Thanks for the replies.
I think youre right about it detecting DC current. I swapped the phone
line around and the same box is now causing the rectified loop on the
other line . I also have an identical sky box (Pace2500) that is used
just for the free channels and when I connect that to the phone line it
also causes a loop error so it must be a design of the Pace box.
If it does become a problem with BB then I will just leave the phone
line out, if sky get funny they can supply me with another box FOC.
