Switching lift phone systems to IP

All IP know how

Switching lift phone systems

Lift phones that transmit emergency calls over the traditional fixed network are affected by the switch to IP. Swisscom plans to replace the traditional fixed network connections with IP-compatible telephone lines by the end of 2017. The old telephony infrastructure will be gradually decommissioned from 2018. Customers who have not yet switched to an IP product by then will be helped to do so by Swisscom. We advise lift manufacturers on mobile telephony products or alternatives specially designed for the lift sector.







Frequently asked questions


Which lift phones are affected?

Only lift phones that currently transfer emergency calls using the conventional fixed network (analogue or ISDN) are affected. Many systems are not affected because they only transmit alarms over the mobile network.

As a lift manufacturer, what must I do?

Swisscom CMP Lite uses the innovative technology of the Connectivity Management Platform for a product specially designed for the lift sector.



As an owner, what must I do?

Contact your maintenance agreement provider or the lift manufacturer as soon as possible. They will take the necessary steps to ensure the reliable operation of your lift phone system.

What will the switch cost?

Some lift manufacturers include the modification costs as an additional package in their maintenance agreement. In this case, the owner will not pay the costs associated with the switch. Other manufacturers charge a one-off fee for switching the lift phone system over to the mobile network. In general, the customer pays less because there is no monthly fee for the fixed-network infrastructure and mobile solutions tend to be cheaper.



Why is Swisscom moving to mobile communications?

Mobile solutions are a good option today. For fixed IP telephony, no optimised router with integrated battery is currently available and the function of the IP connection is not always guaranteed in the event of a power failure. However, Swisscom is checking alternatives with a fixed network connection.




Mobile communication solutions for lift telephone systems


M2M agreements for lift manufacturers

M2M (machine-to-machine) agreements can be economically viable from around 50 SIM cards, with individual contract terms and different network connection options and security features.



Machine-to-Machine (M2M)

With M2M, machines are able to communicate with each other and react in real time. Applications for lifts include alarm systems, remote monitoring, remote control and remote maintenance. Lift manufacturers are now able to manage and control traffic and costs (data, SMS and emergency voice calls).



Mobile solutions for private owners and smaller manufacturers

For smaller lift manufacturers or private lift system owners, it is worth considering a NATEL® company subscription.



Exceptionally high network availability

The latest analyses involving several major lift manufacturers indicate almost universal mobile (GSM/UMTS) coverage (approximately 99,9%). 4G/LTE coverage is currently 97% and is being rolled out even further. Depending on the building infrastructure or location installation of the SIM card casing, an external antenna can be used to improve reception. For the one in a thousand lift locations which has no mobile phone network, an individual solution will be sought with the customer.



Power supply

The Swisscom mobile phone network is safeguarded by one hour of battery power. Since 1999, lift manufacturers have to provide an uninterruptible power supply (USV, battery) for every new lift system. If a rechargeable substitute power supply is used, there has to be a way to automatically advise the emergency services as soon as the capacity is less than required to operate the emergency system for one hour.


Mobile coverage during a power failure


If there is a power failure, Swisscom ensures its mobile phone network can continue to function by battery power for an hour. Check the availability of the mobile phone network during a power failure at your location.
