Hello everyone. I just purchased the Teltone ISDN simulator. I also purchased two Adran ACE NT-1. The ACE NT-1 came with striaght through rj-45 cables. I took the cables and connected one end to the Port 1 of the isdn simulator and the other side of the rj 45 connector to the back of the ACE NT-1 Network "U" port. I did the exact same thing for the other Port on the ISDN simulator as well as the ACE NT-1 I would like to know what do I set EACH of ACE NT1 Buses to. I have "Short" or "Long" for the configuration..and for Termination I see "None", "50", or "100" Currently I have both setup as Short and 50 for termination. The power and Error lights are fully enabled. The ready light flickers on and off every second. Both NT1 are doing this. Now I would like to know if this setup is correct? If so great...now on to the good part...how can I get two PC's to talk to each other utilizing these devices?? Do I connect NIC card in each pc and run a cable from on end into the NT1s? If anyone knows...please help. thank you for reading this rather long e-mail.
