No dailtone on the third floor...

["Moon1990" <kevin.jasey@xxxxxxxxx>]

I have a newly renovated home with cat5 cable run throughout (all
homeruns).  I get a dailtone from at least one of the rj45 jacks in all
my coverplates on the first and second floors but no dailtone at any of
my rj45 jacks on the third floor.  Could anyone tell my why this could
be?  How do I get a dailtone up there?

I've never done any stripping of telephone cable or wire punching but
from my research this seems pretty strait forward with the right tools
and if you are not color blind.

And in most of my coverplates I have two rj45 jacks.  One is obviously
for telephone but what could the other rj45 be used for?

Any suggestions are more than welcome.
