Hello,

around the problem with the too highly computed power-CUT-bake zuverifizieren far, would be grateful I over a few line data. I want to then argue with Telefonica over it.

I am at line data interest the one absorption of up to 17 railways have, either directly as screen SHOT of the FRITZ! Box or a screen provides also OrbMT(which the UFO to select can).

An exact explanation to the problem finds it here.
Hello Joxxer,

that find I to super an idea.
Since then I a 1&1 complete connection have, am with me also the problem with the PCB.

Perhaps you reach something with your action.

Greeting
Stegi
Hello,

there I do not want to stand back. I have however since some firmware versions no more problem with power-CUT-bake. In former times it was with 5/1, the interconnect capacitance therefore approx. 2 MBit/s lower.
@Frank: You wear however strongly this screw turned…

Thus strongly the indicated SNR sinks - with 2 railways you could have never scarcely 16 MBit.

more @Joxxer: You have my Screenshots already…
Hello,

but the box is stable thereby - before the last firmware update the DSL Sync held 78 days.
With me it looks in such a way, times something at the attitudes turned.
Hello.

@ sven@mainz,

you are affected with Arcor and not by the problem. The problem arises usually only in the turning ducks DSLAMs with Centillum COE von Huawei. Therefore I need only pictures away and over Telefonica am tied up.

@ frank_m24

Your line does not show somewhere with 17 railways the haven begins the PCB any longer so wrongly zuberechnen whereby also only since some months and/or 1 year like that is. It does not arise with some Carriern the problem as strongly as with Telefonica, which probably points on revised profile attitudes.
Hello,

I do not know myself in the subject so well out. Perhaps but my pictures help. I have anyhow a Telefonica 1und1 complete connection with 16 railways.

Greeting
Smithy
Such a few Neugikeiten. I got about 150 MT a large manual today from Huawei to the DSLAM series. There I will read myself. Do not power-CUT-bake problem is well-known with those in the form, the transmitting power can either adaptive be negotiated in the ADSL2+ mode.
A E-Mail at Telefonica is so far unanswered. I would be further grateful over further line data.
Perhaps the reading helps me. I have again tried directly with CO2 to come through, there was the answer thus you have problems with your W-Lan.

Update: Definitv does not give it power-CUT-bakes with ADSL profiles, with ADSL2+ profiles can it give a this by given the PSD value organizations is calculated, thus from given the transmitting powers. I have in one contribute times a picture angehangen where the line one measured, the measurement calls itself SELT measurement. There with a not changed profile (adjusted from work) one measures, why power-CUT-bake then also correctly computed, what really the assumption arise lets, which is it a profile attitude thing.

Fr. 29.01.
Update:
I have now so far the guidance through, meanwhile believes to 99% which one “extendend the profile attitudes” no more did not change and therefore the problem is simply also so alike up to certain absorptions. Because which is also merry, with the Broadcom Linecards, one has also the profile no longer so adjusted that the amateur radio gaps in the spectrum to be faded out is but there one has the complete spectrum available. Which like that with the CTL Linecards also no problem would be.
I know me not yet completely erkren why by the PSD Table the transmitting power am so extremely throttled, because with other Providern is not handled so extreme only at all, and/or. with the Broadcom Linecards in the Huaweis also not. But it is actually no nose in power-CUT-bakes separates a result profile attitudes out completely become outdated.
I do not believe also few sinvollen optimizations a those times as much time would take up, would not be so bad the Centillium Linecards at all. Naja I wait times starting from which answers Telefonica. My error was which I, because those FRITZ! Box so a high PCB indicated, from it the problem derived, which however in the case irsinn was. I think times the Fritz box interpret this small transmitting power only as PCB, which would also not explain why the PCB be changed manually downward can. Since the PCB does not behave also so typically guess adaptive which it would have but usually with negotiate remains fixed.

CO2 does not see action need of haven, it is so far everything correct, one became now the range down-sets in my case, because during an absorption of 10,6 railways are never 16000 possible. The term power-CUT-bake or with the transmitting power could the nothing begin.

It in it persisted that maximally only possible is, which is indicated as interconnect capacitance. Only this value by the zuniedrige transmitting power also as too low is not indicated was then up once any longer correct and important. I did not keep an answer of Telefonica direct yet.

So before one subordinates to me, I have nix against CO2 am a fair Provider and/or. that is always very friendly Kundenservice. Me it goes only solving and no Anbieterbashing zubetreiben the problem from the technical side in this Thread therefore herzu.
Thus, also of me bissl assistance:
The first picture is of more ner 7170, normal line
Afterwards the 7270, normal line
The latter is the 7270 with 2x100 ohms of resistances BEFORE the TAE in the line. (set with SNR now on -1 max. sync).
Pleasant side effect: CRCs and FECs down-went drastically, degree times to 5000 FECs and 26 (!) CRCs after 5 hours. In former times I had FEC within the range of five figures after 1 hour already. And all this, because the absorption of 8 to 13 up-went.
I attempt Fastpath to still turn on shortly, but I doubt that so well will work.
So unfortunately I so far still no answer of Telefonica got, with me the haven in the meantime of 6 to 8 and now 16 Mbit one had changed directly. I have times with a Onlineshop a ISDN conclusion clutch (100ohm) procured (I have two left fingers with soldering irons), these reduced with me power-CUT-bake around 5 railways.

I hope I get nevertheless still another answer of those.
I made a while ago a surprising statement: Broadcom haven synct also on the 6000er-Profil (without Speedping and without Powerupload) only with 6572 kbit/s in the Downstream, and not with 6781 kbit/s. My absorption is with approximately 35 railways in the Downstream; Interconnect capacitance however with scarcely 11000 kbit/s in the Downstream.

That suggests that the profiles are wrongly configured, and it not to power-CUT-bake and is appropriate for Centillium, otherwise it would not like that be with Broadcom.
Unfortunate the Telefonica also no need sees the profiles revising times.
Thus according to Huawei definitv no error lies to the Linecard, it gave times problems some increased PCB caused, but these are already for one and a half years no longer available, gave probably times a Bugfixing, to what extent that was not taken over leaves itself naturally to determine. But had to be made probably a few extended attitudes on the DSLAM, which was probably never made so far.

Unfortunately I from Telefonica no answer received. The simplest solution is probably really the reconditions of the line artificially zuerhhen. The problem steps also independently of the CPE in the modem or routs, all the same whether Broadcom, TI, Lantiq, Realtek or trend chip (there it leaves however as previously mentioned, by autoexec.net modding goes around oneself).

Actually admit a tragedy of the offerers not even briefly, a feedback, since this Linecards is nevertheless quite frequent in Germany in use.
After I freshly transferred to the Fritz box, purely informatively my line data:

Switching center:
Centillium
0.0 - H1 2
B50043454E54
2310
0000B520
Tonight there were updates with my haven nen:
PCB is now on 0db.
But looks, the Linecard spits now also ne version number out!
Since today I have full Sync with the Standard-6000-Profil also finally at a Broadcom haven.

CO2 seems to have geupdatet tonight all DSLAM's.
I believe that to Telefonica far made, thus also for Whosale customer such as 1und1.
Aha… perhaps is also the reason for my Line improvement. PCB of 10 to 3! Interconnect capacitance of 12 to 18 MBit.

DSL haven shows now (no memory, whether here which changed was anyhow always Centillium):
Code:
Centillium 
16,189 - H1 12
 B50043454E54 
2310 
0000BD

What is indicated now with you with DSL haven?

----
Supplement

Ok one with you was then driven also the update, which repairs finally the power CUT baking computation. Why you have then also more range in the Download.
Also that is again out-spat the CTL now ne version number.
Hello,

does the problem exist with my connection still? Is there still which in it? I do not understand the difference between the current and the max data rate. With one of 16 connection should go nevertheless upward. Or not?

My values are down.

Greeting
Christoph
No you do not have the problem also more, have none more with Telefonica more…
Which you to make know are the signal-to-noise ratio down-set…
OK ONE. Thanks. Signal-to-noise ratio down-set could thus help. Goes along this guidance? Property times -90 registered, but the distance only goes down on 9. After I reset the values (on 0 like before) was even still a little worse the connection. The whole Threat also read and all three values later to -90 set, without large change. Which I could still make and/or. in which contribution can I read myself in?

Thanks

Christoph
Hello,

if the DSLAM does not permit it, then you cannot make anything.
Hello,

thanks for the answer. Harm.

I thought if I 14056/766 get
and the capacity 16128/808 and/or.
MaxDSLAM 17728/768 is indicated is there still which in it.

Meant do not permit that which one throttled?

Greeting
Christoph

HP.: If we too offtopic will please cut off now and as new contribution will resume.
Hello,

no, you are not throttled. As a function of the line parameters those can give a larger target signal-to-noise ratio to carrier. Thus the stability of the line, the Sync speed increases however unfortunately reduces. With you 9 seems - 10 railways as a goal to be adjusted. The Fritz box can one DSLAM inquire whether is possible for the one reduction of the signal-to-noise ratio, but it does not have to accept that.

Throttles became one you over the “maximum DSLAM data rate”. But those is to the highest value, which is possible.
Is correct if I there which forgot, with the normal CO2 DSL 16000 profile, the signal-to-noise ratio cannot be down-set, you would have in addition Speedping (Fastpath) and Powerupload in addition to book, then the haven permits also that to lower the SNR.
I know something Offtopic here, but since it indirectly which with the Centillium update to do has….

As one in the appendix to see can has I a higher Sync in the Upload than the max. Interconnect capacitance as per. Fritz box. Likewise my line loss went in the Upload from 29 railways to 21 railways down. Whether I that times in such a way to believe may?!?!?
Rear one is correctly that the absorption down goes in the Upload, this is now correctly indicated. Before the update you always zuhoch one indicated.

Is with the Upload after a Neusync like that, looks as more htter rout with a SNR of 5 railways in the Upload syncronisiert, which interconnect capacitance computed with the profile with a SNR of 6 railways.
Rear one more joxxer,

it, I naturally started again caution for the sake of the frit also times and made still natrgliche various Resyncs. Also times DSL just looked at, each times the same from Fun of the nen Recovery of the box made and times without further data me. Since that runs DSL stable, it really does not disturb me….
Naja if it stably runs . But since the update the Linecards runs eh very well.
I can confirm that definitely!!!!! However the spectrum really improved with me. There I must ausprechen Telefonica also times praise. Noticed I also that the LOT with the COE became likewise less.
Hmm however HEC error you have nevertheless still ne quantity, me were not at all in such a way noticeable.
I was up to 19.02. on 16 MBit throttled. Up to 16. (?) I had an interconnect capacitance of 18 MBit. Then it corresponded to the above mentioned suddenly. Restriction. At the deadline the restriction was waived then and schwups is both on 18 Mbit?!

HP: See. Diagram of even (see below) with of 15. (see here). Of 16. - 19. I have unfortunately no screen SHOT.
Hello,

with me tonight the changed DSLAM Konfig was brought in.
Is finite power-CUT-bake on zero and the speed went strongly upward.
The Fritz box synchronizes even more highly than in former times to Telekom the DSLAM.

Greeting
Stegi
Also at my DSLAM last night was updated, the line became obviously thereby clearly more stable. The connecting speeds increased in both directions, the errors became less. And although at my haven never power-CUT-bake errors was.

But times, perhaps one still another little sees at can screw the line values…

Greeting
Sandra
Hello,

with me at the last night an update of the line was likewise made. The Centillium introduces itself now perfectly, also the speed rose clearly. Both in the down and in the Upload.

Here my old line data: Left

In the appendix my new.

Thank you at more joxxer, which was perhaps not completely innocent to the fact that the updates were made.

Greeting
smithy
Hmm… that something would not have changed in my line, but the DSLAM does not spit Versionsnr now. more out? There only “Centillium, 16,189 - H1 12, 00, 00, 00” had before 26h nen power failure and since stands.
That is normal after a Neusyncronisation of the line should that stsehen again there. It gives the version number nevertheless from 16.189.

@Smithy I do not believe it which with me to do had, which one nen updates had driven. Because also the Broadcom Linecards was geupdatet.
Me would interest, in which places CO2 Telefnica already made the DSL to updates.

With me in Munich it is the case, in Stuttgart however still no updates was brought in anyhow.
Hagen also already got the update.
Victories also…
@rentek

With me update was also carried out. I am in the area Stuttgart (Nrtingen)

Greeting
Smithy
does the update come also to Augsburg? or is there only certain places? Have nen power-CUT-bake from 4
mfg
Around the topic again to respond I have also a question, my line values look nevertheless rather good, nevertheless reach I with the 7170 not the full Sync.

There does someone have Tipps for me? Should I on the letze laboratory with the attitude possibilities down degrees?

Screen enclosed:


Thanks and greeting
The power CUT baking error is not present here, the DSLAM has already the newer firmware.
Little range is lost through the carriers faded out by the Provider, to it can you however nothing change.

The 2db power-CUT-bake are for the line loss in the framework, which is noticeable however, is that your line with the higher frequencies despite the small line absorption (and thus length) quite strongly breaks in.

Your house wiring is etc. in order?

Otherwise still the high SNRM falls in downstream on although the max. adjusted range is not yet reached, perhaps the Provider a target SNRM of 9db or 10db stopped.

Screw times the target SNRM down and/or tries times another modem (if you still one “fly around” have).
Thanks for your answer!

The cables completely again shifted of the TAE into the cellar.

VST is approx. 150 meters of air line away which naturally necessarily the cable length to be does not have.

I have still another Siemens SL2 and a Speedtouch 585i rumfliegen and these the days will times test.

However without a 2tes wanted to use the comfort of the FB equipment to operate.
If the cables and the TAE are new can you probably nothing else optimize at the wiring (anyhow not without disproportionate expenditure).

Try times the Speedtouch and poste the values here. The DSL part of the Speedtouchs is rather not good quite, the remainder.

Best you take the Speedtouch as pure DSL modem and leave PPPoE a choice, VoIP, WLAN, etc. settle by the Fritz box.
I do not make the days I yet drew in there times there kanns still which last.

Wanted to save me however 2 devices.
yo steve. Eifnach the SNR around -4 railways, dannn you put back yours vollsync in downlodd are gotten

Downloaden here simply the Fritz box editor from the forum and afterwards the Firtzbox with the Tool select. Then the entry DownstreamMarginOffset look for, besides you find one number (0). This number replaces you by -40.Wenn you then still no Vollsync have kannste you the number eifnach up to -60 to down-screw


greet
Hello,

if it has still another so old firmware, which an error in power-CUT-bake computed, then that does not function. And if the offerer a target specified SNR, also not.

The problem is however obviously not power-CUT-bakes, but the strong waste in the spectrum within the upper range here. There it applies to set. Otherwise one fights symptoms, but not causes, and returns. One may not forget that one makes the line substantially more unstable by reduction of the SNR. It concerns 7170, not around 7270. The 7170 does not get along so easily with so little SNR.
Thus I times the laboratory firmware draufgemacht and the SNR -2 set these amounts to now still 8-9 railways and the Sync is up-to-date 18107 Kbits see:


Max. one. DSL to data rate kBit/s 18112 1152
Min. DSL to data rate kBit/s 256 256
Interconnect capacitance kBit/s 18160 1048
Current data rate kBit/s 18107 1014

Latency 7 ms 8 ms
Bitswap on out
Seamless rate adaptation out out
Impulses Noise Protection 0.6 1.2
L2 power mode WELL - -

Signal/signal-to-noise ratio railways 9 9
Line loss railways 8 6
Power-CUT-bake railways 2 0


Has itself in any case been worth line is stable since 2 to meet without large errors…

Only again feedback wanted to give!

Greeting

HP: To the topic symptoms fight it lie against my dwelling in EEC into the cellar the maximum of 5 meters of cables of this already as mentioned above completely renew inclusive Telephone box of the T-Com. What please is one to there still fight?
