Trying to troubleshoot what I thought was a basic problem. A DSL
modem installed in a construction trailer not working. There is a 6
pair outdoor phone cable feeding the trailer from the main building. 5
phones work perfectly fine in the trailer. For some reason I can't get
the DSL "happy" light to light up on the modem in the trailer. I
tested the modem inside the main building just before it leaves the
building and it worked fine. I swapped pairs on the outdoor cable, but
no help.
I know distance is not an issue because I tested that too. I "looped"
back the DSL line back down to where it comes in main telephone room
( basically doubling the distance) and it works fine. So I'm thinking
this is more of an inteference issue. Any ideas where to start? The
trailer is next to an MRI facility, not sure if that matters.
