Well...I'm not exactly sure what you're talking about. If you've already got 1 working why don't you just set it up the same way as that one? From a dsp stand point I don't think you can specify more then 24 ports. But again....not real sure what you're doing over there in Argentina ;-) Todd -----Original Message----- From: usr-tc-admin@mailman.xmission.com [mailto:usr-tc-admin@mailman.xmission.com]On Behalf Of Intercom - Roberto Ravetti Sent: Tuesday, October 15, 2002 7:57 PM To: usr-tc@mailman.xmission.com Subject: [USR-TC] Hiper DSP NAC E1 Hi: I know that it is possible ( I have a Total working in that way), that I can add a USRobotics daugther card to a Hiper DSP NAC card T1, to work like a E1. That daugther card give the 6 extra modems. Someone know where I can buy that daugther card...? And if I buy a T1 card and the daugther card, what principal points I have in mind to make them works..?? Thanks in advance.
