About Your 3Com U.S. Robotics ISDN Terminal
Adapter
This 3Com U.S. Robotics ISDN Terminal Adapter allows you to take
advantage of Integrated Services Digital Network, a much faster way to
connect to the Internet, corporate networks, or other online services. An
ISDN line can carry data, voice, and video transmissions at the same
time over a single line and support multiple devices on that line.
Accordingly, an ISDN line can be used for all of your communications
needs. Using your 3Com U.S. Robotics ISDN Terminal Adapter (ISDN
TA), you can make or receive regular telephone calls even while you
are connected to the Internet or another online service. And using other
analog devices, such as your fax machine, while you are online is just
as easy.
Not only are ISDN connections convenient, but they are also fast –
more than twice as fast as your analog modem connection. Your ISDN
TA transmits data at speeds of up to 128 Kbps with the highest
reliability and error-free performance possible. With compression and a
high-speed serial port, it can reach transmission speeds of up to 230.4
Kbps. And using USB, these speeds can be even higher.
