Rob W1AEX U-Verse is ADSL2 over two bonded pairs which by frequency begins at 26KHz and caps out at 2 meg. As for mitigation AT&T is going to have to get an transmission engineer involved to isolate why the RF is getting into the loop as thats why we pay them (engineers)the big bucks.

Currently, these other goodies are being deployed in various places: VDSL utilizing 1.1 - 12 MHz over twisted pair VDSL2 utilizing 1.1 - 17.66 MHz over twisted pair VDSL2+ utilizing 1.1 - 30 MHz over twisted pair None of these appear to have much ability to reject ingress from RF or random electrical noise. Their current solution appears to be to deploy new STB's that will buffer several minutes of programming to allow time for retransmission of packets to correct errors in the video downstream. They are also diddling with using shielded CAT5 instead of twisted pair, but as far as individual subscribers living next to a ham radio operator, they currently don't seem to have much to offer at this time. edit: spelling -- My Jeep is not an SUV.
