ISDN & PSTN switch off

What is the ISDN & PSTN switch off?

In 2015, Openreach announced that they will be switching off the PSTN and ISDN network by 2025, marking the biggest change in the telecoms industry for over 30 years, but what does this mean for you?

• PSTN (Analogue line). This is the line that a classic broadband product will use to run into your building. Carrying ADSL and FTTC.
• ISDN. This product sits on the PSTN network and provides dual lines for businesses that have 2 or more users on their lines and telephone systems.

So if you have either of the above products, which most will, this seriously effects you and we would recommend you read on to know what’s required and when, and please use us for advice.

We’re here to help you prepare for the approaching deadline.

We have all the knowledge, tools, products and pricing to make sure you’re ready, set and  future proofed way ahead of the deadline.

And within an affordable, top quality and well managed package.

The Public Switch Telephone Network (PSTN)

is aging and will reach the end of life in December 2025. The PSTN network supports a number of Openreach products which Communication Providers (CPs) purchase at regulated pricing and often sell to businesses and consumers, wrapped up in their own line rental, broadband and call package deal. These include: Wholesale Line Rental (WLR) and Integrated Services Digital Network (ISDN).

PSTN will also be used to support a business or residential broadband connection, which will be on either ADSL or FTTC (fibre to the cabinet).

You may need to wait some time to replace PSTN, due to the availability of the new products on the Openreach network, but with us we will always keep you up to date on what’s available and when.

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 digitalised circuits of the public switched telephone network.

A traditional PBX Telephone system will be on the ISDN infrastructure, so these systems will need replacing with an upgraded product.

So if this affects you, please take a look at your options, as you will need to upgrade.

Upgrading These Products

PSTN for voice will be replaced by products called SOTAP & SOGEA, which are products that are line & broadband inclusive in one package, rather than needing the 2 combined.

And contrary to popular belief you do not ‘have’ to upgrade from ISDN to a Cloud-Hosted (VoIP) service. There are options… certainly with us.

It is true however, that any new system will use broadband connectivity to handle the voice calls.

Unlike most Telecommunications service providers, CV&D have options for your  upgrades.
