It has varied from 7000 to 400 down sync thsi morning with numerous drops, and SNRM has moved between 9 and -2 dB. WTH could be going on? is there any clue from router's log and other info attached?
-
Could you attach Hlog and QLN?
-
Sorry, they've gone, cleared automatically.
-
snr dropping means some kind of noise, if your sync is going up and down this backs up the variable amount of noise, other then that I cannot say sorry. No idea what type of noise it would be.
-
I didn't want to start another thread. ( hears tentative sighs of relief ;D).
Monday and Tuesday were gruesome with 20+ disconnections.
Errors yuk!
23 Jan 2018 20:15
CRC errors per hour: 1196 Down, 43.4 Up
FEC errors per hour: 1408 Down, 670 Up
HEC errors per hour: 7557 Down, 171 Up
ES per hour: 99.0 Down, 16.0 Up
SES per hour: 62.7 Down, 0.91 Up
The Mills of Ren grind extremely slow. At last I connected to the test socket, and now no further disconnections, and errors:
Average error rates for 24 Jan 2018 11:35
CRC erors per hour: 1.72 Down, 0 Up
FEC erors per hour: 183 Down, 37.9 Up
HEC erors per hour: 6.09 Down, 0 Up
ES per hour: 1.37 Down, 0 Up
SES per hour: 0 Down, 0 Up
So, it must be a domestic problem. Is it worthwhile to attempt to trace source before I get man in, or best not to?
-
You've likely posted it elsewhere but could you post a description (or a link to a previously posted description) of what sockets you have and what is connected to each socket please.
-
Assuming you mean for DSL only, master Nte5 in hall and hard wired extension through cavity to room directly above.
A time ago I did post pics of the sockets' innards, and IIRC B'cat remarked on the extension not being standard. I've searched extensively, but no luck.
Edit:
Master: answerphone via filter
Extension: computer via filter
(Those are the "as usual" details. Temporarily all is wireless).
-
Do you use the phone side of the filter in the room upstairs?
What is the wire that goes between the two sockets (how many cores)?
-
Upstairs is normal extension with a dangly in. Only BB side is occupied, as room has DECT slave connected to power socket.
I thought it was CW1308 from previous discussions. I'm clueless re cores.

I had to search through many pages of your past posts but I think I've found the one in which our discussion began . . . I believe it starts here (http://forum.kitz.co.uk/index.php/topic,19703.msg350627.html#msg350627).

Where the extension socket is only going to be used to plug in a router/modem the best way is to have a filtered faceplate in the master socket, connect a twisted pair (one pair of your CW1308 wire) to the xDSL (AB) connectors on the back and then at the other end have a straight unfiltered dedicated data socket in to which you plug the router directly.
-
I'll be contacting a local with that in mind. Thanks. :) ATM I'm ADSL. Could Cat 5e be better, especially for possible upgrade in mind?
-
If it is proper twisted pair it's unlikely changing to Cat 5e would make a significant (if any) difference.

Thanks for that confirmation, jelv.
My master socket is in the garage, and my modem/router is at the far end of an internal phone line that goes both upstairs & downstairs, with several outlets along its length. At least some of the sockets are daisy-chained (two cables to a socket), but I don't know if they all are. If you look at the latency graph (Westie) on MDWS, you will see it's not the cleanest of lines.
I'm due to change to FTTC in a week :fingers: and I've been concerned about noise from the internal wiring. I happen to have ~100m of BT 4-pair 0.5mm cable and I was considering running a separate line direct to the modem. I know it's not cat5e standard, but it should cope with 40Mbps shouldn't it? :hmm:
-
Thanks, B'cat, (belatedly) for finding old thread and pics, and jelve, for advice re cat 5e.
One little thought is to replace Ethernet cables of indeterminate age too.
-
@Westie - as long as the wire is twisted pair it should be a distinct improvement over what you have.
@renloup - until an Ethernet cable stops working or needs you to waggle the plug in the socket to get a decent connection it's fine. Standard Cat 5 (not 5e) will work up to 100M at 100mbps so the short lengths you have are very, very unlikely to affect speeds.
-
Thanks, jelv

Man is coming tomorrow. This afternoon, at request of Erin, I recovered the router (Billion) from test socket. Back in its usual home it acted straightway as before, so it was back to the Technicolor. That's holding in but under 3000 kbps.
OT. I was surprised by another contact, claimed to be ex-BT, who in his email said, " I don’t recommend fitting the filtered kind of sockets as filters are prone to just break for no reason and this can cause you a problem with testing and replacing easily".
-
The man came this afternoon, and saw the layout. He seemed unsure about testing for source of trouble, and suggested replacing the wiring in the cavity. I may have misunderstood along the line, but my talking about two cables being run from a SSFP, he said only one was needed. He looked to be getting on. So not broadband savvy?!
Comments for ren, please.
-
Assuming you decide to have the cable that links the NTE5 (master socket) to the telephony extension socket (and the yet to be installed data extension socket) replaced, it can be done in two ways.
Either using multi-pair cable, say CAT5e (which is four pair cable), and running the telephony circuit over one pair & the data extension over another pair within that cable.
Or using two runs of cable, say two pair CW1308, one cable for the telephony extension & the second cable for the data extension.
Hopefully the above will make sense . . .
-
Thanks Bcat! It seems from your advice I may have misunderstood the man, eh!
Have you any feeling on the two contacted so far?
-
It is very difficult for me to constructively comment.
If you have decided that you would like to have an NTE5/A as the master socket and then have the most recent SSFP Mk III (service specific face plate) fitted, with two separate sockets (one for telephony, the second for xDSL) at the original extension location, then that is your choice. If the person you have contacted does not want to do it as you have requested then don't use him.
-
There are many variants of CW1308 cable with differing numbers of cores so it is perfectly practical to run separate data and telephony links over the same cable.
E.g. Maplins sell 4 and 6 core: https://www.maplin.co.uk/search/?text=cw1308; (https://www.maplin.co.uk/search/?text=cw1308;) RS components sell 40 core https://uk.rs-online.com/web/p/telecom-cable/0368479/ (https://uk.rs-online.com/web/p/telecom-cable/0368479/); you can even get 100 core (Google CW1308 50 pair)!

b*cat nods in agreement.
Some people take the view that once the xDSL and telephony are "separated" at the SSFP, it would be preferable to use two separate cables as a means of keeping the two signals physically further apart.
-
B'cat has been very kindly informative in an exchange of PMs. I am waiting for my chosen expert to make a time to call to deal with problem.
Connection has been getting much worse, with one idiotic episode caused by YT. I had tried another DSL cable, and somehow managed to insert the RJ11 in the adjacent RJ45 socket. ::)
This morning the QLN too had much changed. Here are text results for yesterday and today.Tone 05/02/2018 06/02/2018

Are those figures telling anything?
I've changed back to the Technicolor 582N, which seems to be holding in. However, there is a glitch with DSLStats. It doesn't like the password, I use to log into the router with as DSLStats' telnet password. It didn't seem to like blank either.
Comment and further advice, please.

The man came today, and now I have a NTE5C in the computer room, and the downstairs socket is relegated to an extension. Labour +parts was £41. I forgot to ask what he was using, but he said line was clean. I'd guess the apparatus was near to the that of a legacy digibox, 4 cm high.
It's 5.25 hrs uptime since the work, and just in case someone spots anything

I dont expect marvels yet, but should I request bamding removed now or wait a bit?
-
I would be inclined to just use the circuit; watch and observe how it behaves over (say) the forthcoming week.
Looking at the raw data does not tell me much. I can see that in the current "up" time frame there have no CRCs or other "nasties". The number of FECs is quite reasonable and shows that the error detection & correction functionality is working well.
-
In my last post I said
the downstairs socket is relegated to an extension.
. That was the old master with the horizontal split. What is there has the split, so I'm guessing the old master is acting as an extension, but with a test socket still in situ, but non operational.
Fusspot I know, but I like to be sure of things.
-
Oh . . . ???
So I'm uncertain as to what your man has done. If it was me, I would have replaced the old master socket with a new extension socket. Unfortunately Hampshire is just too far away for me to "drop in" and check.
-
He's ex BT in his ads. I could unscrew the socket, take photo and post if thought useful and wise. :-\
-
Perhaps that is something you can defer doing until a later date . . . or until you find there does appear to be problem.
-
If this morning's record is something to go by, I wonder.

What does the checker (https://www.btwholesale.com/includes/adsl/adsl.htm?s_cid=ws_furls_adslchecker) say your line rate should be?
Are you graphing SNRM with dsl stats. Is there anything in there which looks a bit REIN like?
-
Number and address versions give different results, but I'm pretty sure number version used to give higher upper figure. The drops seemed to start in morning work hours and stop ~7.30 p.m, since when all has been quiet.
Selected graphs are attached where something notable occurred, variable as I was playing around for suitable scaling.
I had thought "router failure", and neighbour has work doing, but nothing happens when the pro is in. Son though I'll have to ask, as may be using deceased father's old equipment.
-
Image is a bit blurry (or my eyes are!) but since you are syncing at Downstream rate = 3069 Kbps, then you are below estimates and hopefully your ISP should be able to help?
The SNRM graphs don't particularly paint a nice picture and could be indicative of some sort of REIN. I would be sending those on to my ISP if I were you.
You and b*cat seem to have already covered everything I can think of and Im not sure if there is anything else you can do. :'(
[Moderator edited to correct a typo.]
-
The last set of stats, from 15 February, suggest the line is still banded at 3Mb. I would not bother watching stats and waiting for the banding to remove itself, just ask the ISP to remove the banding. Those stats looked bad, but I don't really trust a lot of the stats while banded.
-
@ kitz One problem is that the incidence of the bad patches is sporadic rather than chronic. I don't think I helped myself by swapping routers in case the Billion was failing helped given the Tech 582N gives less info.
@ejs Yes. it is around the top of a banding. B*cat did actually advise me to wait a week once the re-wire had taken place, then contacting ISP to remove it. The upstream Interleaving depth has gone from 8 to 4, but down is still 416.
Question: which is more resilient vs REIN- ADSL or VDSL?
-
I wouldn't jump to the conclusion that it's REIN. But generally I'd say VDSL would be more resilient.
-
I have now asked for the banding to be removed, but, pieces of earth law, this morning with Ren snug in bed, there's a disconnection and SNRM leaps. Does this system log extract say anything worthwhile? All I see is a lot of daemons.

A line with only 46dB loss should be a lot better than 3meg download. For reference we're 55dB and sync at a bit over 4meg when nothing's broken. However if your SNR has jumped up, than sounds like banding's been removed, maybe replaced by a high noise margin target. I'm basing that on the fact that when our line was banded its showed as reduced speed without a higher SNR.
Can you over-ride SNR on your router? The other symptom we found when banded was that over-riding made no difference to sync speed.
-
@aesmith and others I can override the SNRM setting, but as my connection is banded, possibly in ignorance, I don't see what such tweaking will do. Indeed might it make matters worse? I am waiting for the ISP's response to request to have banding removed. Today.up to 1 p.m. DSLStats has 3 entries of DSL connection being restored.
@B*cat Man confirmed old master has been modified. I tried taking photos this morning, but they're pants. I'll try again. I saw a couple of gel crimps after the top half was removed.
Question for all: Even though banding has made speed static, bit loading now is only covering tones to ~180, but yesterday 300+. Why?
-

If your line is banded, and it behaves the same as mine did, then tweaking the SNR will change SNR only and not the speed. For example when mine was banded at up to 3068K it connected at 3068K/6dB. Change the router setting to 3dB and it connected at 3068L/3dB. All I'm suggesting is that if your SNR is high it might mean that the banding's been removed but replaced with a high SNR target. Three disconnects during the day doesn't sound good, did they all reconnect at exactly the same speed?
Question for all: Even though banding has made speed static, bit loading now is only covering tones to ~180, but yesterday 300+. Why?
Is it now running ADSL2 rather than ADSL2+?
-
