Oh sure…
The day the Bell guy has to come over to examine the phone lines, the system miraculously starts working again. Actually, I did add a ferrite core snap filter to the phone cable that runs from the wall to the DSL modem. I also snagged some twisted-pair phone cable from work and put RJ-11 modular ends on it, hoping that it would help cut out any EMI/RFI which might be affecting the system. Surely this wasn’t what was causing the dropouts and loss of sync on my system?
