We are making our networks faster and more efficient. To do this, we are deactivating all analog public switched telephone network (PSTN) platforms that we no longer need and switching our entire telephone network to IP-based lines. By the end of 2019, around 99 percent of lines had already been switched to IP technology.
Irrespective of the expansion and renewal of our infrastructure, we aim to operate our networks in the most stable and failure-free manner possible. Major events such as festivals and summits place the network under particular strain. We make sure, however, that voice calls and data are still transmitted in the quality our customers have come to expect by temporarily setting up extra mobile masts or laying fiber-optic cables. In the event of natural disasters such as floods, our Disaster Recovery Management team ensures those affected can quickly start communicating again.
