Don’t be so smug. I am certain your company has counterfeit components in its equipment. The “monitoring of the supply chain” is a complete joke! They inspect paperwork and do QC testing, not teardown and crush inspections of individual components from sub-contractors whom they have no oversight of.
No company makes all its parts. If you had any idea of the number of manufacturers contributing parts to communications equipment you wouldn’t be so confident in your company’s equipment.
Putting devices inside commercial communications equipment for the purpose of espionage, control or sabotage has been going on for decades, mostly by the West. Now it’s being done by China with components going into US systems. But you don’t think anyone could do that to us? Pure hubris.
Actually, since my company makes all of the chips of consequence inside our products I am certain in what I say. Regarding the other chips, it is is irrelevant. Ls, Cs, Rs, Es, SOT23, etc, cannot be used for espionage. Our PAs come from the OEMs. What we do get via suppliers cannot be used for espionage.
I am not saying that it cannot be done and that the US should not be doing it, I’m just saying it does not happen in my companies products.
