Chapter One - INTRODUCTION
THE U-1496 SERIES UNIVERSAL MODEMS
The U-1496 series of high-speed modems feature five base models.
They are:
U-1496
External stand alone model with 20 x 2 LCD display and menu
control.
Also called U-1496S. Includes 2/4-wire leased line support.
U-1496E
External stand alone model with LED status indicators. 2-wire
application only.
U-1496B
PC internal card version.
U-1496R
Rack mount modem card version. Up to 16
U-1496Rs can be housed in
a RS-1600 rack with central panel control and 20 x 4 LCD display.
U-1496P
A portable model, particularly suitable for cellular data
communications.
There are also models with a plus (+) suffix, such as U-1496E+,
U-1496R+, and U-1496B+. These plus versions have a faster
processor and more memory space to support the ZyXEL 19200 bps
high-speed mode, advanced voice capability, and future updates
with more enhanced features.
The basic features, functions, and operation of the plus versions
are the same as those of the normal version. We do not
specifically mention the plus version in this manual unless there
are functional or operational differences. The U-1496 LCD model
is always a plus version.
