He wanted to know if the DS3 was over-subscribed, and your response doesn't even reflect the question asked. What you are asking him to do only measures the T1 Link, not even to the DS3 yet. In fact, from the CSU/DSU, he could even be mux'd with a bunch of other T1's.
There really isn't a true way for the end user to tell what rate he is getting with any accuracy.
He would have to wait until the DS3 was full (maybe during peak hours), but the problem with this is that the rest of the internet is congested too, and therefore the speed from dslreports to the end user would not be accurate.
The other problem is, tests such as ftp test (which use 1500 byte packets), give results that have a huge variation. To get any good results you will have to use ftp a huge file (many many MB) so that the transfer can come to steady state.
The only true way to test this is really in a lab scenerio!
Ask the ISP how he gaurantees that the ds3 is not oversubscribed. Is it set up for Qos/Cos, and if so, how is it set up?
Good Luck!
The end user will never see this full 1.544 M. This is the rate at the receiver, which included Framing overhead. The actual end user can only see a 1.536 M.
