s interesting is that all the network providers are predicting that at the current rate of change all companies will have moved away from the PSTN by 2023.
Have you migrated away from ISDN yet?
Most businesses in the UK have already migrated their communications to IP based solutions such as SIP Trunking or Cloud based VOIP Telephony or often called a Hosted Phone System to take advantage of the significant benefits of an improved service at a lower cost. However there are still a significant number of businesses that still need to make the switch to IP.
Analogue Lines will also be switched off
What most businesses are unaware of is that the WLR withdrawal or the PSTN Switch Off means that existing analogue lines will no longer be available. This gives organisations a different challenge to ensure all the existing services provided over copper analogue lines, are migrated to compatible IP or 4G networks.
There are many services provided over analogue lines including:
1.Broadband (ADSL and FTTC)
2.Voice (plain old telephone & small business or office phone systems)
5.Emergency systems (panic buttons)
6.PDQ Machines (credit & debit card payments)
