Upload speed should be 1/8th of your download speed. But this will never happen. I doubt anyone has upload speeds reaching even 1 mbps in bsnl
adsl broadband. Cant blame them really, the line quality will take a massive hit if they increase the upload speed.
About a year back when bsnl increased download speeds, I forced my JE to increase my upload speed to 1 mbps (was using a 8 mbps download plan) from about 400 kbps. He did it and then I faced constant disconnections in my line. When they reduced the upload speed, the internet became very stable. That was a lesson learnt.
Now i've shifted to a different location and am using 249 plan. The speeds are supposed to be 8 mbps download in this plan, but i get 12.5 mbps download and 600 kbps download.
Rate Down stream: 12495 kbps
Rate up stream : 621 kbps
Bottom line, your upload and download speed depends on the distance from the exchange, line quality and your luck.
