Re: Q] packet error rate

Hi !

I don't have the answer to your question! but I was trying to use twostate
error model and ran into some trouble.. could you please let me know the
way you are using the error model, i.e. how you have specified in the tcl
script the error means and the link on which the error occurs ..
