Hi there,
I am living in Germany and German Telekom has diagnosed a "fault to earth" defect of their buried cable in our street last week. I had an excellent working Supervectoring line since I ordered it on November 13th 2018: Full-sync, 309 MBit line capacity on my brand new Fritz!Box 7590, excellent SNR margins of 11 and 12dB. German Telekom is going to repair the defective "fault to earth" part of their buried cable the upcoming week, i.e. a part of around 2m to 3m of the whole buried cable. So far so good.
BUT: Since May 16th 2019 the whole side of our street were hit by a sudden DSL-resync at the same time (16:39:59 o´clock). Since this time the Supervectoring frequency range above 17,7 MHz collapsed half-part. Please see attached image for details.
I have a dozen telephone conversations behind me since last week, but no so called "expert" at German Telekom knows what component in their Outdoor-DSLAM might have gone defective. All their remote management systems show no sign of any defect. So, they do not plan to repair their defective component in Outdoor-DSLAM.
Question to you guys: Which component in Outdoor DSLAM might have gotten hit by the "fault to earth" defect? I only know that I am connected to an Adtran Linecard 192.85. All neighbour hourses are affected by the defective frequency range above 17,7 MHz as well.
TIA for your advice,
Achim
