Well....FWIW.....you sound like you'll be alright. Lots of problems
can be traced back to poor installation. As long as you take the time
to do everything "right" you shouldn't have too many problems.<br>
<br>
An a seperate note: I can't remember if the limit on DS-3 was 450' to
the DSX-3 or total length of the cable run. A lot of the specs on DS
carrier circuits were made for runs to a cross connect inside a
building. You set the buildout for the length to the DSX panel and
then cross connects between arbitrarily distanced equipment inside a
building didn't require you to change the buildouts.<br>
<br>
Of course, I could be wrong. ;-)<br>

We are actually plugging into what they are calling a 'GID' Ground <br>
Interupter Device. <br>
<br>
btw: Several of the buildings here have HUGE bundles of coax between <br>
them.. all underground (like this will be)... no real problems (yet). <br>
<br>
Our wireless rack equipment rack (up on the third floor) is fed on <br>
isolated (floating) power, and has it's own VERY heavy grounding
system.. <br>
I've watched lighting balls crawl the rack.. and everything kept
working. <br>

Found Belden quad-shield outdoor (but not direct burial) RG-6 for <br>
