Copper Wire Telecoms

Debate between Helen Morgan and Chris Bryant

Wednesday 13th December 2023 Westminster Hall

[Sir Chris Bryant]

I will come on to that point about the difference between inside and outside, which certainly applies to homes in the Rhondda. The point was also made by the right hon. Member for Suffolk Coastal. I am not sure whether the hon. Member for Glasgow North West (Carol Monaghan) was saying that the signal on the parliamentary estate was temperamental or that the MPs were—maybe it is a bit of both. The hon. Lady made other good points about the potential for criminality. This is not a point that I have heard elsewhere. The Minister may want to refer to it later.

One of the biggest problems with this debate is that the vast majority of people in this country would have absolutely no idea what we are talking about. In fact, I would guess that of the 650 MPs, barely 10% would know what we are talking about. That is a potential problem, because if the public does not know what we are talking about, there is a danger for other people to exploit that lack of understanding and knowledge. Several Members have referred to the fact that this is primarily an industry-led, rather than Government-led, project. They are quite right, but the Government have a significant responsibility in this area. Towards the end of my speech, I will come on to a few things that I think the Government may want to look at.

There are real, legitimate concerns. PSTN—if 650 MPs were asked to say what that acronym stood for, my guess is that we would be lucky if 10 of them knew the answer—stands for public switched telephone network, and I only know that because I am reading it out.

The complete lack of public understanding of the issue is significant. The industry is extremely diverse, with roughly 650 providers in England alone, let alone the rest of the UK. As has already been referred to, BT has decided to delay its digital voice roll-out, and instead of a national roll-out by the end of December 2025 there will be a region-by-region roll-out, which adds a degree of complexity to any kind of national understanding of this issue. Indeed, I would argue that there is even less clarity about what is happening now than there was back in 2022.

As has already been said, some devices rely on PSTN. Security alarms are one. I would guess that quite a few MPs have security alarms. I wonder how many of those alarms are reliant on PSTN; I have no idea.

[Helen Morgan]

I will just highlight that point by drawing on personal experience. New security alarms do not rely on the copper network, for that reason, but they are reliant on a mobile signal, so if there is no mobile signal, they will not work.

[Sir Chris Bryant]

Indeed. That is a point I will come on to again later.

The hon. Lady and the right hon. Member for Orkney and Shetland referred to telecare devices, with 1.7 million people in the UK relying on them. I am not quite sure what percentage of those devices are still on PSTN, but I would guess that it is a pretty high. One of the problems that plagues the debates on this issue is that we do not have reliable data and statistics, so the Government should try to ensure that we do.

A significant number of traffic lights rely on PSTN. There was a time in Russia when people in the Russian Federation thought that a red light meant that they should drive very fast, which was a bit of a problem. Then there was a problem because all the traffic lights in Russia went off at 10 o’clock at night, which led to other problems. I do not know whether the British Government know how many British traffic lights rely on PSTN, but maybe the Minister will be able to enlighten us later.

Then there is closed circuit television, or CCTV. There is a wide variety of different systems of CCTV up and down the country. Many of those systems will now have transitioned, but some have not.

I feel very old-fashioned in saying this, but fax machines are another thing. I saw a fax machine a couple of weeks ago in a hospital, and it is extraordinary that some of our public institutions still rely on fax machines because other forms of data interoperability simply do not exist.
