Stay ahead of the analogue switch-off with Otis ONE

The telecommunications industry is transitioning from the old copper cabling technology known as the Public Switch Telephone Network (PSTN) to modern fibre optic cables. This transition means that all future telephone calls over 'fixed lines' will be made using Voice Over Internet Protocol (VoIP).

The transition will be gradual, with a planned completion date of January 2027, at which point the old network will be 'decommissioned'. As many lifts currently use the PSTN to connect their alarm systems, this change could affect your building.

The Otis ONE Plus and Pro packages offer innovative solutions with embedded 4G or digital voice services for emergency communications. These solutions ensure safe and efficient building performance while seamlessly adapting to the industry's transition from copper to digital communications.

As your end-to-end service partner, we are here to advise on any questions you may have regarding this transition and what steps you need to take to remain compliant and ensure the safety of your passengers.

Key questions you may have about the analogue switch-off

What are the main standards and regulations for lift emergency communication systems in the UK?

What are the main standards and regulations for lift emergency communication systems in the UK?

In the United Kingdom (UK), lift emergency communication systems are primarily governed by several standards and regulations to ensure safety and reliability since 1988. EN81-1 and EN81-2 provide clear guidance on the installation of a communication line to allow a trapped passenger to call for help. Today, the main standards and regulations in force are as follows:

Today, the main standards and regulations in force are as follows:

• BS EN 81-28: This standard specifies requirements for remote alarm systems on passenger and goods passenger lifts. It includes features like two-way communication available 24/7 between the lift and a rescue service, alerts for network failures, and backup power for emergency devices.

• Lifting Operations and Lifting Equipment Regulations (LOLER) 1998: LOLER stipulates that lift owners must ensure that passengers can summon assistance if trapped. This is a legal requirement under the Health and Safety at Work Act.

• Transition to Internet Protocol (IP) Technology: The UK is transitioning away from traditional Public Switch Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) lines, opting for Internet Protocol (IP) systems such as Voice over Internet Protocol (VoIP). By January 2027, lift owners must ensure that their emergency communication systems are compatible with this new technology.
What are the obligations of lift owners and building managers in the UK regarding lift emergency communications?

What are the obligations of lift owners and building managers in the UK regarding lift emergency communications?

As a Lift Owner or Building Manager in the UK, you have several key obligations regarding lift emergency communications to ensure the safety and compliance of your building:

1. Two-way communication: All lifts must have a two-way emergency communication system to allow trapped passengers to call for help. This is a requirement under LOLER.

2. Compliance with Safety Standards: Ensure that the communication system complies with BS EN 81-28, which sets out requirements for alarm systems in lifts, including back-up power, network failure alarms and regular testing.

3. Regular maintenance and testing: The emergency communication system should be regularly inspected and tested to ensure it is working properly. Any faults should be rectified immediately.

4. Transition to IP technology: With traditional PSTN and ISDN lines being phased out in the UK, you need to ensure that your lift's communication system is compatible with Internet Protocol technology, such as VoIP (Voice over Internet Protocol).

5. Risk assessments: For older lifts (installed before 1998), carry out a risk assessment to determine whether upgrades are required to meet current safety standards

6. Emergency Response Protocols: Establish clear protocols for responding to list emergencies, including ensuring that emergency calls are answered promptly and that assistance is dispatched quickly.

If upgrades are not implemented before the switch-off, building owners risk potential fines or legal liability if an emergency occurs and no communication is available.

You may connect with Otis to assess your situation. We can help whether or not you have a maintenance contract with us.
What are PSTN and ISDN lines?

What are PSTN and ISDN lines?

The Public Switch Telephone Network (PSTN) is the traditional copper wire phone lines that have been in use since the introduction of the telephone. The technology dates back to the 19th century, is very expensive to maintain and has limitations in terms of signal capacity and the amount of data that can be sent.

Integrated Services Digital Network (ISDN) is a technology from the 1980s, but even this option relies on fixed and hardwire phone line connections to transmit voice and data signals.
What is the “analogue switch off” about?

What is the “analogue switch off” about?

Openreach, a subsidiary of BT, has announced that it will stop supporting ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) lines by January 2027, with a complete switch to Internet Protocol (IP) technology, primarily Voice over Internet Protocol (VoIP).

This transition to digital means that the UK's traditional copper telephone network will be phased out, requiring lift and escalator operators to upgrade their emergency call systems, as many currently rely on analogue lines.
How will the ‘analogue switch off’ affect your lift?

How will the ‘analogue switch off’ affect your lift?

Many lifts still use autodialer systems that automatically dials a phone number. A significant portion of autodialer systems still use PSTN (Public Switched Telephone Network) lines.

These devices will stop working when the PSTN lines are switched off as part of the analogue switch off. This means a trapped passenger cannot make a call in the event of an emergency, such as an entrapment. Your lift(s) could also be deemed noncompliant during a LOLER (Lifting Operations and Lifting Equipment Regulations) inspection.

This is why it is critical to upgrade your equipment to support the new VoIP (Voice over Internet Protocol) technology with solutions such as our Otis ONE Plus digital platform.
How do I know if I will be affected?

How do I know if I will be affected?

The Lift and Escalator Industry Association (LEIA) recommends that you seek the advice of the lift service provider, who can check your emergency telephone connection and advise you if you are likely to require a change to your hardware.

You may connect with Otis to assess your situation. We can help whether or not you have a maintenance contract with us.
What type of phone lines will be required as part of the analogue switch off?

What type of phone lines will be required as part of the analogue switch off?

The phone lines will be migrated to Internet Protocol, (IP) technology. There are two types of IP technology:

1. Voice Over Internet Protocol (VoIP) – This receives and makes voice phone calls over the Internet. This is also the most common type of IP.

2. Session Initiation Protocol, (SIP) – As opposed to just being able to send voice data over the internet, SIP has the capability to receive and send multimedia data. This allows for video calling.
Who is responsible for the upgrading the technology to ensure a working emergency communication system in the lift?

Who is responsible for the upgrading the technology to ensure a working emergency communication system in the lift?

The lift owner is responsible for ensuring that a lift complies with safety standards and regulations, including the lift's emergency communication system. The lift owner may be the building owner, the building manager or the duty holder for the lift.
What are the key dates I need to know with regard to the ‘analogue line switch off’?

What are the key dates I need to know with regard to the ‘analogue line switch off’?

The official date that BT are giving is January 31st 2027.

It should be noted however that BT are advising all business customers to upgrade to the latest IP technology by the end of December 2025 to prepare well in advance of the January 2027 deadline and because some areas will make the switchover sooner.
What solution can Otis offer to upgrade my landline?

What solution can Otis offer to upgrade my landline?

Otis offers a number of options that can solve any connectivity issues you may have when analogue lines are switched off, particularly our Otis ONE Plus, IoT solutions.

In fact, one of the key benefits of our Otis ONE Plus solutions is that they incorporate a Global Service Mobile, (GSM), which provides connectivity for your lift and eliminates the need for a landline. With landlines due to be ‘switched off’ in January 2027, these solutions can ensure that your lift’s autodialer, which ensures effective communication in an emergency situation, remains functional and that the building owner or manager remains compliant.

Our Otis ONE Plus solution also offers much more than a simple voice service. It gives you access to real-time information, less hassle because you have one supplier to manage instead of two, the potential elimination of charges when your lift is running and we can see it remotely - we avoid sending an engineer at your expense.

Here is what our customers and mechanics have to say

“I stay ahead of what’s happening in the properties I manage. I receive real-time notifications by text as soon as an event occurs, which is perfect for me as I am always on the go.”

As a hotel manager, I always need to find ways to improve the way I welcome my guests. I subscribed to the eView™ in-car screen solution to offer my guests the information they need with minimal disruption during the installation.

We are impressed by this solution from Otis. We wanted to access real-time operation data to track elevator service as part of our value proposition to tenants, and to rethink their business model.

We subscribed to Otis API digital service to integrate elevator availability, maintenance insights, and traffic per floor data in our own Building Management System from the Otis Developer Portal.

As Chief Engineer in a large hospital, I consider elevators to be mission critical for patients. Complex shutdowns are solved more quickly, doctors operating schedules are not disrupted and visiting families can get to their sibling’s room directly.
