Hi Thanks,
It says: CONNECT 45333/V44. Why V44 and not V92?Is 45333/V44 good for a 56Kbps modem?
The bottom line is that 45333/V44 was the best available under the circumstances. During each modem connection establishment, the modems at either end of the telephone line negotiate a protocol that is both mutually supported and which is within the frequency response and noise characteristics of the connection. That's what all those bizarre noises are about at the beginning of the call. Even if you call the same number every time, you'll not usually get the same modem, at least not if you're calling an ISP POP (point of presence) where there may be hundreds of modems in a bank. Similarly, calling from the same number to the same POP will not always use the exact same equipment (except for the wire from your phone to the SLIC card at your central office, which is fixed, of course). So given all the variables involved, you will not always see the same speed and protocol selection even when you're calling the same POP over and over. As to why not V92, do you know that the modem (bank) you're calling actually supports it? Randall Schulz
