George, I suspect that you would get a more complete answer to this on PPFORUM, where they support the MNP modems they sell. I can tell you that I had very noisy lines, with constant garbage instead of data, before I got this modem and got it set for MNP. I don't think I'm getting any speedup of transfer, since CIS is using MNP level4, and that level does not do the compression. I don't have noise problems any more, though. Once in a while, when the lines are at their worst, I get cut off, but I never see the garbage characters any more. If you can connect with another MNP Level 5 modem, you get data compression and that does give you nearly double (probably not quite) the rate, so that would be close to 4800. Currently, almost all of the CIS modems are at either 1200 or 2400. I believe they have done some testing with 9600 b, but that speed is not offered to us, so far as I know. ……Betty
