Recessed network cabinets are wall-mounted enclosures designed to be installed flush within walls, offering concealed housing for networking hardware such as patch panels, routers, switches, power supplies, and fiber termination boxes. Not sure what outside box your ISP would be installing in there? I would expect just a modem? Either way, I would want the modem outside of the cabinet just because modems run hot. If your using non-managed switches, my preference would be inside the cabinet as they produce less heat than POE.
