Hey Folks, Hoping to get some insight into this problem I had with an Adtran HDSL circuit. The sucker has got a new doubler, new smartjack, and no apparent cable issues. Not even any bridge tap (I NC'ed it to cable and the cable tech found it had already been cut off). Anywho.....it always passes QRSS yet it will fail 1 in 8, all0's and all1's. BUT it seems to pass one of these 3 patterns, then fails the next intermittently.I gave up and patched to the spare. I'm new to specials (4 months) but I've never seen this before....any ideas?
