Here I offer some starter information about the equipment you need to get hooked up and introduce you to some of the obtuse terminology you'll need to know to order your own ISDN line. So you need special equipment that sends and receives digital ISDN signals. ISDN terminal adapters are the interfaces you use to communicate over the ISDN line, and they include ISDN telephones, videoconferencing systems, and digital modems. There are many different kinds of terminal adapters. To connect your ISDN terminal adapters to your ISDN line, you have to plug them into an NT-1.
