UM, Hi guys, My name's Jason (from Niagara region in Canada) and this is my first post. I just wanted to put my two cents in....

"IF" you want to trace all that wire (the 1500 ft), and you do find a fault or a bad splice, get a hold of some "burial splice kits" and "scotchlocks". Shouldn't cost too much.

If you do find a problem you'll be able to repair it on the spot and be fairly sure you won't get wet lines because the splice kits are gel filled just like the cable.

Some of my customers have problems in my area (out in the sticks) every time it rains at 3 locations in particular, but only on a few lines. These problems can include scratch/static filled lines and dropped calls. Telco keeps telling me it's fine.... but I've been fighting with them over this one for years. I'm gonna show them the definition of intermittent someday.

Be that as it may, good luck with your cabling.
