    Oh and uh if the phone rings while your splicing I think it sends 110v. It will wake you up for sure.

    i'm so sorry about the baby ed, so very sorry.

    you use the end off of a line cord with the rj11 jack adapter, strip an end to connect the 521 to and insert the rj11 into the modular jack in the interface.

    first you have to disconnect the line cord to the house, replace it with yours and locate as usual.

    another way is to connect to the b-box or interface ground with the 521/pro-700 (you do this the same for live power) and locate normally.

    if you are really congested you can run the cable sheath, connect to the cable with a self piercing clip or (best) strip a piece of the shield back.never connect the TDR to any phone line unless it's a spair pair at the pole.





    again i'm really sorry about the baby

    Inductive clamp is much easier.

    90 volts for ringing. Sure to rattle your teeth. Wear gloves.

    i have an inductive clamp for my dynatel but not a 521.

    1748khz is a lot higher freq than most couplers use 300 - 1000khz as it bleeds to everything on the site, but it is great for blind sweeps of utilities.


    once you make the rj11 it's a matter of pulling one out and replacing it with yours.

    Once you cut the underground feed, you disconnect the feed from the house, and that gives you a dead wire to follow, once you inject your signal. This would be just as true for cable TV as it is for a phone line.
