Product Introduction
Cellular Specialties, Inc. (CSI) developed this digital repeater for use within enclosed structures where
sufficient signal from local cell sites to operate wireless phones is unavailable. Adequate signal must be
available outside the structure as a prerequisite to achieving in-building coverage. The Digital Repeater is
connected to an external antenna, usually on the roof, and to one or more internal antennas placed
strategically throughout the area where wireless service is desired.
The external antenna typically is directional, such as a “yagi”. Internal antennas are typically omnidirec-
tional, although various other types may be used depending on the coverage application. The repeater
amplifies both the “uplink”(phone to tower) & “downlink”(tower to phone) signals thus facilitating
communications to and from the intended wireless infrastructure.
With a maximum total of +85dB nominal gain on both the up and down links, gain can be adjusted over a
range from +53.5dB to +85dB in 0.5dB steps. Control of the repeater is achieved utilizing a computer
connected to comm. port 1 or 2 or via a Crossover Ethernet cable connected to the Ethernet port. There
are also an LED indicator indicate ALARM status.
A specific filtering process modifies each amplification chain. This process digitally converts the assigned
spectrum and then applies digital signal processing (DSP) techniques. DSP is used to create passbands
that selects the RF energy passing through either the uplink or downlink paths.After the digital processing
is complete, the information is converted back to an analog signal that is applied to the remaining stages
of amplification. The resulting signals emitted by the repeater are specific to the network service providers’
requirements. If these requirements change, only the DSPconfiguration parameters need change in order
to adapt. Configuration parameters are created at the factory and supplied as files that may be down-
loaded to the repeater. The filter set configurations stored in memory determine the unit’s adaptability to
various field applications. The following pages describe the PCS band plan as well as the convention CSI
uses to identify and store the files that make up the filter set. All units are shipped with an active filter set
that is programmed according to the ordering parties’ specifications. In most cases, the installer will not
have to program a filter.
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 14dBi gain, or any combination of gain and loss that equates to
14dB 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.
INDOOR antennas must be placed such that, under normal conditions, personnel cannot come within 20 cm (~8.0 in.) from any inside
antenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF exposures beyond the
maximum permissible limit as defined by section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.
OUTDOOR antenna must be positioned such that, under normal conditions, personnel cannot approach closer than 183 cm. (~6 ft.). A
directional antenna having a maximum gain of 14 dBi is used, precautions should be taken to prevent personnel from routinely passing
through the main radiation beam at a distance closer than specified.

LED Indicator
Automatic safety precautions are built into the amplifier system. In the case of a catastrophic system
event, a shutdown circuit is incorporated that will disable all emissions should the uplink input or downlink
input be over driven or should an oscillation or output overpower event occur. The amplifier will periodi-
cally attempt to recover from the detected condition automatically.
*Note: During Power up, the repeater will require a approximately three minutes for
the internal computer to boot up. During this time the LED on the front panel may light
and go out several times.
Do not unplug the unit while it is in the boot up process!
When a boot up is complete and no alarm conditions exist, the LED indicator will be illuminated green.
Should a fault condition develop the LED will illuminate red and the user may check the status page
of the GUI for the nature of the fault.*

EIA232 Pin Specifications
The diagram above is for reference only, it’s intended to provide a quick source for pinout
information in the event it should be necessary to adapt your serial cable because of an
unusual connector configuration. In the vast majority of cases this information will not be
needed.
Local Communication Interface Ports
To allow monitoring and control, the repeater is equipped with four ports that provide external
communication access (1 Ethernet CAT-5, 2 DB-9 serial, and 1 USB). The Ethernet, CAT-5 port
is provided as a primary communications port to the PC. One serial interface provides commu-
nications to local PC and the second to an external modem when provided. The USB interface
provides a means to download files from a memory device and may also be used by an
external modem. The DB-9 pin assignments conform to the standard Electronic Industries
Association (EIA232) specification. A diagram of the pin descriptions is provided on this page
for reference.
Connecting a null modem cable to one of the COM ports and using a terminal emulation
program with a PC will allow communication to the control processor’s Text Menu Interface
(TMI). See command line interface section for further detail.
Monitoring & Alarms
There are no physical connections provided to specifically communicate system or alarm
status. This information is embedded in the information accessible via the communication
ports described earlier.
USB Interface
The Universal Serial Bus (USB) interface conforms to Intel’s Universal Host Controller
Interface (UHCI) version 1.1 dated March 21, 1996. This interface will support data
transfer rates up to 12 Mbps and can be used for software updates and filter file
uploads.
Ethernet
The Ethernet AUI conforms to IEEE 802.3 and is capable of supporting 10/100 Mbps
communications speeds. This port is used to provide access to the GUI.

System Set-Up Considerations
All cables should be checked for shorts and opens. Also verify that there are no cables with loose or poor
connections. RF leakage could cause oscillation to occur under some conditions.
The rooftop antenna (Donor Antenna), if directional, should be checked for proper alignment along the calculated
compass heading. Typically, the directional antenna would be aimed at the same site that your handset uses, but it
may not always be so. It is critical the installer contact the service provider for information on, and
approval of, the cell site he or she has selected before the system is turned on.
If cables and alignment are acceptable and a problem persists, it may be necessary to use a spectrum analyzer to
examine the signal environment in which the repeater is operating. The existence of strong adjacent channel
signals within the frequency band(s) can cause the AGC to reduce the amplifier’s gain or cause alarms. In some
cases additional filtering or attenuation might be required to reject these unwanted signals. In some instances, the
donor antenna can be reoriented horizontally, to place the interference source in an antenna pattern “null”. There
also may be some cases where the interference from outside signals is so great that they cannot be filtered or
otherwise reduced or eliminated without expensive and possibly prohibitive measures. In these cases it may not
be practical to use the repeater for providing coverage to these sites.
Selection of external attenuators to be used in line with the Antenna Port(s):
1:1 PORT CONFIGURATION
Input: One single band duplex port, from the dual band donor.
Output: One single band duplex port to the DAS.
DONORPORT
If a unit is installed in an area with very strong desired and/or undesired signals, it is important to ensure that the
overall signal levels are optimized to be within the best operating range of the repeater. Additionally, de-sensing of a
nearby base station site must be avoided. These goals can be accomplished by properly attenuating the antenna
port(s) in the path of the donor antenna(s). In effect, one can imagine that the particular repeater deployment is
electrically moved farther from the base station using attenuators that are equivalent to increasing the path loss from
the donor antenna to the base station. The following potential outcomes result from the use of attenuators on the
donor port(s) of the repeater: Uplink output power, as reported by the unit, is reduced by the value of the attenua-
tion, protecting nearby base stations. Downlink signal to noise ratio is high at the point of the attenuator, resulting in
slight but negligible reduction in downlink performance. Other performance is essentially unchanged.
SERVERPORT
Server port attenuation may also be necessary, particularly where a powered DAS is present. The selection guide-
lines below apply to both server and donor ports. In order to properly measure uplink signal strength, a signal
generator should be used. If a signal generator is not available, placing a test call while under the server antenna
with the least path loss to the repeater should provide reasonable data.
The following potential outcomes result from the use of attenuators on the server port(s) of the repeater: Downlink
output power, as reported by the unit, is reduced by the value of the attenuation. Uplink incoming power from the
DAS is reduced, along with potentially strong and/or harmful out-of-band signals (including noise) that are generated
by the DAS.

-11 -
Attenuator Selection Guidelines:
Accurate attenuator values need to be chosen to ensure that the maximum total power (higher of Composite or In-
Band Input) applied to the donor and server port(s) does not exceed the following thresholds:
Input Signal Max Gain Input Signal Max Gain
<-45 dBm 85 dB -32.2 dBm 69 dB
-44.3 dBm 84 dB -31.4 dBm 68 dB
-43.6 dBm 83 dB -30.6 dBm 67 dB
-42.9 dBm 82 dB -29.8 dBm 66 dB
-42.2 dBm 81 dB -29 dBm 65 dB
-41.5 dBm 80 dB -28.2 dBm 64 dB
-40.6 dBm 79 dB -27.4 dBm 63 dB
-39.7 dBm 78 dB -26.6 dBm 62 dB
-38.8 dBm 77 dB -25.8 dBm 61 dB
-37.9 dBm 76 dB -25 dBm 60 dB
-37 dBm 75 dB -24.4 dBm 59 dB*
-36.2 dBm 74 dB -23.8 dBm 58 dB*
-35.4 dBm 73 dB -23.2 dBm 57 dB*
-34.6 dBm 72 dB -22.6 dBm 56 dB*
-33.8 dBm 71 dB -22 dBm < 55 dB*
-33 dBm 70 dB
*We recommend padding this level due to potential for fluctuating signal.
-25 dBm is the maximum input signal level that should be applied to the repeater, even if the gain is lower than 55 dB.
Input signals exceeding these thresholds will result in composite input attenuation, called “ADC Protect” (Analog to Digital
Converter Protection). Output power is reduced whenever the above thresholds are exceeded by reducing the gain by 1dB for
each 1 dB that the threshold is exceeded. ADC Protect should not be confused with AGC (Automatic Gain Control), which
reduces gain to prevent In-Band (measured) output power from exceeding the specified maximum output level.
To determine the total power applied to the donor and server ports, please reference the “Composite Input” values as reported in
the Web (“System Status”) or Menu (“Link Status”) interfaces (depicted and explained later in this manual).
Large delta’s between in-band and composite input signals:
Care should be taken to isolate the best donor site to ensure the least possible delta between in-band and composite downlink
signals.
If the (downlink) composite input exceeds the in-band input by more than 5 dB, the maximum output power will be reduced.
Example:
AWS Band
In-Band Input -45 dBm
Composite Input -38 dBm
Max Gain = 68 dB
Max Output = 23 dBm

Mounting the Digital Repeater
The following diagrams illustrates the methods for mounting the repeater(s) in a typical wall or rack installation.
Brackets are provided for both options. Note: Dual and single band modules are shown for illustration purposes.
Rack mount of the repeaters requires just two brackets mounted to the front corners of each module. Note: the CSI digital repeaters
must be supported in the rack system with a shelf or slide rail. Do not rely on the brackets exclusively to support all the
weight of the modules.
Mount the Cross Band Coupler on the wall close enough
to the repeater modules to allow the RF jumpers to reach
from the CBC to the repeaters. The attachment system
used to anchor the CBC to the wall must be able to
support at lease 8.4 lbs / 3.8 kg.
The wall anchoring system you use for the repeaters
will need to be able to support at lease 39.2 lbs/ 17.8
kg for each dual band module and 23.2 lbs/ 10.5 kg for
each single band add on module. The power supplies
are mounted approxamately as shown.

Circuit Operational Description
The repeater uses a single down-conversion/up-conversion scheme. There are multiple RF amplifier stages
prior to each down-converting mixer. The down-converting mixers are followed by a single IF amplifier. A Digital
Signal Processor block then processes the resultant digitized IF signal that was previously generated by an
Analog-to-Digital Converter. The processed (filtered) digital signal is fed to a Digital-to-Analog converter and then
up-converted to RF. A driver amplifier and a final power amplifier make up the final gain stages before application
to the diplexer. The maximum total system gain (diplexer input to diplexer output) is nominally 85 dB for either the
downlink or the uplink paths with both links having independent manual and automatic gain controls (AGC).
AGC reacts to analog power detection on both the input and output of the uplink and downlink RF chains.
A control algorithm continuously monitors these detected values and dynamically adjusts various gain
stages such that the net system gain value, entered manually, is optimally maintained without either
exceeding FCC parameters or overdriving the A/D converters.
An LED on the front panel provides immediate visual indications of the unit’s primary power and major or
minor alarm status. The repeater features automatic shutdown protection, as a safety measure, should
excessive drive be applied to the input or an oscillation condition occur. When in a protected mode, a
control algorithm determines the appropriate method of recovery to a normal, previously defined state, or
maintains the protection until manually reset. If recovery has been established, the LED will either be
extinguished or available to be reset. The events that trigger the error will be saved in the event log.
Important Installation Notes
•Inadequate isolation between the outside and inside antennas may cause regenerative
feedback in the system. This feedback can cause the amplifier to emit a continuous signal at
maximum amplitude and, in some cases, interfere with normal operation of the cell site. Careful
consideration of the layout and placement of the system is imperative.
•The installer should refer to the Safety Guidelines section on page 4 and the Important Safety
Information section on page 5 for proper antenna selection and installation. To avoid serious injury or
death and damage to the repeater, do not install donor or server antennas near overhead power lines
or high power components. Allow enough distance so that if antennas should fall they will not come
in contact with those components.
••
••
•Close proximity to the donor or server antennas with the repeater in operation may expose
the user or installer to RF fields that exceed FCC limits for human exposure.

referred to the user’s IT department or you may refer to the Additional Tips section at the end
of this manual.) When connection is made the user will be prompted for a user name and
password. For the purpose of the GUI session, the default user name is webuser and the
password is csi1234. This can also be changed as required. Internet access is not required
to use the GUI. (Note: If you are connecting using a laptop, verify that your Ethernet port is
powered. Some laptops will not allow Ethernet connection when on battery power. If this is
the case with the laptop you are using you will need to plug it in or update the power settings.)

If the user would like to modify RF configuration click on the words RF Configuration in the
navigation box and the screen below is displayed.
The user may select the desired filter by pressing the band/sub-band and modulation selection
buttons. Undesired bands/sub-bands if lit will require the user to manually “deselect” them before
programming. Pressing the Program button will complete the selection and load the desired filter.
The time required to complete this process will take just a few moments. Note: If the filter desired
is not currently in the unit, additional filters along with instructions on how to load them are
available by contacting CSI.
To change gain settings the user will select the Uplink only or Uplink and Downlink radio buttons.
The user then inputs the gain value desired. Gain values from 53.5 dB to 85.0 dB may be selected.
The repeater will not allow the user to set values outside this range. By pressing the Change
Settings button the gain change is implemented. When a new filter set is required, it may be
selected by clicking Program a Filter in the navigation box.
