Notes:  1) The U-1496, aka the U-1496S is no longer manufactured.
        2) Aside from nomenclature, the U-1496 is *exactly* the same as the 
           U-1496S; the U-1496+ is *exactly* the same as the U-1496S+.
        3) U-1496S/S+ models with ROMs v6.00 ROMs or newer can have a
           display screen that shows the lights that are on the E but not 
           the S.  Each "light" is depicted with a rectangular box and a
           corresponding short label.
        4) Rackmount modems require in addition, a RS-1600 Rack Mount System 
           and Network Management Software (NMS).
        5) All modems now ship with 14.4 ZyCellular capability.
