The BT PSTN & ISDN Switch Off
The WLR Withdrawal process is accelerating; are you ready?
Upgrading the Access Network
BT & Openreach’s decision to switch off the Public Switched Telephone Network (PSTN) & Integrated Services Digital Network (ISDN) is mainly due to both technologies becoming out of date and expensive to operate and maintain.
Openreach plans to invest more into modern-day technology and hence focusing instead on deploying fibre infrastructure and future-proofing their network across the UK.
Any individual or organisation still using these traditional voice services will need to have moved to newer SIP and IP voice solutions in the near future. If not, then they simply won’t be able to use their phones or any service that is being delivered using a PSTN
No more dial tone; alternatives?
SIP and VoIP
The terms SIP and VoIP refer to telephony based services delivered using Internet Protocol (IP) signalling.
What is SIP?
SIP services are generally used to connect lines to a telephone system and these are a direct replacement for the ISDN technology.
It is designed to support real-time multimedia sessions between groups of participants. In addition to telephone calls, SIP can also be used to set up video and audio multicast meetings, or instant messaging conferences.
What is VoIP?
This is a general term used to describe routing voice calls over an IP network.
The term is closely associated with hosted telephones, where a telephone system installed at a customer’s premises is replaced with a central system shared between many different locations.
Flexible VOIP telephony systems can be delivered fully hosted in the Cloud, on-premise or a combination of both (hybrid).
They are easy to manage and incorporate a number of features including instant chat, video conferencing, screen sharing and phone calls through mobile apps.

The Public Switch Telephone Network, was introduced in the 1800 and is a circuit-switched analogue telephone system that enables the transmission of voice and data (broadband) through a network of copper wires. This system is also referred to as landlines, Plain Old Telephone Service (POTS) or fixed-line.
PSTN is used by residential and business customers.
Integrated Services Digital Network (ISDN) allows for simultaneous digital transmission of voice, video and data services over the traditional PSTN copper network. This is mainly used by businesses to support multiple users to make & receive calls at the same time, over the same link, using different channels to keep the traffic separate.
ISDN comes in a number of options:
Mainly used by small businesses. With ISDN2e you can connect up to 60 channels. Channels are sold in pairs and can be bonded to increase bandwidth for things like video conferencing.
This is designed for businesses that need high-quality video conferencing, consistent transfer of large data files, or that operate call centres.
Each connection provides 8-30 independent 64k channels. You can combine these for bandwidth intensive applications such as high-quality video conferencing or large data file transfers.
This is the same as ISDN30 but with some additional features like Customer controlled Call Forwarding and Call Deflection.
Wholesale Line Rental (WLR) allows alternative suppliers to rent access lines on wholesale terms from Openreach, and resell the lines to customers, providing a single bill that covers both line rental and telephone calls.

As technology evolves, it introduces new ways to deliver greater agility, efficiency and security to a wealth of business processes. As enterprise infrastructure becomes increasingly borderless and hybrid working becomes the new normal, computing resources are being pushed to the network edge, empowering a work from anywhere environment.
Resilience is a core element of business operations. It is a wide-ranging principle that includes business continuity and disaster recovery But both of these are dependent upon a resilient IT and communications infrastructure. It is an organization’s ability to carry on business as usual in the event of an unexpected, potentially service-impacting incident.
Change is inevitable, but the speed of change seems to have been accelerating in recent years. This can make long-term planning difficult for many organisations so, when the long term is unpredictable, the best option is to make sure your business is agile enough to cope with change.
The impact of cybersecurity incidents, such as data breaches, can felt throughout the organisation and beyond. Vulnerabilities within any business can impact stakeholders both up and down the supply chain, with the penalties ranging from regulatory fines to a loss of revenue, significant business interruption or damage to brand and customer loyalty.
