A320: mysterious p/b or ANN

[FLX/MCT]

Hi,

I recently wondered what the function of the very outboard button or announciator next to the Autoland warning light is, which lights up blue on the pic?
Unfortunately my FCOM could not answer this so I think that it must be a newer function...

Any Ideas.....?

Thanks for your help and regards from LOWL
