Introduction
1.1 An Overview of the tiny USB ISDN
TA 128
1.1.1 What is ISDN?
ISDN is an abbreviation for Integrated Services Digital Network.
ISDN transfers information digitally and integrates all
telecommunication services (such as telephone, teletext,
videotex, etc.) into a single network. Using ISDN, you can
transfer text, voice, data files, images, and even video.
Before the use of ISDN, telecommunications operated using
analog devices, which limited the quality of telecommunication
transfers. With ISDN technology, the telephone lines can
transmit data digitally with much greater speed and clarity of
transmission than with analog transmissions. The ISDN is
capable of transmitting all kinds of information at greatly
accelerated rates. A typical modem transmission has a rate of
56Kbps (kilobits per second or thousand bits per second). ISDN
digital technology allows transfer rates of up to 128Kbps.
Because ISDN transmits data digitally, the data is virtually error
free, and the transmission is much clearer, with fewer
interruptions and slowdowns in facsimile transmissions. With
1
tiny USB ISDN TA128
ISDN devices implemented throughout the world, a truly digital
network will emerge, allowing everyone fast and easy access to
the global information highway.
1.1.2 What is USB?
USB is an abbreviation for Universal Serial Bus. It is a new
peripheral bus employing a single connector type for all lowspeed and medium-speed devices, such as keyboard, mouse,
monitor, floppy drive, printer, scanner, digital camera, modem
and ISDN TA. It brings plug-and-play of computer peripherals
outside the box, eliminating the need to install cards into
dedicated computer slots and reconfigure the system. PCs
equipped with USB allow computer peripherals to be
automatically configured as soon as they are hot attached,
without the need to reboot. USB also allows multiple devices,
up to 127, to run simultaneously on a computer; some
peripherals, such as monitors and keyboards, can act as
additional plug-in hubs to make it easy for users to manage
peripherals on the desktop. USB does offer unprecedented
peripheral expandability and ease of use for PC users.
With better throughput of 12Mbps (megabits per second or
million bits per second), USB is expected to rapidly become the
preferred means of connecting ISDN TAs, though it will not
replace the traditional PC ports (COM and LPT) overnight.
1.1.3 The tiny USB ISDN TA 128
The tiny USB ISDN TA 128 is ideally suited to give your PC
2
access to the world of the Integrated Services Digital Network.
It is easy to install, and easy to configure because it is fully
plug-and-play compatible. The Windows 98, Me, 2000 or XP
operating systems will automatically install and configure the
tiny USB ISDN TA 128.
With the tiny USB ISDN TA 128, you can have an ISDN
telephone, answering machine, file transfer, videotex, G3/G4
Fax functions, and Internet access. This will bring you more
versatility and efficiency in the ISDN era.
