Hello,
"operator", that means who is responsible for the platform (sign), is only the ASEAG. Neither there is a TEC sign nor TEC would fix it in case of damage (or update the timetable...).
Regarding "network": The bus line 14 belongs to both networks, but the platform does not. Please see https://wiki.openstreetmap.org/wiki/Key:ref:IFOPT. That ID is given by the AVV.
Regards
