Interesting info from one of my ADSL routers.

Modem Status : Connected
DownStream Connection Speed : 640 kbps
UpStream Connection Speed : 384 kbps

Never seen anything like this before.
I wonder if it's the modem or Telkom that can't count?
 
Its usually

DownStream Connection Speed : 640 kbps
UpStream Connection Speed : 384 kbps

If your on the 512k package, and if ur on 384k, then ur just lucky :P

ya thats standard! - every1 like has that ive seen
 
so my modem says 320k down, my line speed is 192k down, but i only get a max download speed of 20KB/s which is 160kbps, so then WHAT THE HELL ARE THE DUMB @$@&$*@# DOING???
 
192k is the theoretical speed, u will never get that speed in reality.:( i donno about the whole 320 but got 192.... i got 384 but my router says 512...
 
Mmm. So I wonder if I can pay tillskim a "theoretical" amount for my connection - of course it will always only be about R29.99 per month...

hehe:rolleyes:

lol... but this is the standard, this is how it is around the world. UK,USA, China, Japan... all the same.
 
The reason Telkom sets the line speed at a higher rating than you are paying for is to make provision for any overheads and errors in the data transmission so as to ensure that you receive your approximate bandwidth rating. The overheads include MAC addresses, Header, Footers, Routing Information etc. all which use up bandwith but do not contribute to the 'data' you are receiving. If you go to http://www.adslguide.org.uk/tools/speedtest.asp(bottom of page) you will see that nobody in the UK gets their theoretical maximum.

As for people who achieve speeds that approximate an ADSL package that is higher than what they are paying for, this is probably due to their line distance to the exchange. The closer one is to the exchange, the closer one is going to get to ones theoretical maximum based on the settings that have been set for your line. The same logic applies for being further away.

Another variable to consider is that each exchange has their own techie managing the DSLAM which can contribute to variations in speed.

Hope this helps:p

Don't forget that ADSL also has a distance issue, so the increase is also to compensate those too far from the exchange.
 
Its just the physical line clocking of your local loop, between modem/router & DSLAM port. Service throughput (e.g. 192,384,512,1024 Kbps) speed regulated further downstream.
