Preface: About This Guide

The purpose of this document is to provide information for
installing, operating, and testing the DEFINITY High Speed
Link.
Note: The DEFINITY High Speed Link will be referred to as the
''HSL'' throughout this guide.
This guide is written for technical people with a knowledge of
data communications hardware used in synchronous data
transfers. The reader should have an understanding of the V.35,
RS-366, and
EIA-232-D* interfaces.
Several type styles are used in this guide to represent information
presented on the front panel of the HSL. The following table
shows examples of the type styles used in this guide.
Slanted, block-style characters in all capital letters are
used for labels printed on the front panel of the HSL.
These labels are associated with the push buttons,
light emitting diodes (LEDs), and specific character
positions of the LCD message display.
Typewriter-style characters in all capital letters are
used for messages presented on the 16-character LCD
message display of the HSL. The system displays
multiple line messages one line at a time.
