DataTalker Owner’s Manual
1.1 Introduction
Congratulations! Your new Multi-Tech DataTalker™
is one of the finest data/voice/fax
concentrators on the market today. The DataTalker optimizes wide area network (WAN) links by
simultaneously transmitting voice and/or fax with LAN or computer data over a single phone line,
digital service, or ISDN service.
The DataTalker basic model (DT101) supports one asynchronous or synchronous input data
channel, one voice/fax channel, and a synchronous external composite link. Options include a
second voice/fax channel (DT102) and an internal composite link modem (DT101/V34 or DT102/
V34), DSU (DT101/56 or DT102/56), or ISDN terminal adapter (DT101/IS or DT102/IS). It comes
in two basic versions: a desktop version for home offices and a rack-mount version for central
office applications (DT101R and DT102R models). The DataTalker is software driven using
configuration menus, and is controlled by you through its command port for great flexibility and
ease of operation. This Owner’s Manual will help you to install and use your DataTalker, and also
serve as a valuable information resource in the future.

1.2 About This Manual
This manual has eight chapters. There are also several appendices at the end of the manual,
most of which summarize information contained in the chapters. These appendices can be used
as quick references. The information contained in each chapter is as follows:
Chapter 1 - Introduction
This chapter is an introduction to the world of multiplexing. If you already have an extensive
background in multiplexing, this introduction will provide a good review.
Chapter 2 - Configuration Examples
This chapter describes DataTalker configurations and provides examples of how the DataTalker
is typically used. The basic model has a synchronous or asynchronous data channel, a voice/fax
channel, and a composite link supporting synchronous communications. Options include a
second voice/fax channel and an internal V.34 (33.6K bps) modem, 56K bps DSU, or ISDN
terminal adapter.
Chapter 3 - Front and Back Panel Descriptions
Chapter 3 describes the front panel indicators, back panel connections, and switches. The front
panel indicators are grouped into data and command port, voice/fax channels, and composite link
status. The back panel provides all cable connections.
