New minor event to report :)

This morning it looks like some work has been carried out I guess on another port/line, this caused temporarily my SNRM to shoot up, this happened twice, after the second time my SNRM is now lower.

The bitswapping which has been stuck for several days at a fixed rate has now since this change moved down to normal levels again, which is the primary reason I posted this update.

This is one of the reasons I didnt push for my banding to be removed, I think my line wont stay capable of the full 80mbit for that long, so if I had it removed I it would only serve to annoy me when the inevitable reduction of attainable occurs.

Seems to have affected your upstream most:/   Prior to this morning you were hovering 7.6-7.7  Seems to have settled back at 7.7 again now.
Your max attainable since the other week is the best its been in ages.

Looks like the speed checker database is really broken now for my address.

Clean High 21.5
Clean Low 15

Upstream

Clean High 1.2
Clean Low 0.8

Handback threshold 13.1

Is served by cabinet 78 on the checker, I would appreciate if someone can check that cabinet location for me :) So I at least know its using the right cabinet.

Thanks to kitz's excellent guide here http://www.kitz.co.uk/adsl/cabinet-lookup.htm#fttc_cab_info I have confirmed it seems to be using the same cabinet.

---

Another update, all the neighbours I checked served by the same pole have normal estimates, I thought I remembered black sheep saying the estimate is based from the pole, but for some reason my own address has a very low estimate.

The "guesstimator" data is based from the DP in question.

So do you have a theory why when on the same DP I have different results?

I pm'd you address info so you can check yourself, and neighbours.

My feeling is that one (or more) of the databases have become scrambled.

Something else does not seem right, to me . . .

You have mentioned cabinet number 78 but if I enter Leicester as the location, in the Magenta Systems CodeLook database, and select all 109 cabinets, then scroll down to P78 it shows --

Cabinet P78      FTTC doing Field Survey, live due by April 2018      Phase SEP Leicestershire 18b             Huawei       

That certainly doesn't match the live ECI equipped cabinet, to which your circuit is connected. Very puzzling.  ???

That's the Montfort exchange. My guess is Chrysalis is on the Leicester Central exchange. Need to select Leicester North on Codelook.

Thanks j0hn. I realised that and mentioned the above (correct) information to Chrysalis, in a PM, just before going to find my bed.

Due to lack of MDWS I got an update.

Lost sync just now, line stayed dead for a couple of minutes rather than an immediate resync. Also had no voice for the 2 minutes.

It came back, I did assume all was the same in terms of attainable, as I knew previously my SNRM had dropped to below 6db, and a resync would have me around 78mbit.

Now I am at 78mbit, but the SNRM is only 5.3, so attainable is now 2mbit down from immediately before the resync at about 76mbit, given the 2 min full on outage I am paranoid a tie pair swap has been carried out, although I am not sure if that would cause a voice outage.  US attainable is also down but given the varying natures of UPBO from one sync to the next I look at that with less interest.

Code: [Select]
Latest 1 day time = 13 hours 50 min 48 sec
FEC:            0               669
CRC:            9787            60
ES:             249             56
SES:            17              0
UAS:            117             106
LOS:            1               0
LOF:            8               0
LOM:            0               0
Previous 1 day time = 24 hours 0 sec
FEC:            0               664
CRC:            1064            60
ES:             428             57
SES:            0               0
UAS:            0               0
LOS:            0               0
LOF:            0               0
LOM:            0               0

Big spike of CRC and clear SES but ES looks safe for DLM purposes.

--edit--

Active SNRM and attainable is continuing to fall (other lines been reconnected?)

Just a thought . . .

I wonder if a G.9700/9701 (a.k.a.G.Fast) pod has been added to the PCP and in the process of connecting it up, the tie-cables to/from the DSLAM containing cabinet were disturbed?  :-\

Not sure- perhaps worth Chrys going for a small stroll to check out that theory.     I saw this post earlier but didn't have any answers :(
The decrease in SNRM after sync will obviously be another modem syncing after Chrys's but he will already be aware of that, so I had nothing useful to add :(
