hio77: sooo, tech visited today..

turns out, hes not a vdsl tech. simply a tech filling in for another.. why a replacement vdsl tech wasnt set out for that, i really dont understand...

after letting him tinker for a good 20 mins or so, i went to him "urm mate, i dont mean to be telling you how to do your job, but as part of a vdsl installation, is it not mandatory to run a cat5e line from the ETP?"

he had to contact chorus previsioning to check this, responding with, it is a rental and so no cables are too be ran.

so after making him dig around, inspect everything.. turns out, out line is on the second pair of the neighbours connection, even though there are two lines ran to the house.

i was given the offer to have a cable ran from the hot water cupboard(yes, that wasnt a alarm line afterall) but then, its straight back into the rats nest of wiring that needs sorting so wasnt much point at all.

so, now we need to have chorus out, to do their wiring from the pole, and then vision stream can come back out to do the internal wiring...

oh and apparently this is one of the few areas with cable running to it, what a shame snap cant run us over that!

gfs comments are "maybe we should just move". this is getting absurd now..

waiting on the tech that came out to submit his notes so we can make any possible press on an update...

We will happily provide service for you

But hold on, you have a problem... we wonder where it's coming from (I know Telecom and Chorus are two "DIFFERENT" companies now, but I couldn't resist)

No, we've got nothing to do with it, it must be your wiring:

Yes, we can help

Hey Hio77, could you please post the link to the latest version of you stats grabbing tool? I'm sure it's probably somewhere in this thread but at 158 pages it makes it very difficult to find! If you consider it stable I'll put it in the main post.

certainly consider it stable, unless i missed anything..

I must get around to doing more work on it at some point though! have some awesome ideas i wanna pull out of the bag on it ;)

well, progress is progress i suppose...

chorus lodged their notes at 9.37PM...

with two points to follow up on,

firstly being access to the place, and the neighbours...

second being "may be further from the exchange than prequal shows" <- this point i had a little argument with the snap CSR over.. he double checked cabinets to see we weren't connected to the far away one, left it at yes, it should be fine.
i suspect this point wasn't worked out very accurately, considering the tech wasn't a vdsl tech at all.

time to give it 12 or so hours and press for another update.. oh joy chorus..

Anyone got any ideas what is going on here?? Some strange things afoot... Quite frustrated to have lost DLM-1 after a year of perfect VDSL.

For some reason the Fritz seems to think I'm on 17a. That's clearly not the case.
Dropped sync from 44Mbit down to 39Mbit
Dropped down to DLM-2
Gained bitswap on upstream
SNR on upstream has shot through the roof

This was all following a period of failed PPPoE. I've included a snip of the logs below. I've also noticed a switch from reporting Ikanos chipset at the exchange end to Broadcom. Seems very likely the linecard was swapped out that morning and the Fritz isn't as happy with the newer Broadcom linecard. That my attenuation hasn't changed suggests it's not my physical line.

I'm tempted to try the newer firmware to see if there's an improvement.. Anyone else on a Broadcom linecard care to comment?

Current stats:

Previous stats (had been like this since 11/2012 until the 20th Sept):

Excerpt from system log.. Note I don't have the previous sync as I (stupidly) powercycled the Fritz before taking a copy. At that point I'd had no PPPoE for at least 10 minutes but it could have been a lot longer as I'd only just noticed we had no internet.

Notice the 43Mbit sync fine (but no PPPoE) then 10 minutes later there's a resync and it's all bad. Rather dramatic change in line quality on a sunny morning!

thats quite a change in spectrum.. i suspect, a tech may have done a bit of a switcharoo..

clearly your fritz is showing that your only seeing 8b worth of spectrum..

maybe ask for a DLM reset considering this oddity and see what happens?

could try flashing the .22 firmware back and see what your stock syncs at, ild surgest avoiding the .51 firmware..

Seems very likely the linecard was swapped out that morning and the Fritz isn't as happy with the newer Broadcom linecard. That my attenuation hasn't changed suggests it's not my physical line.

The lower sync is probably a combination of DLM-2 and a considerable worse spectrum than you had. You've lost about 10db across the second downstream block and probably some off the first block too.

However you apparently have gained SNR on the upstream block - that's why the upstream SNRM has increased. Of course that is irrelevant since upstream is artificially limited to 10360 kbits/s. Don't worry about bitswap coming on - I believe it's only an indication that conditions on the line have changed (as they always will eventually) and not necessarily an indictment on the line quality.

Obviously the switch to the Broadcom card has caused the change. My guess is that DLM will put you back on DLM-1 eventually though it could take a month or longer. Getting a DLM reset may speed it up. If you do talk to Snap I'd tell them the Fritz is reporting the 17a profile but the spectrum is incorrect and ask if they can confirm that you should be on a 17a profile.

Still no update for my issues from Snap.
Sitting on 27/102 line attenuation still :(.

Have started to notice the errors.

well, waiting on a call back fron snap, queue is getting rather long for calls into chorus today apparently..

i had an image to go with how im feeling with all of this, i suspect it may fall into the NSFW category.. so i wont. :/

DLM is working its magic (seems DLM for this cabinet occurs at 4.08, slightly new time to get used to..)

im now almost hitting a symmetrical connection! i give it a few more days, and the upload will surpass the download...

anyone know if in this day and age, a telecommunications business actually makes use of the service they provide, and calls for permission to access neighbouring properties? or do they snail mail requests..

we actually had the tech that was here on monday let into the neighbouring property so that he could trace the cables and such.. nice elderly couple that hate chorus`s guts and spent the whole time spouting it! - something todo with their phoneline always cutting out... i wonder why...

Psilan: Still no update for my issues from Snap.

Have started to notice the errors.

just keep pressing for updates, you will get there eventually, i have noticed it depends on the CSR you talk to, some will request and update from chorus while others will put you on hold and directly contact. i suppose it is a sense of urgency sorta thing?

myself, im calling 2~3 times a day on average, unfortunately, its a common thing... techs dont put their notes in till the VERY end of the day.
you have gotta ask, why is it, that a tech is provided with a laptop and phone and yet.. they dont put their notes in after each job.. seems most of them go to writing things down in diaries!

edit:
and just as i post this, get a phonecall back.. work is being looked at, i suspect the notes i was read last night were completely unhelpful considering the contradiction in chorues resonance today.

they are on their way out today to take photos, and then hopefully we will know more - i take that as, they are actually planning the lead-in now.. ill be keeping an eye out for them, see if i cant rip anything out of them!

ah! we are making more progress here (while showing chrous's service level too..)

tech came out, looked at our cable from the road, and seems to think he can get our line over it..

he wants to talk to me about why its being done since speeds when a tech came out were "acceptable" (this would be the tech that came out midweek and didnt show up since he saw a 45Mbit sync at the cabinet - not paying attention to the fact that it was constantly dropping.)

missed answering the phonecall by a second, frustrating! what makes it more frustrating though, i was home, door wide open and all waiting for him. i didnt notice him doing his little checks, and instead of physically making a house call (afterall, hes here already, why not?) he goes back to the exchange to call me.. didnt leave any contact details apart from a name too.

isnt this what the techs are given mobiles for?

so, double edged sword i suppose.. gonna have to argue my case yet again, but progress is being made..

this is such an up hill battle!

in other news, im back at tinkering with my tool! graphs anyone? :D

Have you tried the magical 5min power off of the Fritz?

I spoke to Snap a few nights ago and mentioned the Fritz reporting the 17a profile. They said the card was reporting 8b. They requested a DLM reset. Have had a couple of resyncs. One of which errored like crazy which may have been DLM-1. It had already re-synced again before I noticed so didn't get to look at the stats. Seems to have settled back on 39/10 with DLM-2 as there hasn't been a resync in the last couple of days. Frankly with 5000 FEC and 1 CEC on DLM-2 I don't hold much hope for DLM-1.

Will keep see if anything happens over the weekend which will be the end of the 10 day period and get back on to Snap. To be honest I don't expect much other than perhaps they can lean on Chorus or AVM a bit. If this is a compatibility issue between the Fritz and Broadcom cards there may be a wider customer revolt coming...

No dice :( Gave it lucky 7 minutes just in case that would make a difference. If anything it's worse. Now hitting 5900 FEC (bitswap hasn't come on yet so perhaps that's why)

the ordeal continues!

no phonecall from the tech today, thanks for false promises again chorus!

so i pushed snap for a response at 7.30 (tech didnt call last night till 6.45, so i thought ild give him the benefit of the doubt..)

after snap called chorus to check up on things, call back to inform me of chorus's miscommunication, turns out, i was meant to organize with the neighbours access (this is something chorus were actually given when they were out on monday.. so easily enough done.) but i wasnt informed of this, or given a reference number/ phonenumber to actually do anything with.

nor had chorus updated my ticket at all, last update being the 30th...

so, now onto trying to organize access for chorus (inwhich its too late in the night to doso tonight, and we need details such as what sort of access and where they require to access - neighbours are nice elderly folk, but simply rather iffy about people going near their stuff)

tech is organized to call me in the morning, but heres the kicker.. the night staff that organized it, didnt even check he was even working tomorrow before actually marking it down and informing me it would be tomorrow morning!

if the simple process of is this tech in, yes, ok carry on.. isnt followed, its a nowonder chorus (visionstream in particular) are such a mess!

hopefully everything is resolved tomorrow morning, and we can be booked for our new wire from the ETP (yes, we are only talking a new wire from the ETP here!) saturday or sunday and be able to actually use our vdsl connection 2 weeks after the installation!

dare i be snide, and demand CAT7 or something overly excessive at this point? lawl..

as for the tool i have been working on, plenty of changes upcoming, everything will be graphable, recorded to a RRD file, also a few changes incoming for easier automation with things such as desktop manager showing the contents of a latest text file
