Hi.

Please explain to me why do we have to pay extra for higher ADSL access? I mean we use the same copper for 384 and up

You don’t pay for access on a toll road and they charge you extra to use the fast line, if you can afford the petrol you can go for it.

Cant Telkom just charge us for ADSL access and you sort out the speed with you ISP.

I would imagine you pay for the inherent traffic you put on the network. A user with a 10mbps connection will invariable cause higher congestion on the network than an 384kbps user. I guess you have to pay more for that privilege.

Sticking with your roads example I guess, someone that gets a speeding ticket for 140km/h will pay a little less than someone that gets one for 160km/h.

Think about it this way.
The internet, me talking about local now, is a network. (duh )
A network has capacity, ie a maximum bandwidth it can sustain.
So if everyone got 100Mbps connections then Telkom would have to upgrade their capacity in order to sustain all the traffic on the network.
So to cover those costs, they make us pay for the line speed we get

You might have the same copper telephone line to the DSLAM than the 10-24Mbps ADSL users, but like the other members said: the faster your ADSL connection, the more bandwidth Telkom will need to allocate/have for you on their links further upstream.

Like if they currently have 10x 384kbps users, then Telkom could get away with just say a 10Mbps connection from their exchange, but they'll need tonnes more bandwidth when they allow 10x 10Mbps ADSL users!

To add to this the 4 meg and higher is on the new IMAX DSLAM and will be on the MSANs soon so it is a continual upgrade.
old DSLAM Gdmt should have the one meg and 384 on them. and the newer DSLAMS the 4 meg and higher.
