Since 11:30 Saturday morning, line three, having just been ‘fixed’ was constantly losing sync, with massive packet loss. Downstream sync speed dropped from 3.15 Mbps down to ~740k and upstream speed is now a miserable ~160k.

You need A&A to reopen the fault report to Openreach, if possible, otherwise submit a new fault report and have it escalated.  :(

I dropped a line to AA just in case they do not notice that that line is still very sickly indeed, frequent resynchs and syncing at low speed.

The clueless logs tell me that AA has left itself a reminder re this line - ‘needs a management review’ which hopefully means what it says on the tin. Sounds encouraging anyway, perhaps implies that they would have taken another look at it regardless.

It was actually all the way down to 300k downstream yesterday, because I had pushed the target SNRM all the way right up to 12dB in an attempt to put a stop to its constant resynching. It’s back up to where it should be now, at 2.68Mbps d/s @ dB SNRM.

Unplugged the modem from the line so AA could do some more tests.

Does that say 8.05 km? Really?

So, BatteryContact again.

And we talked about this before: why “The asset care level 2.5 will be applied rather than the specified service level” ? I can’t remember what we said that was all about.

Yes and no. Possibly circuit attenuation based. I suspect it is really more of a guess. Perhaps disembowelling a low flying raven, scattering the entrails and looking to see how they then laid was involved. I see to recall that Black Sheep looked at the network records and performed the sums, thus coming up with a physical distance between NSBRD and the Weaving Shed.

So it claims.

Sorry, I can't remember that discussion and so cannot provide any help or hints.

AA was unbelievably fast, just within a couple of hours, another one of our local OR guys attacked it again:

I completed the ring ahead but there was no answer (voice message left where available). I continued to progress to the end customer premises. End customer advised there is a broadband issue. I have resolved the fault located at the D-side including aerial cables / lead-in / block terminal. The fault was located outside the end customer's curtilage and shown by damp / corrosion to wire / cable. The fault was fixed by clearing in joint. No additional work was carried out on the end customer's wiring / equipment beyond the NTE at their request and within TRC banding. Engineer has not visited end customer premises. I performed final FastTest from the customer premise. The test passed on 10/12/2018 11:23:02. QBC Summary End

Hopefully all four circuits will now remain operational and stable for the foreseeable future.  :)

No such luck. Back to line 4 now. Total chaos on Tuesday, umpteen resyncs, so AA who were monitoring the line for me, just immediately got OR straight out and OR did some work on the underground copper yesterday. More chaos of course on the line followed. I had no idea that anything was even happening as AA handled everything. I was so ill yesterday, I was unconscious all day until about 02:00 this morning when the drugs kicked in.

This morning my wife got a call from an OR engineer on the mainland who said he was heading for me. I was totally unawares. As I wasn’t expecting any visit, not having yet realised about the history of problems, I got my wife to ask the engineer which DSL phone number. He couldn’t understand that because not used to there being anything more than just ‘your phone line’ singular. Struggled to work out which line this phone number belonged to. Eventually my wife managed to find a table of phone numbers and mapped from that to line #4. So apparently someone is due to fix an earth side fault near the house in the next few mins.

Superb job AA did for me, just handling everything while I was out of it.

The OpenReach loutish guy was very rude to my wife, churlish and ignorant. Eye rolling and I’m just here for phones don’t care about internet, or words to that effect, I forget the exact words my wife recounted exactly. My wife told him we don’t have any phones. Then, concerning my ISP, something like, there was nothing wrong - ‘They probably just made it up’ or similar. The most nasty guy I’ve ever had and unfortunately I wasn’t there so my wife had to put up with this yob’s attitude. I don’t think his employer would be very happy if they had overheard.

Why are AA raising phone faults if they only sell you an xDSL service.

An engineer who turns up for a phone job can't just change the job sheet and retrain himself for broadband faults while sitting in his van unfortunately.

The attitude sounds bad from the engineer, but when they say "I'm here for phones, not internet" he's absolutely spot on. He's tasked to fix the issue on his sheet.

Perhaps BlackSheep could explain it a little more but it's a very common complaint. It isn't the fault of the engineer, it's the ISP who books the task.

No need for him to be rude about it. A simple "I'm sorry I'm here for a specific task only" would suffice.

Might this be the fault of BTw asking for the wrong thing of OpenReach rather than AAISP?

I pay AA line rental. Don’t know if that is significant.

If something is sufficiently low-level and disruptive that it counts as a PSTN fault then that could be what it was?

This was, I am told, unsolicited mouthing off from our man at my wife who had never mentioned internet but he saw a router large switch umpteen modems etc and so volunteered this unsolicited statement of last century attitude.

I have just looked back in the event log in AA’s clueless. AA raised a PSTN fault on Tuesday.

Latest visits re cwcc@a.4 did not fix it at all. Still very unstable and downstream sync rate down to 1.3 Mbps, instead of ~2.8 Mbps d/s at 6dB target SNRM, or 3.1Mbps d/s at 3dB.

So the saga continues.

I’m wondering if I should reinstate ‘enhanced care’ on that line.

My feeling is that once you have reported a problem to A&A, you should not need to do anything more. You are paying a premium price for a service from a premium ISP (CP) . . .  :-X

AA are looking into line 4 again.

If anyone has any advice about this line, I would be grateful. Will post up more raw stats after latest repairs if requested.



On an unrelated matter, line 1 is no longer stable at 3dB downstream target SNRM, with between one and three resyncs per day. I have put it up to 6dB, which unfortunately has chopped 254k off the downstream sync rate, was 3.115 Mbps down to 2.861 Mbps sync rate. So 3dB is quite a big deal, gives me an extra 9%, shame I can’t quite sustain it on this, the fastest performing line, any longer as presumably the noise variation must be too great or the target needs to be just a little bit higher, say 4dB or something. I ought to capture somenoise stats over time on this line. Need to get the good Johnson embedded stats webserver installed in that modem.
