may allow access

seems to me that this may very well be much more than 'fake' kit.

i mean, if it looks and works the way it's supposed to then it's feasable to think that just maybe they have some interesting additions/modifications that allow access to the dodgy 'maker', as suggested in previous comment.

think about it... if China wanted easy access to USA fbi (and other sensitive) networks.. all they would have to do is to manage to sell fake (but convincing and fully working) networking gear to them to implement on their networks...

once installed, bingo.. covert access achieved. and what's more, perhaps the makers of the fake gear are able to do other things like shutdown the devices..
