Worrisome Dmarc Wiring KyleAK 03-22-2007

I recently encountered a customer with a Dmarc and associated wiring
that has me a little worried. Here is a photo of the area:

http://www.digitalsonance.com/dmarc.jpg

I was standing in a pool of water when I took the photo (for some
reason there are drainage issues on that side of the building). None
the less, the amount of exposed wiring and the Telco's choice of
location for the NIU for the customer's T1 data line are a bit
frustrating. My worry is that weather (or someone with a pair of wire
cutters) could do a significant amount of damage that could bring our
operations down some day.

I already know I need to completely rewire from the Dmarc back to our
wiring closet (the wiring is old and in much need of replacement after
being weathered for so long), but I'd like to get all this taken care
of in one shot. Does anyone have any suggestions as to the best way
to remedy this situation?

Thanks.

This doesn't look too different than tens of thousands of other
installations..

The NIU would be built for the weather.

Its all about how much you want to spend to get your peace of mind.

The ultimate would be to pay electricians/Qwest to move the demarc
inside the building. This sort of job would probably start around $2-3k
and go up from there though.

They'd probably want 4" conduit to go back to the handhole/manhole,
and then you could move your arrestor block panel & NIU inside, and
rewire it all.

Next level down would be to put your exposed wiring into some conduit.
Electrician could probably do that for some $hundreds. Looks like the
original electrician snuck the wire in around some water pipe, get
some decent conduit through the wall and up to the panel.

The demarc is the responsibility of the building owner though, not Qwest..

If things are super critical though, you may want to think redundancy,
although in this case, it might not make alot of sense.

I agree with doug. this is typical. get a piece of conduit and attatch it
to the building. you should be able to find something at your local
hardware store. I assume that your actual d'marc is the smaller box on top
in the pix. is that a padlock i see.
