color:#1F497D'>NGN is simply FTTC (Fiber to the Curb). At the curb, they put
in a DSLAM that converts the fiber to ADSL2+ or VDSL. ADSL2+ is already active
on 8mb connections; most of the modems they have been passing out in the last
few years are ADSL2+ compatible. ADSL2+ has a maximum of 24mb down / 1.4mb up
(theoretically in ideal line conditions). Since they can't guarantee perfect
line conditions (and upload is more sensitive to attenuation), they cap it at
800mb up. Eventually, when they want to go above these limits to their "up
to 50mb download speeds" they are advertising, you will have to change out
your modem for VDSL or VDSL2. VDSL modems can handle up to 100mb upstream as
well, so that will be when you see better upload performance. <o:p></o:p></span></p>

Not only they have no Symmetric packages offered on their website for the NGN
world, all their Asymmetric packages still have ridiculous upstream bandwidth
as ever. For example 30Mbit/s down with... 1Mbit/s up. Sometimes I even wonder
if this upstream is fast enough to sustain all the TCP ACKs for a 30Mbit/s
download :(<br>
<br>
Of course, I doubt this is an NGN limitation. If we would have a FiOS[1]
equivalent bandwidth, like 50Mbit/s down and 20Mbit/s up... how could they sell
a lousy 2Mbit/s up/down E1 for thousands of shekels every month?<br>
