This is the common little 1Gb/s ONT guy I'm talking about ... no jacks for phone services, just fiber in (on it's backside, 12VDC-power in and WAN out). You could even supply it remotely via PoE backed by UPS from the IT cupboard (I do).
You'll find it in each flat/house with FTTH regardless of the ISP's plan since his stuff (router h/w, IPTV, PBX, whatever paid/unpaid services) doesn't start before the WAN RJ-45 Link. When you are a granny which possibly refuses to have the full blown internet stuff, that's the point where an ATA for VoIP is connected to and all is done for fiber.
Sorry - but I can't correct the double pic in the post.
