Greetings, I just wanted to warn people who intend to use TwoStateErrorModel and its derivatives. Note that the transitionState() function of this class upperbounds the duration of state_1 with 120 seconds. This is done in errmodel.cc in ns v2.30. I do not know the reason behind this upperlimit, but if I am not mistaken, this upperbound makes it pointless to assign an average duration to state_1 at the time this class is instantiated. I would be happy to hear what others think. Regards, Guray
