Sunt Ok acesti parametri?  :unsure:
Nu am decat de 8 luni ClickNet si nu ma pricep la "ei" (parametri).
Pot spuna ca sunt la circa 500-550 m de centrala.

Incearca alte modulatii.

@romeo_NT, Linksys WAG200G raporteaza SNR foarte ciudat, am vazut linie stabila si la SNR de 4dB cu WAG200!!!!! Speedtouch ST516v6, pe aceeasi linie, zicea 9dB!

@corleone_godfather
schimba modulatia pe ANSI T1.413! La atenuarea aia, nu merge bine pe ADSL2+.

am schimbat modulatia si mi se pare ca e cam aceeasi chestie , am mai incearcat si pe ADSL2 si scade cu 2 unitati atenuarea si creste putin SNR

Lasa modulatia care are SNR mare si atenuare mica. Deci ADSL2+ in cazul tau. Nu inteleg de ce, dar sunt cazuri si cazuri, este unde o duce mai bine pe ADSL2+, alteori pe ANSI T1.413.

Ia legatura cu RTC.



SNR mic pe download poate fi din cauza unor contacte imperfecte la mufe (praf, oxid etc); pentru upload SNRul depinde mai mult de conexiunile din centrala rtc, oricum linia este  "faina cu +"

eu zic ca sunt destul de buni parametrii acum , numai ca atenuarea aia e cam mare , voi ce ziceti?

Atenuarea e mare.
Dar,daca linia e stabila si ajungi la viteza pentru care ai semnat in contract,totul e ok.

Pt un modem TRENDNET TEW-435BRM exista vreun soft ce vizualizeaza parametrii liniei? (gen DMT)
In pagina de configurare NU se regasesc nicaieri.
De vreun an tot caut dar fara rezultat.

1. Start-run-cmd
2. telnet 192.168.1.254
3. User: Administrator
Parola:[daca ai parola, daca nu dai enter, lasi blank]
4. adsl config - vei vedea 3 chestii xdsltype, detect-lop si syslog
5. Acum schimbi xdsltype pe ADSL, ADSL2, ADSL2+ in felul urmator
adsl config xdsltype=ADSL
6. dai saveall
7. Acum modem-ul se restarteaza. Vezi caracteristicile liniei. Daca itzi convine lasi asa, daca nu schimbi pe ADSL2 sau ADSL2+
8. Daca ai probleme cu caderile de tensiune poti sa dezactivezi detect-lop: adsl config detect-lop=disabled.

Modulation: ANSI T1.413

Intrati cu telnet si tastati:

CODE
adsl config modemoption=00050000200000000000000000000000
saveall
exit

dupa care restartati modemul!

Vezi si tu , studiaza efectele! Daca nu-ti convin:
CODE
adsl config modemoption=00000000000000000000000000000000

pentru revenire


Incearca si pe alte modulatii, G992.1 G992.3 G992.5, vezi pe care ai atenuarea mai mica si SNR mai mare.

G992.1 = adsl config modemoption=0002000020
G992.2 = adsl config modemoption=0003000020
G992.5 = adsl config modemoption=0000000020
ANSI T1.413 = adsl config modemoption=0005000020
Default (auto-negociere) = adsl config modemoption=0000000000

Aici sunt parametrii Liniei : Attached File  Statistics.doc   64K   32 downloads

Acum un an , cand aveam banda de 8 Mb ,SNR-ul era 26 cu 30 , dupa ce am trecut la 20 Mb a scazut.
Oricum , vroiam sa va intreb care e treaba cu tipul INTERLEAVE ? E mai bine cu FAST ? Si cum se poate modifica ?
