No, no, and no. There is nothing that says *really* what the upload is supposed to be, and 1/4 of the speed on common
ADSL profiles is technologically impossible, especially on plans beyond 4mbit/s...
Yes, while the ADSL2+ M Annex specification does allow for up to 3.5mbit/s upload, in most countries where full-speed ADSL is available the max upload speed you can get is 1mbit/s on a line that is up to 24mbit/s download speed - but even if India was using the latest an greatest DSL specifications, 3.5/24 is still only about 1/7 the potential speed.
Of course, I am talking mostly about DSL since it is the technology in use by near as makes no difference 90% of the Indian market.
Typically speaking, your upload speed is likely to be 256 or 512k depending on your plan, and some ISPs (MTNL from memory) allow you to pay for more for higher upload speeds. The upload speeds you can achieve on other ISPs mostly depends on what technology they have in use - those of us on Metro-Ethernet style connections can usually get near-synchronous multi-megabit speeds if the plan so allows.
Ah, thanks for the corrections
Why would 3.5/24 be only 1/7 of the potential speed ?
Also, I remember reading on this forum, some time ago, that isps were required to keep upload at atleast 1/4 of download, perhaps that particular post was incorrect, or my memory has faded
