You can get almost as low latency on an ADSL connection in the right circumstances. I've seen down to 5ms on ADSL2+. Most people get nowhere near that though due to providers insistence on using interleaved mode.
That's interesting. I'm on FAST mode, my PING is usually around 50-60. I got in touch with my ISP (the one with bright future) to ask them to change to interleaved just to check if it improves the quality (not PING) of my line and was told they could NOT do it for me. Mind you - it took me almost 20 minutes to explain what I was after. I had to spell them 'interleaved', 'SNR' and so on. They had not a clue I was talking about. I heard them typing and probably googling and then was told to wait on hold until 'they speak to the supervisor about it'!! I even requested MAC code but still no luck. I dropped the whole idea eventually. I do appreciate my time after all... They don't
Sorry guys. I may be wrong saying that but I think this country suffers a LOT of inconvienence thanks to setting up call centres abroad (mainly in Asia I presume). That's one step too far...
I'm wondering if some other countries got to the same idea. For example Spain and call centres in Chile or Venezuela or Portugal and centres in Congo or Brazil...
