Kathrein ESM 40 Modem socket for interactive CATV / HFC networks (TV / FM / modem connection) (optional)
I put some KATHREIN ESM 40, 41 and 42 here in my apartment, and am therefore fully satisfied. The special feature is that I have built up my coax cable for TV and radio a very fast Ethernet network, modern powerline adapters to the HomePlug AV2 stand
