Dobrý den,
v několika předcházejících dnech došlo k navýšení rychlosti na naší ústředně, jde mi o to, že uživatel, který je na stejné lince jako já, bydlí o 100 metrů blíže k ústředně a je na stejných kabelech jako já má ADSL o rychlosti 10Mb/s a já mám stále 6Mb/s, níže přikládám log, myslíte, že by s tím šlo něco dělat, třeba nějak připojit napřímo?

Předem děkuji za odpověď, vyšší rychlost bych ocenil při stahování firemních materiálů pro každodení práci.

Podle mě máš velmi špatnou hodnotu "noise margin downstream", což je odstup signálu od šumu. Linku máš tak zašumělou, že by se ti mělo často rozpadávat spojení.
Tohle info mám pouze vyčtené, tzn. jsem obyč. teoretik, takže pokud plácám, tak nechť mě nějaký praktik opraví. :-D
Čerpal jsem odsud:
http://www.boards.ie/vbulletin/showthread.php?t=246697
konkrétně:
------------------------
Noise Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)
Relative strength of the DSL signal to Noise ratio. 6dB is the lowest dB manufactures specify for modem to be able to synch. In some instances interleaving can help raise the noise margin to an acceptable level. The higher the number the better for this measurement.
6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding
Line Attenuation
Measure of how much the signal has degraded between the DSLAM and the modem. Maximum signal loss recommendation is usually about 60dB. The lower the dB the better for this measurement.
20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues
Output Power
How much power modem (upstream) or DSLAM (downstream) is using. Maximum recommended is about 15dB. The lower the power the better for this measurement.
Danthare (7.6.2009 18:35:21)
Je to tak jak píšeš, šum není extrémní, ale pravděpodobně při kombinaci se vzdáleností od DSLAMu která bude vyšší než 1,5km to udělá ten výsledek který má na svých drátech...
skullik (7.6.2009 18:42:35)
A šlo by s tím něco udělat? Nechce se mi věřit že 100m dokáže takové divy, jak píši, kdyby daný uživatel nebyl napojený na stejných drátech, tak bych to ani neřešil.
skullik (7.6.2009 20:50:38)
Tak se mi hodnoty povedlo trochu zvýšit, zrácení kabelů a výměna switcheru.

Zdravím,
prosím co je to za log?Mám od O2 router DSL-584T,ale poslední dobou(po malování :o))) kdy jsem vše popřepojoval) mi děsně pomalu najíždějí stránky a kostičkuje se hodně O2 TV.Nevím čím to je,už jsem všechno 100x prolezl,vyměnil káble atd.,ale nemůžu na to přijít.Poradíte někdo jak zjistit problém?Jestli je to před routrem nebo za?Děkuji.
Marek (18.6.2009 12:46:22)
Hod sem data z modemu co ma nastaveno 10Mbit at muzem porovnavat.
Anonym (18.6.2009 14:38:03)
no dle toho vypisu mas na lince nastaveno 6M, ale rozjizdi se ti synchronizacni rychlost 8372/1160, co evidentne ukazuje na modem, zkus jeste prehrat fw nebo jeste zkusit jiny modem
Nargon (7.6.2009 20:13:24)
Ano v downu mas opravdu nizky margin. A podle tech hodnot tonu tam je neco shnileho. Tony 116 az 155 nejsou vubec vyuzity. To znamena ze je neco velice silne rusi. Pokud jsem to spocital spravne, meli by to byt frekvence 523KHz az 691KHz. A nevim co to zpusobuje. Ale neco na vedeni mezi modemem a ustrednou je spatnyho a zpusobuje to tenhle problem. Kdyby to tam nebylo tak bez problemu budes mit tech 10Mbit.
DSL (17.6.2009 22:45:43)
prostě chyba vedení, možná domovního, já už jsem předělal za FTP a mám 16Mbit, tak to chce kvalitní modem
