DataTalker Owner’s Manual
2.1 Introduction
The Multi-Tech DataTalker is available in both desktop (DT10x) and rack-mount (DT10xR)
versions. The desktop version is designed for home office applications. It is mounted in a
horizontal cabinet and has an external power supply, a power switch, an originate switch, and a
switch that allows you to use it also as a stand-alone modem or terminal adapter. The rack-mount
version is designed for main office applications. It is mounted for vertical insertion into a Multi-
Tech RackTalker rack, has an internal power supply, is hot-swappable, and has a reset switch.
Otherwise, they are identical. DataTalkers are available with a synchronous or asynchronous
data channel, one or two voice/fax channels, and an optional internal composite link V.34
modem, 56K bps DSU, or 2B+D link ISDN terminal adapter.
