About this Manual
Introduction
The following summary will help you quickly locate the information you need in this User
Manual.
This introductory chapter contains a description of the product, its main features, components
and benefits.
Chapter 2; Installation and Antennas provides the basic installation guidelines, lists the
different antennas, cables and RF accessories, gives a description of the available antenna
sets, guides you in selecting the correct antenna or antenna set for specific applications,
explains how to align the antennas for optimal performance and how to synchronize two or
more co-located 2.048 Wireless modems units.
Chapter 3; Setup and Configuration explains how to access the system monitoring and
configuration functions, lists the statistical information, the system configuration parameters
and the various system diagnostic tests. All explanations refer to software version 1.7.
Chapter 4. Troubleshooting provides some useful troubleshooting tips.
Chapter 5. Technical Specifications lists system specifications of the 2.048Mbps Wireless
Modem and accessories.
Appendix A. V.35/RS-530/X.21 Applications contains a description of possible
configurations when connecting V.35/RS-530/ X.21 end equipment to the 2.048Mbps
Wireless Modem.
Appendix B. E1/T1 Applications describes ways to connect an E1/T1 2.048Mbps Wireless
Modem to E1/T1 end equipment.
Appendix C. Fractional E1/T1 Applications describes the relevant parameters for
Fractional E1/T1 applications, including the importance of using echo cancellation with voice
channels.
Appendix D. Installing Other Types of Receive Amplifiers provides tips on installation of
different types of receive amplifiers, which are supported by the 2.048Mbps Wireless Modem
but are not supplied by Black Box.
Note: This manual describes 2.048Mbps Wireless Modems with hardware version 2 that are
running software version 1.7. A 2.048Mbps Wireless Modem running software version 1.7
should be only used in links where the same software version is running on the other modemt.
It is not recommended to run software version 1.7 on hardware version 1, since many
features available in software version 1.7 are not supported. This includes support of
FractionalE1 and Fractional T1 LIUs, synchronization of collocated units and RSSI
measurement using a DVM.
