Introduction
DS1000/2000 Basics
The DS1000 and DS2000 use 32-bit architecture to provide Digital Signal Pro-
cessor (DSP) technology, on-board flash memory and field software upgradeabil-

Update Utility in combination with a CD containing the system software. The
DS2000 uses a PC card containing the system software to upgrade software.
The compact DS1000 starts with 3 lines, 8 stations and 4 analog ports. It expands
to 6 lines, 16 stations, and 8 analog ports just by plugging in a single expansion
