i still think it is all a bunch of crap, if they could not 'upgrade' all the 4mb users to 10mb they should have offered the 10mb as a new service and you can then upgrade if you want to. Now some people get the 'upgrade' while others get the run around when asking what is going to happen in your area. in the mean time pay the same as the guys getting the 10mb service, sux.
why not drop the 384 and start at 512, then 4mb and then 10mb.
i remember when i applied for my DSL Telkom said that they need to test my line to see what speed it can handle. with this 'upgrade' you don't get the choice and as far as i am aware G.DMT modulation can handle 12mb, which is what most of us use, so what is their prroblem.
At one point during the whole 'upgrade' process i had a download speed of 1mb/s, this lasted for about 30min. at that point i thought that i was part of the upgrade, when i got home in the evening it was back to normal. Called Telkom the next day and no one could tell me why that happened, one reason they gave was that the field tech guys were working on a problem in the area and that they may have had the lines opened for testing. so if i could do it then why not now, that so far no one can answer.
Yes it is a bit of sour grapes cause i experienced the added speed and had it taken away.
