Dialup modem transmission protocols and reates (client and server)

Does anybody know why when connecting two dial-up modems the maximum protocol you can use to stablish the communication is V.34 -33.6K?

I've read that you can connect with the server modems of the ISP using V.92 or V.90 and I would like to know if there is any explanation to this.

Thanks in advance.

Solution

  • V.92/V.90 requires one end of the link (in this case the ISP) to have digital access to the telephone network to work.

    Your two modems will be connecting in analogue and so can only support V.34 at most.
