Thats right, there wasnt actually 40kbps being transferred literally but the hardware compression was able to acheive a good result on whatever this uncompressed data was and so reduced the amount of data needed to send so *effectively* u were getting 40kbps.
Kind of cool for some things. I prefer my 128k full duplex ADSL line which doesnt have hardware compression tho, but cuz its digital (no AD or DAC action going on).
And next year once I got a job I will get my 7.6Mbps ADSL line...... Counterstrike server on me! :-D :-D
