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
