Could someone please help me with this doubt I have regarding how the Bit Rate gets decided for a network/link because for the maximum bit rate one needs to be aware of the channel/link bandwidth,right?So how does,say a MODEM/ or any transmitting device figure out the bandwidth of the link,based on which it can then fix the symbols,levels,bit rate etc.

Or is it that the Bit Rate is the charecteristic of the Modem and it is fixed hence we change the Cables/links accordingly or is it the other way, the bandwidth of the cables are fixed from which we calculate the maximum bit rate and get an apt MODEM?

I apologize if the question is lame as I am a beginner and this question was bugging me for a long time.

Thank you
