Section 4 INSTALLATION & BASIC OPERATION
54
INTRODUCTION
This section offers a guide to the basic operation of the Zephyr in a format which is
mostly tutorial in style. As in
Quick Results, you are led through the steps which result in
a successful connection, but additional options are explored, and a more thorough
description of common functions and modes is given. We also provide some practical
advice on dealing with codec delay and other operational matters.
It is not, however, the ultimate resource. Other sections have more detailed information
on many topics:
•
Zephyr at a Glance (section 3) covers most user- level hardware questions;
connector pin- out, levels, and the like.
•
While this section covers in detail connecting to the Zephyr’s ISDN interface, ISDN
(section 5) explains what you need to know in order to order the line. The appendix
contains order forms to send to your telephone service provider.
•
Non- ISDN Networks (section 6) is for those who will be using Switched- 56 and
other types of non- ISDN data service.
•
Audio Coding Principles (section 7) helps you decide which method to use for a
given application.
•
Detailed Menu Reference (section 8) has thorough descriptions of each of the menu
items and modes. It is the best place to look for operating information and advice,
once you understand the basics and are ready to move on. This is the first place to
turn to for questions about compatibility and many other advanced issues.
•
All of the manual has information which can aid tracking down problems, but
Advanced Problem Solving (section 10) is specifically dedicated to this cause.
CONNECTING TO ISDN
The Zephyr’s internal ISDN interface is installed into the slot closest to the edge. This
module may have one or two modular jacks accessible through the rear panel opening,
depending upon whether it includes the integral NT1.
In Europe, the Telco always provides the NT1 and the ISDN ‘S’ interface will be used via
the 8 pin RJ- 45 jack, and the ISDN interface is provided only with this connection.
In the USA, a direct connection to the Telco "bare copper" is possible because of the
integral NT1.
