1.1 Overview of the MISTRAL USB
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 33.6Kbps (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 ISDN devices implemented throughout the world, a
truly digital network will emerge, allowing everyone fast and
easy access to the global information highway.
What is USB?
USB is an abbreviation for Universal Serial Bus. It is a new
peripheral bus employing a single connector type for all low-
speed 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
