What are the differences between the Internal Cards and the TA?

All of the products offer similar features and applications. The big difference is that the cards fit inside your computer, while the TA sits on the desktop and simply connects to an available serial port on your PC. The PCI & PCMCIA Cards offer the best data transmission speeds as they connect directly to the internal bus of your PC. Therefore while the TA may be more suitable for the novice PC user or net surfer, its speed may be slightly limited by the capability of your PC's serial port. All products, however, come with an ample 6m ISDN line cable, which means that you don't necessarily have to position your PC next to your ISDN or Highway wall socket.
