I have heard that tapping high speed modems can be a little tricky because of the adaptive filtering done. The modems both have adaptive filters that adjust to the line as they see it. If you are tapping at some other point the filtering will not be optimimal for your case. I believe these filters take care of smearing and echos and things of that nature.

Dunno if this is how they did it, but you get *perfect* data tapping if you record digitally off the exchange trunks...
