I recently had "MAX Turbo" service, which I believe was 24/5 (not sure which actual provision/profile it was on), which appears you cant get anymore. It was on a single pair (non-bonded), and I am about 0.2mi / 1,000ft from the local VRAD if you follow the long way on the streets (so it would be shorter as the pole goes, but then im sure there is some extra line anyway).
Service was working great, but I recently saw that "Power" 45/6 service was available, typed in my address, and it said I could upgrade. Called up AT&T, put in the upgrade order, and completed.
Unfortunately (I wish I had thought of this) I didnt take line stats with my 3801HGV + UV Realtime before disconnecting the service. I wish I had now, for a baseline. I had no issues getting 20-24Mbps / 5Mbps service though.
Back to my upgrade...
Last Friday, the Prem Tech came out, and this then became a little more complex. He said that my 2nd pair, for the bonded pair, was not activated, so he had to wire some things at the NID. After doing so, than installing my new 589 RG, and not getting anything to sync up, he came to the conclusion that while AT&T had activated the 2nd pair, it was somehow configured now as two single pairs, not a single bonded pair. He went to the VRAD, configured something, then came back 2hrs later and said it was still not activating/syncing. We rebooted the 589, and it still wasnt. Next, the PremTech climbed up the the Service box on the telephone poll by my house, changed some wires, and we went back and voila, activation/syncing occurred, and service came up. Did a quick speed test, and it was about 20Mbps/2Mbps.
The PremTech said that AT&T must have screwed up the profile provisioning, and that he would call Tier2 support. In the meantime, he also filed a ticket to have a INR/LineTech come out on Saturday AM to take a look at things, just to make sure. By the end of Friday, Tier2 had still not taken his call, and he said to call him back on Saturday. For the meantime, I at least had functioning internet, but slower than I was paying for.
On Sat AM, the INR came out, went over to the INID, and said that the PremTech had wired something incorrectly, clipped something off the NID, re-wired something (didnt catch what) and then drove over to the VRAD. Did something (again, didnt catch what), came back and said that it was now getting better signal, but that the profile needed to be changed. Service was still working at that point, but the speed was not changed (still 20Mbps/2Mbps).
Fast forward to today (Monday), the original PremTech came back...finally got Tier2 on the line, and then finally managed to switch the Profile to 55/6 for the 45Mbps service. the NVG589 would boot up, activate both lines for a split second, and flash red, then re-sync. It continued to do this indefinitely. Eventually they dropped it down to the 32/5 profile, and things seemed to stabilize. We tried swapping back to the 55/6 profile, but things didnt sync again.
PremTech claimed that if we kept changing the profile, it would degrade the line quality permanently (I called BS, how can changing the profile degrade the line quality in an un-recoverable way...doesnt make any sense?). Anyways, I now am getting the line stats in the above image, which seem quite poor. I had the following questions:
1) Do the above line stats make sense for 1,000 loop length? They seem extremely low. Is there anything the PremTech may have missed?
2) If those stats are correct, is there anything the INR can do do improve the SNR values?
3) How is the DS Max Attainable rate on Line2 less than the sync rate?
I could have sworn my SNR values were much, much better in my previous config. My understanding is that the higher data profile you move to, you drop SNR. Is that correct? At what rate?
Thx.
