Just got an ISDN line installed. To be able to use the faster connection I know that I need to get my hands on an extra piece of kit. The manual I have says I need an 'ISDN modem'. I have been shopping online and have seen some ISDN modems. I have also come across ISDN terminal adaptors which desribe themselves as being used for connecting a pc to an ISDN line. Some of these TA's are cheaper than the products being advertised as modems. Can anyone educate me on this subject, specifically on whether a Terminal Adaptor will suffice as the interface between the ISDN control box and the PC.
