Over the last few years Openreach, the UK’s telephone line infrastructure provider, has been rolling out fibre telephone lines as part of their ‘fibre first’ programme. The legacy, copper telephone line-based, public switch telephone network (PSTN) has served the UK well for many years but is no longer able to keep pace with our ever-increasing demand for data over voice services. The UK government estimates that the deployment of fibre phone lines will provide a £59bn boost to productivity and bring a million people back into the workforce by the end of 2025.

However, telephone lines service several applications other than internet connections and telephone handsets, notably: lift alarms.

Lifts are an essential part of the operation of any multi-storey building. Both in terms of how people and goods flow through your building and ensuring your building is accessible to everyone regardless of their abilities. Every day, thousands of passengers travel in lifts without giving it a second thought. How many lift journeys have you taken today or this week?
