Can X2 modems accept 56k connections from Rockwell >and Motorola (assuming them to be the 3rd player) modems? I believe the only way to be able to handle X2 is with the USR Total Control RACK... They have not licensed their code to anyone else... The way the X2 and K.Flex standards work (which are not at all interoperable), is that the receving end of the call must be some PRI type solution... For the technologies to work, there must only be ONE analog to digital conversion in the virtual circut between ends...i.e. an X2 home cant dial another X2 home and get 53K.... ---Mike ********************************************************************** Mike Tancsa (mike@sentex.net) * To do is to be -- Nietzsche Sentex Communications Corp, * To be is to do -- Sartre Cambridge, Ontario * Do be do be do -- Sinatra (http://www.sentex.net/~mdtancsa) *
