This fibre termination box is in my house. By tracing the fibre cable from this thing, the fibre cable from my house goes all the way into the TM box at the backlane. Unfortunately TM keeps telling that is "no port" for Unifi. The fibre cable from my house could have already connected to the TM box occupying one port there. As long as there is no technical guy do a site visit to open up the TM box to check, I'm not convince it as no fiber port.
