Telkom SHDSL release date?

yup that 512... not quite the full 512 ... cause theoratically we should be getting 512/8=64kbs ...

Thanks you've cleared that up. Now I understand why 356 is best option at present.

adsl limits are 8meg ... adsl2 can go up to 24meg (i think). depends on how far you from the exchange though ( i might be wrong with those limits). and ADSL+ allowed for greater distance from the exchange ( i might be wrong with all of this ... memory is failing me)

ADSL2 can go upto 12Mbps while ADSL2+ goes upto 24Mbps

2) How many FIRST WORLD COUNTRIES (if any other countries) have at some stage enabled this?

I wouldnt know exactly how many countries have implemented SHDSL, but I do know that BT in the UK offers SHDSL, or SDSL as its called in Europe: http://www.btbroadbandoffice.com/broadband/sdsl

None of this technology will help us normal residential users a bit for as long as bandwidth prices are controlled by Telkom

see you can order straight shdsl from telkom and it has been available for some time now, but the bigger coporates buy it... it is a 2mb link costing around R20 000 plus a month! that is 2mb up and 2mb down! i have since heard this new talk of adsl via shdsl, i think they basically take that 2mb link and configure on the atm side a 1meg container, for down and whatever the up link is say 256kbit... for adsl 1024 ... thats just what i think

and also for 99% of users, having a high uplink rate is not going to benefit them thats why adsl is there ...

The world is changing, that might have been true a few years back when consumers were not content providers themselves. Now days with video conferencing, skype, people running game servers and other similar technologies it is useful to be able to send data faster.

If you could use your entire linespeed for downloading you would, but the Internet is built on protocols, the "missing" bandwidth goes towards protocol overhead. As a rule of thumb you can expect a maximum of about 90% of your true linespeed.

192kbps / 8 = 24 kB/s * 0.9 = 22kB/s
384kbps / 8 = 48 * 0.9 = 43kB/s
512kbps / 8 = 64 * 0.9 = 58kB/s
1024kbps / 8 = 128 * 0.9 = 115kB/s

Telkom's system is screwed up though. It seems common for 192 users to get 384 speeds and for 384 users to get near 512 speeds. I pull > 40kB/s from my 192 most of the time.
