My reasearch about Hlog and cenzorship on forum.kitz.co.uk


[link to this post]
 
I have very unusual Hlog (attenuation per tones) on my ADSL2+ circuit.
https://s22.postimg.cc/tgbw5782p/hlogwitoutmask.png
I've discussed about it on many threads on forum.kitz.co.uk. However moderators haven't allowed me to write about my ideas.
https://forum.kitz.co.uk/index.php/topic,22097.0.html
https://forum.kitz.co.uk/index.php/topic,22114.0.html
I hope on this forum I can write about it and I can explain why I think burakkucat is wrong in this post.
https://forum.kitz.co.uk/index.php/topic,22097.msg37...

I realize that there are Hlogs precisions limits caused by granuality. However I think it weights in favour of my theory. Precisions limits cause that dip at ~110 tone is not noticable on other circuit Hlog. This Hlog have significantly smaller but the same measurement errors. Even my circuit had smaller than usual measurement errors at one day with one anomalous synchronization with SNR margin 15 dB and higher power output.

This is visible when I attach two graphs on one coordinate systemts.

Moreover I've discovered Hlin gives more accurate amplitude datas for first download tones.

What reason do they give for censoring you?

Because he's being banging on about it for years and has ignored numerous requests to stop pestering various forum members when they have done all they can to answer his questions.

In reply to a post by konrado5:
I have very unusual Hlog (attenuation per tones) on my ADSL2+ circuit.
Does the circuit work fine? As in sync speed and throughput?

If so, what's the worry? If not, have you discussed it with your ISP and possibly raised a fault?

Looks into history .

Is that still Netia, in Poland? As stated in your October 2013 post in this forum on the same basic subject. I note you also had this 2014 thread and importantly, from November 2013:-
I'm not complain about my Internet connection however I'm very interested in details of ADSL2+ technology. Could someone explain my issues?
I haven't followed any of your links in your opening post here. I don't see the point if your line is performing reasonably well.

Importantly, the quote I gave answers my first question, and with it being something happening in Poland we are unlikely to know what your ISP or its carrier may have adjusted in their setup of the circuit.

It is not reason to censor me. It is harm for potential interested person. Uninterested person can omit my threads. I don't agree to cenzorship.

Circuit works fine but it is unusual and I am interested what is cause of unusual Hlog graphs and other unusual characteristics.

Have you compared it with other users' graphs from the same ISP on the same DSLAM, and similarly other users on the same ISP with an identical DSLAM but not the same one?

If not, you don't know it is unusual for that ISP.

Comparing it with any UK Hlogs is not relevant.

I'd like to edit my post however it is not possible. Therefore I send longer post as reply.

I've noticed on my ADSL2+ circuit unsusual Hlog.

https://s22.postimg.cc/tgbw5782p/hlogwitoutmask.png

There are many undulations. I've written a lot about it on forum.kitz.co.uk. They suggestes perhaps I have got circuit consisting of many sections with different gauges. However as I know this type of circuit is very widespread but I don't see so unregular Hlog on other circuits.

I've done much progress towards explaining this Hlog however on forum.kitz.co.uk moderators forbidden to continue writing about my research results. Therefore I can't defend my ideas against their counter arguments.

https://forum.kitz.co.uk/index.php/topic,22097.0.html

https://forum.kitz.co.uk/index.php/topic,22114.0.html

I understand many people are not interested with my tenacious searching of answer but I think it is not reason to forbid me writing. Uninterested persons don't have to read my posts. Censorship is harm to potential interested person.



1. What was I explained?

I've discovered what causes through at tone ~55. It is caused by measurement errors. On the other circuit I've noticed small dip on the same tone.

https://s22.postimg.cc/pysdmc5qp/hlogdertyhwithmarke...

Furthermore, some day I had resynchronization and I and by mistake I was connected with target SNR margin 15 dB for donwstream and 17 db for upstream and other power output profile (18.9/12.4 dBm instead usual 18.6/12.1 dbM). By mistake because as I reconnected again I got again usual 6 dB SNR margin with usual power output. Then I had slightly more regular Hlog (weaker undulations).

https://s22.postimg.cc/uvdgu397l/hlog15db.png

This is a evidence of Hlog measurement errors (for example on tone ~55). It is noticable when I place two graphs on one coordinate system.

https://s22.postimg.cc/3ks5m6tg1/Double_Hlog2.png

One forum.kitz.co.uk user (burakkucat) has not agreed with my explanation. He emphasized limited accuracy of Hlog caused by granuality.

https://forum.kitz.co.uk/index.php/topic,22097.msg37...

However I think it weights in favour of my theory. Precisions limits cause that dip at ~110 tone is not noticable on other circuit Hlog. This Hlog have significantly smaller but the same measurement errors. Even my circuit had smaller than usual measurement errors at one day.

https://s22.postimg.cc/uvdgu397l/hlog15db.png

This is visible when I attach two graphs on one coordinate system.

https://s22.postimg.cc/3ks5m6tg1/Double_Hlog2.png

2. What haven't I explained yet?

I've still not disovered what causes tone ~210 dip. It is not smaller on anomalous synchronization with more accurate Hlog.

https://s22.postimg.cc/uvdgu397l/hlog15db.png

However one day I had event which would be helpful. I've noticed sudden reconnection and change of attenuation values at the time of pavement resurfacing works. It was 23.5/20.2 dB instead usual 25.0/14.9 dB (usual on D-Link DSL-2740B). Probably more users were reconnected because I had SNR margin about 4 dB immediately after reconnection (instead 6 dB). Next day after that day I also had reconnection during pavement resurfacing work and attenuation came back to usual values. On day with unusual attenuation day Hlog was significantly different per some tones. I think some shock caused some ipairtment on some joint reflected signal differently than usually.

https://s22.postimg.cc/rrzvo3ish/onedayhlog.png

Following there are usual and onedayhlog on one coordinate system.

https://s22.postimg.cc/rrzvo3ish/onedayhlog.png

I suspect dip moved from tone ~210 to tone ~150.

Other interesting observations which could help explain cause of dip is that as I've shortened cables in my home installation I've noticed that as I expected attenuation per the most of tones was reduced however on some tones attenuation increased.

1. Red graph is Hlog with 12m long cable connected to master socket. Green graph is Hlog with 1m long cable connected to master socket. Attenuation with 1m long cable was slightly lower per tones 33 to around 180. It was also lower per tones 200 to 400. However, it was slightly higher per tones 180 to 240 and on the end of graph.

https://s22.postimg.cc/8hsv5177l/doublehloglongshort...

2. Red graph is 1m long cable connected to master socket. Green graph is Hlog when I've cut down 20-30m cable from box to master socket and moved master socket. Attenuation on shorter circuit is slightly lower per tones 33 to 180 and per tones 350 to 511. However it is higher per tones 190 to 240 and per tones 280 to 320.

https://s22.postimg.cc/v6i24n6lt/doublehlogshortvery...

3. Red graph is Hlog with 12m long cable connected to master socket before cutting down. Green graph is circuit after cutting down 20-30 m cable to master socket. Attenuation on very short circuit is lower with exception per tones 180 to 240. On these tones is higher attenuation.

https://s22.postimg.cc/vknzhfq7l/doublehloglongverys...

It is interesting becuase it seems to me that longer cable does not cause signal is less attenuated on any tone than it was attenuated when cable is shorter. Perhaps my impairtment causing Hlog undulations is related with this unusual observation.

You posted a link to a pirate website which was removed and you were warned. You then posted it again. And that was just the latest oncident. You've caused a load of grief to the site admins and upset many of the other regular contributors to the Kite forums.

I cannot understand why you were not banned earlier!
