Fellow List Peoples, I have a product that takes in various signals and connects these to output ports, something like an Ethernet switch (but does not meet the definitions of the regulation for that). The product was not designed to monitor "traffic" on any of the ports so it cannot know when the port/path is not being used.
The product is configured and controlled only by an external controller. When a path is not being used, the external controller sets the output ports to null. The controller is in constant communication with the product, much like a ping on the network. The product will go automatically into standby on power up if no controller is connected. The product is smart enough to know when all ports are set null and will go into standby when it senses that. The product will also go into standby if it loses communication with the controller. But it cannot know if "traffic" is passing. The key question here is, can we use the external controller to determine when the product should go into standby? Is that a fair means to address the "...must automatically go into a mode..." requirement? Does that meet the requirements of the regulation? What else am I not telling? Or I am missing? I look forward to your comments on any side of the equation. And thank you in advance to for them.
