interruptions.
This document assumes the technician/engineer understands the basic principles and functionality involved
with repeater and in-building systems. It is geared to the practical concerns of the installer.
Application
This guide should be applied whenever a need exists to add digital repeater capability to an existing system or when this
capability is being included with a new installation.
Document Organization
This manual includes the following chapters:
Chapter 1: Product Overview – Provides an Overview of the DSP85 Original Series plus Modular 250 and 251 Series
Chapter 2: System Optimization Installation Tips – Provides information for optimization of using the system
Chapter 3: Web-Based GUI – Provides information on using the system through a web-based graphical user interface
Chapter 4: Console Interface – Provides information on local access to the repeater through console interface
Appendix A: Attenuation and Dynamic Range Guidelines – Provides information on attenuation and dynamic range
guidelines
Appendix B: Band Plans and Filter File Naming Conventions – Provides information on the band plans and filter file
naming conventions

Safety Guidelines
The general safety information in this guideline applies to both operating and service personnel. Specific warnings and
cautions will be found in other parts of this manual where they apply, but may not appear in this summary. Failure to comply
with these precautions or specific warnings elsewhere in the manual violates safety standards of design, manufacture, and
intended use of equipment. Westell Technologies assumes no liability for the customer’s failure to comply with these
requirements:
Grounding: This digital repeater system is designed to operate from 100 - 240 VAC and should always be operated with
the
ground wire properly connected. Do not remove or otherwise alter the grounding lug on the power cord.
Explosive atmospheres: To avoid explosion or fire, do not operate this product in the presence of flammable gases or
fumes.
Lightning danger: Do not install or make adjustments to this unit during an electrical storm. Use of a suitable lightning
arrester, such
as Westell Technologies CSI-CAP, is strongly recommended.
No user
serviceable parts inside. Hazardous voltages are present when the cover is removed. Opening the chassis will
void your
warranty. If you suspect a malfunction with this product, call your dealer or Westell Technologies technical
support line at 1.877.844.4274
CAUTION!
Power off before connecting/disconnecting cables.
Important Safety Information
Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. The outdoor antenna
used for the purpose of communicating to the wireless infrastructure is limited to 14 dBi gain, or any combination of gain
and loss that
equates to 14 dB at input. Each antenna must be positioned to observe minimum separation requirements
from all users and bystanders. The following guidelines should be used when considering separation distances.
