Tunnels de Cointe in Liège : a new high-security emergency telephone system, developed and installed by Tein Technology

Experiencing car trouble in one of the 2 Tunnels making the link between the highways E40 & E25 in Liege? Then it’s good to know you can always – and we mean, always – rely on the emergency telephones throughout the tunnel. These telephones will immediately connect you to the control room (Tilleuls Center), where experienced operators will find a solution to your problem.

Replacing a conventional telephone system with a redundant VOIP system

The telephones are directly connected to the main control room, where a smart system of cameras and other tunnel management technology are used to guarantee safety inside the tunnels. This hub detects any problem in the tunnel and acts quickly to resolve it.

Tein Technology developed specific and specialized software for this project, as the network needs to interact with other communication and security systems, such as emergency services. The current telephones were kept in place, but a state-of-the-art VOIP telephone system was integrated, running on redundant servers located on two different sites for guaranteed uptime.

We fitted the control room with the necessary recording systems, so that every call can be used for analysis purposes in the future.
