zasto da se zakljuca.. Pa covek (vrhunski) raspolaze vrlo pouzadanim informacijama.. ne bi otvorio temu tek tako..Zakljucajte ovu temu dok ne bude pravih informacija
Prica se da ce izaci novi ADSL sa nekim jos vecim paketima ?
Ne bi se reklo.
Brži paketi ionako nisu ono što nam treba sada, već manje cene i bolje linije.
Slažem se.Mada bi još bolje bilo kada bi konačno omogućili ADSL u svim mestima u Srbiji i proširili kapacitete na postojećim centralama.Kada smanje cene i poboljšaju infrastrukturu, mogu da razmišljaju o ubrzanju.
meni je ugovor istekao septembra kad ono bese davno2008 godine mi jos istekao, i nit me ko zvao da produzim niti bilo sta, a internet i dalje imam
i placam

Zavisi sta ti pise u ugovoru. Ja sam raskinuo sa telekomom ,a nisam morao da vratim opremu.
Ne može...neće da radi...već probao davnih dana.. Matori DSLAM je kriv![]()
Već sam na Telekomu...ne verujem da će da može...podnosio sam zahtev za IPTV...i ništa se nije desilo...posle nekoliko meseci sam dobio mail da nema tehničkih mogućnosti ...loša parica![]()
Elem...ruter radi u G.DMT ...
SNR Margin (DB): Downstream:23.5 Upstream:31
Attenuation (dB): Downstream: 23.0 Upstream: 11.5
Output Power (dBm): Downstream: 19.8 Upstream: 11.9
Kad prebacim na ADSL2+ , nema ADSLa...
Kakve su ove vrednosti ?
p.s. pod PTT misliš na KDS? pošto, kolko sam upućen, nema slobodnih ADSL portova u ovom našem kraju... Ja sam u Omladinskih Brigada.. pored Perpera![]()
SNR or Signal to Noise Ratio:
Describes the ratio of usable data-signals on your line. You can associate the "signal" with the data traveling across your ADSL-line and the "noise" as the unwanted interference affecting the signal. The higher the number the better for this measurement. In some instances interleaving can help raise the noise margin to an acceptable level.
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 little or no synch problems
20dB-28dB is excellent
29dB or above is outstanding
If your SNR is below 12dB you are pretty much screwed and will not get a consistent level of ADSL-service. You could try to convince Telkom to rewire the cabling - but this is unlikely to happen.
Attenuation:
Is the reduction in signal strength on your phone line. In ADSL this may be reported as "loop loss" and is the natural deterioration of the ADSL signal over distance from the exchange. Attenuation is normally directly linked to the length of your line. Copper is traditionally used in the local loop and the higher gauge of copper will give the best signal, however some lines may have some aluminium or aluminium joints on the line which will increase resistance... as will oxidisation of joints. 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
The standard signal attenuation spread for a given speed is somewhere in the region of 25-30dB for ADSL1 speeds (if we had ADSL2/2+ this would be).
The following guide (distance vs. attenuation vs speed) gives you an guestimate what you can achieve:
<1km should be 23-24Mbit (nice speed, but doesn't it bug you that Telkom people walk through your bedroom?)
1.0km = 13.81dB = 23Mbit
1.5km = 20.7dB = 21Mbit
2.0km = 27.6dB = 18Mbit
2.5km = 34.5dB = 13Mbit
3.0km = 41.4dB = 8Mbit
3.5km = 48.3dB = 6Mbit
4.0km = 56dB = 4Mbit
4.5km = 62.1dB = 3Mbit
5.0km = 69dB = 2Mbit
>5.0km (you are pretty much poked --- sorry for you)
...Broj korisnika brzog pristupa internetu ADSL, ističe se u saopštenju, udvostručen je i iznosi 216.000, pošto je na kraju juna prošle goine Telekom Srbije imao 107.000 ADSL korisnika.
Ukupan broj ADSL korisnika u Srbiji, uključujući i druge internet provajdere, iznosi 326.450, saoštili su iz Telekoma Srbije...
Са овим предлозима у потпуности је сагласна и министарка Матић. Она, међутим, иде и корак даље и најављује да ће већ за месец и по дана бити учињен напредак када је реч о фиксној телефонији, која је и те како значајна за развој Интернета.
– Доделом лиценци у фиксној телефонији створићемо услове не само да Интернет буде бржи, већ и да кошта мање – каже за „Политику” Јасна Матић.
