But then I tried connecting to our studio ftp server, and it started serving at 1500 kbps! This sustained for quite some time, not some caching effect. So, their international ports are probably slow. Again, their speeds seem to fluctuate. Tata Indicom's own test showed Your current download speed is: 695.50kbps
It was able to connect to our colinux machine, so no problems with ssh or rdp being blocked or anything like that. Latency-wise, it seemed even better than our leased line Tata internet port! 186 ms on pinging google.com, versus 256 ms with the leased line. Similar results to tracert as given here.
My tests were on Windows XP, so the built-in drivers could be used. The USB device has the drivers on in-built memory which is recognised as a CD drive. Autorun.exe and all that. For Linux, these people seem to have it worked out. Basically using wvdial, copy into /etc/wvdial.conf
[Dialer Defaults]
Modem = /dev/ttyUSB0
Init1 = ATZ
Phone = #777
Username = internet
Password = internet
New PPPD = yes
Stupid Mode = 1
then sudo wvdial
Edit: Some more info. The device gets a bit hot like a mobile phone during talk-time! Bittorrent speed tested with an Ubuntu CD download, was around 1.5 Mbps again. So, that seems to be the fastest it can deliver. Upload speeds were slightly slower - 800 kbps for the local ftp server. This product is a USB-based one, Tata also has a router configuration. Tariff is somewhat higher than BSNL's wireline ones.
