Yes, the lines that are zip tied to the conduit lead back to the wiring closet, so I assume that is on "our" side since it is coming out of the dmarc. The box on top houses the NIU and smartjack for the T1 data circuit, which was installed by Qwest (they were the ones who ran the exposed CAT5 from the dmarc up to the NIU, then the exposed wire from the smartjack back into the building).
