It is a critical system that meets strict requirements of high reliability and low maintenance.

As the emergency telephones are a critical part of the tunnel infrastructure, the update was performed alongside the live system without interruption.

New features were added that incorporated the most recent developments in electronics and communications, which brought the system up to date and functioning more efficiently while maintaining the reliability it had become known for.

These updates also provided easier to use interfaces in the control room, allowing operators to be more effective when assisting motorists during an emergency, and to perform the testing of the system more efficiently.
