@langoc Hi,
I didn't find a product named ATN9205.
In my opinion, if you are searching for a router which could provide 100G bandwidth, this router should be a core router. For a core router, such as NE5000 or NE40, they provides the powerful forwarding capacity. In the final analysis, 5G service is the data service, so it could be carried on the core routers.
Anyway, this is my thought, if you are looking forward for the more professional information, you are kindly advised to contact with the pre sale engineers.
