This is a network switch.. what does a specific provider has to do with it? Was that something that Swisscom told you??

Correction, the switch does work when connected to the Swisscom internet-box - however, the Swisscom TV-Box is not compatible. After a few seconds, regardless of the channel, the program freezes and won't start again. As the SG-105 is a plug-and-play device without an IP-address (not manageable), there are no settings that can be changed.

Living in Switzerland, buying from a Swiss company, it would be helpful to know the compatibility of a product, especially for IT amateurs as myself. Did quite some research, apparently not enough - learned my lesson!
