Hi All
My DSLstats are now available to look at on MyDSLWebStats. CrazyTeeka is for Line 1, CrazyTeek2 is for Line 2.
Comments on line(s) quality welcome. :)

Oh hello, Teeka.

Hi AlecR :)

Hi All

Comments on line(s) quality welcome. :)
Both lines are apparently the same though despite differing user names which isn't allowed. Both have the same upload IP address. One will get kicked off after a while if they don't differ.
-
These stats are from two different physical routers/different lines, two instances of DSL stats running on one PC hence the same upload IP. Why is this not allowed, am I suppose to run 2nd DSLstats from a totally different PC?

In that case yes, that's what I do. Are they not both Andrews & Arnold then as that's what comes up of course.
I'll flag it as an exception for the moment.
-
Yes, I have two FTTC lines with Andrews and Arnold. :)

Okay but seems a bit odd to rely on one line for stats on both. If that line goes down you'll have no sight of what happened, if anything, on the other line. Or are they bonded in some way, either by A&A or locally by software?
-
The lines are bonded as one, they share the same IPs. The firebrick router my side handles the bonding, along with config A&A side. If either line fails, the other line takes up the slack. The two ZyXEL routers operate as a bridge modem for FTTC, I have configured my network so that both instances of DSLstats can monitor its own ZyXEL router and upload the stats to the correct account on MyDSLWebStats.
So after discussing my setup, I wanted to ask the important question what sort of fault is occuring on line 2, and does line 1 look ok or not? :)
-
How is the fault on line 2 affecting your service?
-
Line 2 resyncs or SNR drops to 1db and PPP session cannot connect.
-
Have you tried swapping the modems to see if it stays with the line or the modem?
-
I'm going to ask about RJ11-RJ11 cables, do you use a UPS, get rid of microfilters and phones + extension wiring, the usual stuff...
Will you ask the A&A guys for their opinion?
-
Those SNR dips on line 2 look a bit odd. Its almost reminiscent of what you'd see happening on the upstream if there's a HR fault.
Is there any telephony on that line. Can you do a Quiet Line Test?
-

I will try that at some point. :)

I'm waiting for two RJ45 to RJ11 DSL cables (1 meter) to arrive in the mail, going to see if those help. Don't use an UPS currently. No microfilters or phones or extension wiring, I actually use printed DSL only face plates provided by A&A, as theres no PSTN service on these lines, only copper pair.
A&A know about the fault, and they know that I'm trouble shooting things my side first.

No PSTN service on this line, only copper pair for VDSL. Quiet Line Test was clean, even got A&A to email me the mp3 of their recording and I looked at it in audacity, was clean visually too.
Also -> A&A's PSTN Test is OK, End to End VDSL Test is OK, BT Knowledge Base Connection Test is OK.
-
No PSTN service on this line, only copper pair for VDSL.
I suspected it may be, hence asking if there was a way you could do a QLT.
Glad that AAISP has already explored that option, because those spikes do look a bit similar to what you could see if the phone rang/was in use if a HR fault was present.
Another possibility is REIN :(
.... although you'd think that would also affect the first line ???
-
I hear what you say about no PSTN, I wonder if there’s a chance that BT* didn't obey A&A’s instructions.
Could always try dialling in to that phone number (if exists?) while watching to see in SNRM drops.

To do a QLT, I usually plug in my test phone using a Phone Plug to RJ11 adapter into DSL face plate, when I pick up phone a recorded voice announces line number and circuit ID, then does a QLT, A&A record it their side.
I have considered REIN, I have an AM radio and ICOM Radio Scanner, and have been monitoring 612 Khz, there is some noise present in the air.

I'm waiting for two RJ45 to RJ11 DSL cables (1 meter) to arrive in the mail, going to see if those help.
If those are solid copper cables, infrastructure not patch, from Mr Telephone, they are useless.

It's these - http://www.amazon.co.uk/gp/product/B00B9G40QE

They look flat rather than twisted-pair

Can you explain why?
I'm not disagreeing with you I'm just curious.
-
They look flat rather than twisted-pair
I'll know once I try them, if they make things better or worse, the main reason for purchase was plugs either end that fit snuggley into router and face plate, out of interest what cables would you recommend? :)
Another question on my mind is are BT80B-RF3's safe to use on FTTC/VDSL lines?
-
I bought a UTP RJ11-ended cable from Kenable which turned out to be cca not copper, so I tried Mr Telephone solid CAT5 RJ45-RJ11 which turned out to be worse. I think Tandy do High Speed RJ11 DSL UTP copper patch cables which is what I'm really after.
-

Wouldn't you be better off with the OR Mk2 or Mk3 faceplate?

Why was it worse?
From what I understand, solid core cables perform better than stranded?
-
stranded vs solid = "skin-effect"
-
I have the kenable ones. (0.5m, various lengths avail)
I have bought the tandy ones in the past, I was not aware there was a difference.
I’m assuming that there's no point in having a SSFP filtering faceplate since there's no LF to filter as no PSTN and no filter means no possibility of inline attenuation caused by it.
@dray - re: "cca" - not ideal of course, but mine are only 0.5m long, so the resistance is hopefully low anyway (esp compared to my 4+ miles of copper). out of interest, how did you discover the composition of the two cable types?
-
So wait, I want stranded cables?
-
If you check out MDWS you'll see my line had a few issues yesterday, so I removed the Mr Telephone cable and replaced it with my Kenable cable. I was thinking of either crimping an RJ11 plug onto a RJ45 patch cable, or buying the high speed DSL cable from Tandy.
-
Are you certain your issues are down to that cable?
-

I researched the supplier based on the packaging that Kenable sent me and found a description of the construction, then asked Kenable to confirm. Mr Telephone did a video on various cables including a flame test which caused a magnesium alloy cable to flare up, but the Tandy cable was fine.
-
Are you certain your issues are down to that cable?
Yes it's happened on other ones I've tried, and it seems to be ok now.
-
So wait, I want stranded cables?
Yes, I think they are designed to be used to connect devices to sockets, whereas solid cables are for infrastructure connections between sockets.
-
I use the same straight-thru rj11 faceplates from the A&A shop.
I had a very bad performance experience with some nasty ebay cables made out of STP CATx with RJ11 plugs put on by hand v badly, the twist wasn't maintained right up to the ends. Changing to the kenable ebay ones (I think), 0.5 m, made a very important improvement in DS sync rate, >20%.
But we digress, as this is would be the same for both modems, so while these are nice tips, I can't see how this addresses the issue.
Unless...
Mains cables touching / near to one of the rj11-rj11 cables, or the modem-to-router ethernet cable?
-
But we digress, as this is the same for both modems
We don't know that, do we?
-
I've just ordered one of the Tandy cables.
-

We don't know that, do we?
Apol brain error, I meant to say “this would be the same for both modems”. Assuming the cables are the same, and I'm also correcting my earlier assumption because indeed the electrical environment might not be the same because of proximity.
A further thought, internal wiring run? Have we asked about that? Could internal wiring be different, one cable up to NTE5 might follow a different route? [Extreme hypothetical example where a cable might even god-forbid be touching mains. (which I have seen personally)]
Could drop cables be different externally, joints, age, route, length?
BT change-point-of-entry was my dearest friend here.
-
Tandy cables look like the cable of choice. Might get some.
Out of interest, if I used some BT drop cable (about 0.5m) and stuck RJ45/RJ11 on either end, does that also work well?
-

I'm not sure - one for Burakkucat or the other learned ones here.
Also need to consider your point about RJ45 instead of RJ11. At the modem end? Does RJ11 not fit into your modem properly? V odd if so.

RJ11 end would plug into modem, RJ45 end would plug into DSL face plate. I prefer this, too many cables stick RJ11 on both ends. :(

Hmm . . .
I have a spare length (~2 metres) of CW1411 specification cable (Drop Cable 10) stashed away in the grotto. I would not attempt to fit RJ11/12 and RJ45 plugs to such cable. :no: It is very much like structured cabling i.e. rigid, not stranded, and also incorporates three steel "strength members" within the outer sheath. (More than once I have been "spiked" in the paws by one of those "strength member" wires. Evil, nasty things! >:( )
Attached, below, is a copy of the data sheet for such cabling.

Looks familiar! ;)
Serious question: Are you sure it has solid copper conductors and not copper coated steel? :-\ (I was "caught out" like that, some years ago, with a spool of "CW1308 cable".)
-

Just examined a cross section of the copper wire, looks like copper inside. Did not see anything that looked like steel. :)
-
I would simply recommend going for the tandy cable, least hassle, best performer, as one can't make them up with the nice moulded plug boots.
Burakkucat has rightly pointed out in earlier discussions elsewhere that these screened/shielded cables should have an external ground connection for the shield. The Tandy (former adslnation) website even mutters vaguely about the matter.
I notice that the A&A shop even points out that those straight-through plates have RJ-45 sockets on them, so I understand why CrazyTeeka might wish for the most snug fit possible, although I have to admit I never even noticed that my own A&A plates are not using RJ-11.
Perhaps you can't have quite everything. But there are manufactured products that are way more than good enough for ADSL/VDSL.
That's just my personal take on the (rather off-topic, mea culpa) modem cable saga.
-
Well my "LINDY 1m RJ-11 to RJ-45 Modem Data Cable - Black" just arrived and are now installed on both lines, testing them over a few days. :)
-
Getting back on topic, please keep us informed about how you get on, what you find out for yourself and what A&A have to say?
-

A magnet will disclose any steel content, whilst a flame will disclose any magnesium or aluminium content. ;)
-
Just finished installing some new "BT drop cable number 10" to replace old cable, it has had an affect on stats (SNR looks better), not sure if things are better or worse yet, hopefully better.
Quiet Line Test was totally clean on both lines. PSTN test OK/Pass. FTTC End to End Test OK/Pass.
I took my time and did a nice clean job of it, and put VDSL MK3 faceplate filter back on both lines.
-
> SNR looks better
Sorry, higher or lower?
-
Line 1: 5.8 dB down 6.2 dB up, about the same as before.
Line 2: 5.5 dB down 10.3 dB up, both are lower now.
-
So line 2 US target SNRM is the problem still, it should be running too slow. DLM punishment?
-
On line 2 DLM has locked profile to 0.128M-35M Downstream. >:(
However line 1 is ok at 0.128M-40M Downstream. :)
-
There's something quite clearly wrong with your second line - the SNRM has dropped from over 12 to below 5.
Can you leave the stats monitoring up for a full 24 hour period please as there's a large gap.
-
I agree, it cannot be wiring in house now, because new BT cable to master sockets, new DSL cable to modems, line 2 was playing up while on a HG612 so its not the modem.
And line 1 is pretty much fine.
-
If you could leave the stats up for a full 24 hour period I'm sure a full view of your line could be realised :)
-
I'm now using two Tandy High Speed RJ11 DSL Cables 1m from http://www.tandyonline.co.uk/high-speed-rj11-dsl-cable-1m.html
It has made things a little better. :)
Once my JDSU HST-3000c arrives, I can run some copper tests.
Does anyone know if the DVOM Leakage Test is safe from the test socket, or does it HAVE to be bare wires?

I think the cable is shielded so did you earth the shield?

I was not aware it needed an earth, just plugged it into modem and master socket as normal.
-
Does anyone know if the DVOM Leakage Test is safe from the test socket, or does it HAVE to be bare wires?
If you perform measurements through the test socket you will have a series connected 1.8uF + 470KOhm shunt across the pair. Hence the recommendation is to use the bare wires of the incoming service feed.
-
What do BT engineers normally do to get bare wire safely when the wires are too short to cut any futher?
-
I suspect they attach more wire using gel-filled crimps.

Or just use a BT80A (http://www.ebay.co.uk/itm/BT-80A-JUNCTION-BOX-BLOCK-TERMINAL-BT80-BT-80-/261265014584?hash=item3cd49bbf38)?

Ah, I was clearly not in possession of all the facts. ::)
For one service feed cable, with two active pairs, then a BT84A (http://www.ebay.co.uk/itm/BT-84A-JUNCTION-BOX-BLOCK-TERMINAL-BT84-BT-84-A/261152097952) would be the best choice.
I presume you propose to run a new length of CW1308 cable from each of the two NTE5/A back to the BT84A and make use of the IDCs for those links? Then you could make a one turn loop of the existing service feed cable (thus leaving ample slack for any future adjustments) and connect each pair to its respective screw terminals. :-\

I've tried the Tandy cable (0.5m) and compared it to my 0.5m CAT6 cable from Mr. Telephone.
The CAT6 cable consistently allows the modem (Billion 8800NL) to sync 2Mb faster.

That's very interesting. Quite the reverse of what I found. But you and I are clearly in different worlds, as 2Mbps is more than my entire line's throughput!

From the second DVOM screen-copy, I can see that the A- & B-wires of that pair are reversed. (But it makes no difference to the operation of the circuit.) ;)
Do you have copies of the JDSU documentation? If not, I can make a copy of what I possess available for you to download.

It most certainly is. :D
I just use a DMM, set to the 200V DC range. The +ve probe is connected to a good earth and the -ve probe is connected to each wire of the pair in turn. The B-wire shows the biggest PD wrt earth and the A-wire shows the smallest PD wrt earth. The difference between B-to-earth and A-to-earth should (essentially) equal that of B-to-A. For the pair you have tested, above, it would be B-to-earth = 53.0V, A-to-earth = 3.6V (notice they both are positive values) and B-to-A = (53.0 - 3.6) = 49.4V.
Hmm . . . I don't think you can obtain a sensible reading for the AC balance of a pair with t'other end connected to the DSLAM/MSAN/exchange. I'm fairly sure that the remote end (remote to the end from that which you are testing) needs to be isolated. Perhaps Black Sheep will advise, when he has a moment to spare?
And, likewise, for RFL. (Resistive fault location.) :-\

If I was to do something silly . . . say connect my Ohmmeter 18C directly across the service feed and give the circuit the full 500V DC, I would expect the protection equipment to promptly clamp both legs of the pair to the exchange's protective earth.

Phew! ;D

When I use a BT phone in test socket I cannot hear any crackling on the line.
When I use 1st HST 3000's POTS phone on bare wire I can hear crackling on the line.
When I use 2nd HST 3000's POTS phone on bare wire I can hear crackling on the line.
Any ideas?
-
I would suggest trying another POTS phone :)

I guess I might need to buy a 2nd BT phone, as BT have a silly fault finding policy.
Sometimes I feel like banging my head on a wall proving there is a fault to OpenReach. :wall:
I'm feeling a little frustrated right now. :(
VDSL Logs Attached.

That's why it better to let the fault brew into a big fault a fault the OR engineer can easily see and fix if not you could expect upto 9 OR visits to find a small fault, it's just a waste of your time and there time.

Knowing OR anything better than no VDSL service is fine. ???
I guess drops in SNR (3db or lower) and resyncs and 27meg down from 40m, when the other line does 40m, is ok in OR's eyes. :(
I know it cannot be REIN as that would impact both lines. I can only assume i'm on a bad pair.
My ISP is providing a replacement modem/router to try, they have to follow BT fault finding policy to report a fault, sadly JDSU HST3000 results only count when done by OR, if i'm lucky my results may count for something.

I'm surprised you didn't just swap the 2 modems you have.
-
By the time you'd had 9 visits a D-side change and lift and shift would have already been done.
Now I don't know if that will help Teeka's line but from my experience its best to be persistent with Openreach. There are good engineers out there, you just need to find them :)

have asked myself a number of times why anyone would want you use such and expensive tool in a residential home other than being curious it won't fix the fault it's only a diagnostic tool used by OR to track were on the circuit the fault may lie.
That sort of tool would just frustrate me, being able to see a fault but not able to physically do anything about it, gezz the HG612 modem stats are enough for me ;D

I like to be different. If I get OR to come, I could say "Look what I got" :D

It's an OR lottery AlecR by time you found the one you have had 9 OR visits ;)
-
Five actually but yes I understand it was a lot :p

It's worked well for you your stats are impressive for a 750m line with 50Mbps sync and the US U2 band is back again even though with heavy interleaving on DS & US that's looking good :)
Edit: the US U2 band has gone since the last time i checked :-\

I do feel for you Teeka, I think you might be in for the long haul here buddy :(

I just want to say this line has never been right since it was installed. 1st it was on TT backhaul, could only get 1.5 meg. Then I upgraded it to FTTC - BT backhaul, DLM gave it a 0.128M-35M profile. I've tried a few modems, HG612, Billion 8800NL, ZyXEL VMG-1312-B10A. Moved the master sockets further away from routers. Changed the cat 6 to pure copper BT drop cable.
Monitored with MDWS, and a JDSU. Both found SNR drop/resync. But due to ISPs compliance with BT policy, I still have to try a new router, and prove its not my equipment, pfft I have changed enough things to prove this already. :wall:
All I could do now is fit new master socket. I have a feeling its a bad pair, or equipment in the cab/exchange is faulty.
Don't think its REIN, other line is fine.

Who's your ISP?
I'm surprised they're still asking you to try new routers and haven't sent an engineer out yet...

AAISP, but I think due to the type of fault, they still have to diagnose it the BT way. Swap this, power cycle that.
-
Ah well you should be in good hands then :)
I suspect TalkTalk would still be on that procedure if I wasn't dealt with by the CEO's office...

Update:
I have replaced everything I can, new cables, new master sockets, new MK3 faceplates, new modem on line 2, mr telephone cat6 cables going from AB IDC points on MK3's to DSL ports on modems. SNR went bad again from 20:42 to 22:02 on line 2. Still no noise on line. It has been raining today, its possible a joint got wet.

Please let us know what A&A next decide to do.

BTOR engineer due Monday 24th in the afternoon. No doubt he will not find anything. I'll have to get him to phone ISP.
-
My advice: get the ISP to phone you and then hand the phone to the engineer.
-
Indeed, as AlecR said. That's what I have done before.
-
Well engineer did not show. No doubt they will turn up when they feel like it now, outside of appointment.

May I suggest an email to Joe Garner?

Isn't that A&A's job, why you pay them the big bucks, to work the system on your behalf?

Yes. I was interested in how AlecR did it however.

I wondered if Openreach would take more notice of a CP than of a mere human ? :)

OR engineer came and fixed AC balance. Reset DLM. Waiting 14 days for DLM to settle. Getting 60meg now. Happy.
Engineers Notes:
Found low AC Balance E Side. Changed pair PCP Node 42 E-Side Termination: From 223 To 459 MDF Node 1 D-Side Sub Node: AQ Termination: From 723 To 959. Also found faulty LiC which was also changed. PQT, Closeout and Fasttest all OK DLM Reset performed Tested and Demo'd.

I don't understand all of that. Perhaps B*Sheep will be able to translate it for us?
I'm wondering what a "LiC" could be? :-\
-

So DLM can settle in less time?

Something related to dial tone I think.

It is a dynamic process (as its name signifies) and will react according to its analysis of past events, quantified as 15 minute blocks. (Any "settling in" time will not exceed 24 hours, if that!)

It looks like the sync rate has dropped from 60373 kbps to 45889 Kbps at 3pm.

Engineer did advise that might happen after a DLM reset. Waiting on DLM to stabilise things.
He also forgot to re-jumper to exchange so no dial tone.

When looking at your MDWS info the DLM has already decided that 60Megs is to much for your line and reduced the Sync rate there is quite a lot of errored seconds going on here so it's a 24 hour wait to see how high they climb and if interleaving kicks back in again.

Line Interface Card
I was wondering if that would be the "translation". The line interface card within the exchange. :)
-
Well someone has done something to crazyteeka's line this morning as the ES count has dropped the DS SNRM is much higher and the attainable is in the 60Megs :thumbs:
-
Line looks stable now but monitoring just incase. :)

TBH i don't call a line stable if you have to force the line capping commands it may get you out of the DLM red, to me it's just a false image of current line condition and it won't go away until your line is fixed :-\
-
Looks like SNR issues have returned. There were two big ones around 9pm and again around 6:15am. The other line was nice and stable. Assuming AC balance is still 62 on this line, there might have been multiple faults, fix one, uncover another.
-
I think it might be REIN.

BT Fault Please accept clear if fault resolved. If rejected an SFI appointment will be offered.

Twas a busted cable?

I'll go with AlecR there must be some sort of interference creeping in on that line, and if you had G.INP activated on your ECI CAB it would most definitely help to combat the interference the DLM see on your line :(
-
I forget, what is the interleave on your line?
-

It is now on 1283.

Hopefully you'll have G.INP enabled soon enough which should at least reduce your latency.
-
Interleaving has gone up to 1557. AC Balance still 62. TDR looks much cleaner.
On good line, AC Balance is 57 now, if its lower why is it resisting REIN better?
