4 BASIC OPERATION & INSTALLATION
This section is intended only as an introduction. For many ISDN users, it will provide all the
information needed to get started with the unit. However, you may also need to review Section
5 (Guided Tour of the Menus) & Section 11 (Detailed Menu Reference), particularly if you are
using remote control or one of the other advanced features. If you are using V.35 or Ethernet
streaming mode see Section 10 and Appendix 6, respectively.
Section 7 also has a number of tips about SPIDs and ISDN protocol types. Section 1 has step‐by‐
step instructions for quick start up and initial testing.
4.1 Essentials
Your Zephyr Xstream should ideally be placed in a location convenient to the operator. As the
unit has no fan or other noise‐producing elements, you may wish to locate it in the studio to
which it is connected.
Large facilities may wish to locate a bank of Zephyr Xstreams in the main equipment room. In
this case a web browser can be used to control the Zephyr Xstream remotely using HTML. Or,
you may wish to consider using The Software Authority’s Zephyr Remote software package (see
http://www.softwareauthority.com/zephyrremote.htm for additional information).
Environmental Considerations
Heating, Ventilating, & Cooling Requirements
For optimal reliability, it is necessary to avoid exceeding the maximum allowable ambient air
temperatures surrounding the Zephyr Xstream. Ambient air temperature should be between 0
to 40 degrees Celsius (32 to 104 degrees Fahrenheit). Relative humidity may be between 0 to
98% (non‐condensing).
AC (mains) Requirements
The system is designed to work from 100 to 240 volts AC, 50‐60 Hz. As with any microprocessor‐
based equipment, it is desirable that the Zephyr Xstream be fed from a reliable source of clean
power. A UPS (uninterruptible power supply) with noise suppression would be helpful,
particularly if local power is unreliable.
AC surge protection is also desirable. Our first choice would be a top‐of‐the‐line unit containing
a ferro‐resonant transformer as well as a UPS. You will want to avoid "bargain basement"
brands, which can cause more problems than they solve.
One possible source is Best Power Technology with its ferro‐resonant transformer/UPS
combination for extremely clean UPS power. Another source is American Power Conversion.
Their Back‐Ups Pro series is well suited for microprocessor‐based equipment such as the Zephyr
Xstream.
Be sure that UPS battery replacement goes on your preventative maintenance schedule.
