Record the serial number, model number, purchase date and point-of-sale company in the boxes in Figure P-1 below.  Retain this manual, along with proof of purchase, to serve as a permanent record of your purchase.   Figure P-1: Product Registration Information Safety Guidelines The general safety information in this section applies to both operating and service personnel.  Specific warnings and cautions are located in other parts of this manual to which 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 must 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 adjust this unit during an electrical storm.  We strongly recommend the use of a suitable lightning arrester. There are no user-serviceable parts inside the repeater.   DANGER! Hazardous  voltages  are  present  when  the  cover  is  removed.    Do  not  open  the repeater enclosure.  If you suspect a malfunction with this product, call your dealer or call Westell Technologies technical support line at 1.877.844.4274.  WARNING! Disconnect/remove power before connecting or disconnecting cables. Important Safety Information Antennas used  to radiate signals indoors are limited to a maximum gain of 3 dBi.  The outdoor antenna used  to communicate to the wireless infrastructure is limited to 14dBi gain, or any combination of gain and loss that equals 14 dB at input.  Position each antenna to observe minimum separation requirements from all users and bystanders.
Digital Repeater Line DSP85 Series                       WESTELL.COM © 2016 Westell Technologies                      14 June 2016 Doc. No. 960-1666-MNL rJ3 1.877.844.4274                            Page 12 of 77 Use the following guidelines when considering separation distances.  Place indoor antennas such that, under normal conditions, personnel cannot come within 20 cm (~8 in) from any inside antenna.  Adhering to this minimum separation ensures that bystanders cannot exceed RF exposures beyond the maximum permissible limit for uncontrolled exposure.  Position outdoor antennas such that, under normal conditions, personnel cannot approach closer than  183  cm  (~6  ft.).    If  a  directional  antenna  that  has  a  maximum  gain  of  14  dBi  is  used,  take precautions  to  prevent  personnel  from  routinely  passing  through  the  main  radiation  beam  at  a distance closer than specified. WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You must have an FCC LICENSE or express consent of an FCC Licensee to operate this device.

Adequate signal strength 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  is  typically  a  directional  type,  such  as  a  Yagi  antenna.  Internal  antennas  are  typically omnidirectional, though various other types may be used, depending on the coverage application.  The Westell DSP repeater  amplifies  both  the  uplink  (phone  to  tower)  and  downlink  (tower  to  phone)  signals,  facilitating communications to and from the intended wireless infrastructure. With a maximum total of 85 dB nominal gain on both the uplink and downlink, gain can be adjusted over a range from 53.5 dB to 85 dB in 0.5 dB steps.  The repeater is controlled with a computer connected to COM port 1 or 2 or via a crossover ethernet cable connected to the ethernet port. 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  DSP  configuration  parameters  must  change.    Configuration  parameters  are  created  at  the  factory  and supplied as files to be downloaded to the repeater.  The filter set configurations stored in memory determine the unit’s adaptability to various field applications.  Appendix B describes the band plans and the convention Westell uses to identify and store the files that make up the filter set.  All Westell repeaters are shipped with an active filter set that is programmed according to customer specifications. In most cases, the installer will not be required to program a filter. 1.2 Functional Overview Westell Technologies digital repeaters incorporate the following features for convenient operation, access, protection, and control:  Network configuration and control using either a web GUI accessed using a web browser or a menu driven user interface using the serial port.  The GUI does not require Internet access.

A blinking green LED (two seconds on/three seconds off) indicates a filter configuration file is loading.  IMPORTANT Do not unplug the repeater while it is in the boot-up process.  1.4 Local Communication Interface Ports To allow monitoring and control, Westell repeaters are equipped with four ports that provide external communication access: one ethernet, one DB-9 serial, and two USB ports.  The ethernet port is a primary communications port to the PC.  The serial interface provides communications to a local PC.  The USB interface provides a means to download files from a memory device.  The DB-9 pin assignments conform to the standard Electronic Industries Association (EIA232) specification.  A diagram of the pin descriptions is shown in Figure 1-1.   Figure 1-1: DB-9 Pin Descriptions  Connecting  a  serial  cable  to  the  COM  port  and  using  a  terminal  emulation  program  with  a  PC  will  allow communication to the control processor’s Text Menu Interface (TMI). 1.5 EIA232 Pin Specifications The connection diagram shown in Figure 1-1 is for reference only.  It is intended as a resource for pinout information if it is necessary to adapt your serial cable because of an unusual connector configuration.  In the majority of cases, this information is not needed. 1.6 USB Interface This port is used for software updates and filter file uploads.

Public safety DSP models have dry contacts for traditional alarm panel monitoring as well. 1.9 Circuit Operational Description The repeater uses a single down-conversion/up-conversion scheme.  There are multiple RF amplifier stages before each down-converting  mixer.   The down-converting  mixers are followed by  a single  IF amplifier.   A digital signal processor block processes the resultant digitized IF signal generated by an analog-to-digital converter.  The filtered digital  signal  is  fed  to  a  digital-to-analog  converter  and  then  up-converted  to  RF.  A  driver  amplifier  and  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. The net system gain value,  entered  manually, is  optimally  maintained  without  exceeding  FCC  parameters  or  overdriving  the A/D converters. The Status or Power/Fault LED provides immediate visual indication of the unit’s primary power alarm status.  The repeater features automatic shutdown protection as a safety measure if excessive drive is applied to the input or an oscillation condition occurs.  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 it is manually reset.  If recovery is established, the LED is illuminated green or available to be reset.  Events that trigger errors are saved in the event log.  1.10 Functional Block Diagrams

Verify that there are no cables with loose or poor connections.  RF leakage could cause oscillation to occur under some conditions. Check  the  rooftop  antenna  (donor  antenna),  if  directional,  for  proper  alignment  along  the  calculated  compass heading.  Typically, the directional antenna is aimed at the same site that your handset uses, but it may not always be.  It is critical that the installer contact the service provider for information about, and approval of, the selected cell site before the system is activated. IMPORTANT The installation height of the antenna for AWS band (1700/2100 MHz) operations is limited to 10 meters above ground for compliance with Section 27.50.  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 may be required to reject these unwanted signals.  In some instances, the donor antenna can be repositioned 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,  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. 2.2 Suggested Spectrum Analyzer Setting When  troubleshooting  RF  issues  and  surveying  challenging  RF  environments,  it  is  important  to  have  a  spectrum analyzer that is capable of measuring the frequency you are using.  Use an attenuator to protect the input when connected to a source of RF power, such as a repeater or a powered DAS. Measure both uplink and downlink.   Measure downlink on the donor cable and at the output (server) port of the powered repeater.  Measure uplink at the lead from the DAS (on fiber-powered DAS, where the lead would connect to the server port on the repeater) and at the donor port with the repeater power on.   Measurements may also be necessary at server antenna locations.  The spectrum analyzer must be equipped with a whip antenna. Set the resolution bandwidth (RBW) to 200 kHz for GSM and 1 MHz for CDMA.  If you cannot select these values, use the closest available values.  Set the video filter to about one-tenth of RBW.  Set other settings, such as span, to the appropriate values.  Ensure that there are no signals above the top of the screen. If you cannot see an adjacent out-of-band signal when using the 1 MHz RBW filter, decrease the RBW to see the close-in-frequency signals.  Set the RBW back when you want to measure the power level.

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.  It is important to consider the layout and placement of the system carefully. Refer  to  the  Preface  Safety  Guidelines  and  Important  Safety  Information  for  proper  antenna  selection  and installation.    DANGER! To avoid serious injury or death and repeater damage, do not install donor or server antennas  near  overhead  power  lines  or  high  power  components.    Allow  enough distance so that, if antennas fall, they will not contact those components. WARNING! 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. CAUTION Amplifier or handset damage may occur if a handset is connected directly to the repeater or to the coax that leads to the repeater.  2.4 Installation Guidelines 2.4.1 Donor Antenna  Accurately determine the azimuth to the donor cell site.   Obtain the donor site information and approval from the service provider/carrier.  Ensure that the radiation path to the donor cell site is as unobstructed as possible.  Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site.  Try to avoid having the RF signal from the donor pass above the location(s) of the service antennas.  Normally, service antennas are located behind and below the donor antenna (as viewed from above).  This approach will help avoid interference and feedback to and from the service antennas.  Normally, mounting the donor antenna higher will allow a less obstructed path to the donor site.  However, in high traffic metro areas avoid mounting the donor antenna any higher than necessary as the quality of the donor signal may start to become less stable and it is more likely to encounter adjacent channel interference.  When possible, shield the donor antenna’s rear by locating it so that HVAC units and/or penthouse structures are behind the antenna, relative to the donor cell site location.  Ground system components in accordance with NEC 810-15, 21 as required.

Use directional antennas indoors only in special cases when higher gain and directionality would be helpful and RF exposure limits will not be exceeded.  To avoid repeater uplink overload and gain limiting, mount the indoor antennas away from areas where mobile subscribers frequently use their phones such as desks or dispatch areas.  To determine the quantity and locations of indoor antennas, use an appropriate phone’s signal meter to determine areas of weak signals.  These are the approximate areas where indoor antennas may be needed.  Be aware the signal from an indoor antenna, in most cases, can be expected to penetrate about two standard office sheetrock-type walls to reach users.  After two walls, or if the walls are made of other materials, it may be necessary to split the available signal and add more antennas.  2.5 Optional Accessories A complete line of accessories is available from Westell.

If you do not,  the port may become disabled and the system will need to be rebooted.  4.2 Telnet Session (Remote Access) You may access the repeater using a LAN connection and a terminal emulation program for TCP/IP.  As with the serial connection, many terminal emulation programs will work, if properly configured.   In the following section, Tera Term is used to establish the Telnet session.  The network configuration of the computer and the repeater that is being controlled must be set up with the same subnet and subnet mask to establish a link.  In other words, the IP addresses of both the computer and the repeater  must use the same group of IP address number sets.   For example, the repeater ships with a default IP address of 192.168.1.100 and a subnet mask of 255.255.255.0, as shown in Figure 4-11.  To connect, the computer used for the link would normally need an IP address of, for example, 192.168.1.2 with a subnet mask of 255.255.255.0, the same subnet mask as the repeater.   In this example, the last digit of the IP address may be any number except 1,100 and 255.  Configuring your PC is straight forward, but it varies according  to  the operating  system  used.   If you  require assistance, contact  your  IT department or you may review the 4.4 Additional Tips section.

Avoid de-sensing of a nearby base station site. You can accomplish these goals by properly attenuating the antenna port(s) in the path of the donor antenna(s). 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 outcomes may 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 attenuation, 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. A.2 Server Port Server port attenuation may also be necessary, particularly where a powered DAS is present. The selection guidelines below apply to both server and donor ports. Use a signal generator to measure uplink signal strength properly.  If a signal generator is unavailable, place a test call while under the server antenna with the least path loss to the repeater. This method 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.  Choose accurate attenuator values 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 -25 dBm.

Input signals  exceeding  these  thresholds  will  result  in  composite  input  attenuation,  or  analog-to-digital  converter protection (ADC protect). Output power is reduced whenever the above thresholds are exceeded by reducing the gain by 1 dB for each 1 dB that the threshold is exceeded. Do not confuse ADC protect with AGC (automatic gain control), which reduces gain to prevent in-band (measured) output power from exceeding the specified maximum output level. Gain levels that would result in exceeding the rated output power of the repeater, e.g. 65dB of gain applied to an input signal  of  -30dBm, will  not  result  in  ADC protection, but  will  result  in  AGC.  Avoid continually operating  the repeater in AGC. To determine the total power applied to the donor and server ports, reference the composite input values as listed on the System Status page in the web GUI. A.4 Large Deltas between In-band and Composite Input Signals 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 3 dB Cellular, or more than 5 dB PCS, the maximum output power will be reduced.

Carefully consider the layout and placement of the system.  Set repeater gain well below line of sight donor path loss, as shown in C.1.1 Line of Sight  Propagation Path Loss  Table.  Higher gain settings may be possible if the internal building structure and system layout adds additional attenuation and the installer is confident about the values of that attenuation.

Brackets are provided for both options. Rack mounting a repeater requires two brackets mounted to the front corners of each module, Figure F-2.  Figure F-2: Rack Mounting Wall mounting uses four brackets, one at each corner.  Figure F-3: Wall Mounting NOTE  Westell 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.

The attachment system used to anchor the CBC to the wall must be able to support at least 8.4 lbs (3.8 kg). Use a wall anchoring system for the repeaters that can support at least 42.lbs (19.05 kg) for each dual band module and 23 lbs (10.43 kg) for each single band add on module. The power supplies are mounted approximately as shown.  Figure F-4: System Interconnect Interconnection of the repeaters in the rack or wall mount configuration requires the short RF jumpers supplied with the CBC Module. The actual interconnections will depend on the bands and cross band coupler module being used.
