"Multi-roam SIMs as backup plan to protect your lift business"

In the UK, fibre optics will replace copper cable by January 2027. Lift operators should take care of upgrading their emergency call systems as soon as possible. Chaim Grunfeld gives tips for the switch from analogue to digital.

The era of the copper cable will end in the United Kingdom on 31 January 2027 at the latest. Instead, the expansion of the fibre optic network for high-speed broadband services is being driven forward. The fact that the analogue telephone line is being cut is likely to pose a huge challenge for lift operators.

"Many lift alarm systems use analogue telephone lines and need a dial tone and dual-tone multi frequency (DTMF) signalling to work. A significant number of lift alarm systems also make use of the DC voltage available on the line," explains Micky Grover White, Technical Manager at British Lift Association LEIA, in an article published in the LIFTjournal.

To ensure that the emergency call system continues to work after 31 January 2027, lift operators will have to look for alternatives. Chaim Grunfeld, founder of Sims4Lifts - a British company that specialises in communication solutions for lifts - suggests switching to modern mobile communications technology. In this interview, he explains the background.

What are the main challenges that lift operators face when upgrading to digital comms?
Grunfeld: Upgrading from analogue to digital is a real game changer, but it comes with its fair share of bumps. The first hurdle is compatibility. Many older lifts were built with analogue technology, so transitioning them to digital can be difficult. Oftentimes, lift operators will need to make significant modifications, introducing the right mobile communications technology – a potentially costly and time-consuming overhaul when conducted at scale. 

Then, there’s the issue of network reliability. Unlike tried-and-true analogue networks, digital systems rely on mobile connections, which, as we know, can be unpredictable. This variability can affect the performance of emergency communication systems, which are essential for safety, not to mention compliance. So, choosing the wrong network is like having a lifeline that might not always be there when it matters the most.

What can lift operators do to address this?
Grunfeld: Tackling compatibility is all about careful planning. Start by getting a clear overview of your current lift systems, a bit like mapping the terrain before setting out. This helps you to understand what needs upgrading and by when, helping you to tackle things more effectively.

Investing in a retrofit kit designed for your specific lift model can iron out the kinks, ensuring that any new digital mobile communications components mesh seamlessly with existing systems. You’ll want to partner with suppliers that offer comprehensive support, ensuring that everything runs seamlessly without operational hiccoughs.

What role do multi-roam SIMs play in this transition? Why are they important?
Grunfeld: Operators will often buy their SIMs as part of a package with a gateway. The problem with this is that the SIMs included aren’t always the most reliable for lifts. Sometimes coming with international numbers, they’re often limited to a single network, with the thickness of walls and number of floors in multi-tenant spaces, especially in busy areas, increasing the chances that the emergency phone call won’t work due to poor signal or network connection.

Multi-roam SIMs are essentially the hero answer to this – a bit like a backup plan that will protect your lift business. Put simply, these SIMs have the ability to connect to, not just one, but multiple mobile networks – always opting for the strongest available connection at any given moment. This is crucial for maintaining reliable emergency communication and safeguarding your lift company’s reputation.

Rather than being tethered to one network, like 02, Vodafone or EE, multi-roam SIMs allow lifts to switch, ensuring that your lift’s communication systems remain solid, even in the face of network fluctuations.

And what can lift operators do to ensure reliable and effective digital systems over time?
Grunfeld: There are a number of things that operators can do. First, it’s imperative to ensure you’re keeping your digital systems in top shape. This means investing in quality, especially with regard multi-roam SIMs. Quality gear and quality mobile connections facilitated by a company that has your back is much less likely to fail – plus it comes with much better support.

Then, there’s the matter of routine inspection. Conduct regular check-ups to catch any issues before they become major problems and, if you notice coverage problems, work with your suppliers.

Training staff is also important, as well-trained personnel can do much more to prevent common issues. Likewise, teaching building clients about what you are doing can be a huge help, as customers are much more likely to embrace contingency plans – like multi-roam SIMs, when they understand them as the vital safety net that they are.

Finally, do you have any professional tips for managing the transition smoothly?
Grunfeld: Absolutely. A smooth transition is all about preparation and strategy. Plan ahead rather than leaving things until the last minute, ensuring that your upgrades are done well before analogue networks are switched off. It’s like preparing for a marathon, where training ahead of time pays off. Openreach has pushed back the date of the big switch off to give people more time to prepare, but it is highly unlikely that it will do so again.

Consulting with digital communication experts, like the team at Sims4Lifts and mobile communications providers is also a must – particularly early on, as it helps to avoid common pitfalls. Pilot tests with a small number of lifts can also be a great idea before rolling out your chosen digital solutions across the board.

Whatever your plan, always keep all relevant stakeholders informed and maintain detailed records of your upgrade process, to ensure everyone is on the same page and to establish a clear roadmap to guide you through future transitions in your upgrade journey.
