Digital Repeater Line DSP85 Series WESTELL.COM © 2016 Westell Technologies 4 May 2016 Doc. No. 960-1666-MNL rJ 1.877.844.4274 Page 12 of 74 1 Product Overview 1.1 Product Information Westell Technologies digital repeaters were developed for use within enclosed structures where sufficient signal strength from local cell sites to operate cell phones is unavailable. 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 typically is 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 digital repeaters incorporate the following features for convenient operation, access, protection, and control:  Network configuration and control using either a Web page style GUI accessed using a web browser or a menu driven user interface using the serial port. The GUI does not require Internet access.  User gain control (affects all passbands)  Automatic gain control  Automatic power control  Overdrive protection (PA limiting)  Under/Over voltage protection  Fault protection  Alarm notification - local/remote
Digital Repeater Line DSP85 Series WESTELL.COM © 2016 Westell Technologies 4 May 2016 Doc. No. 960-1666-MNL rJ 1.877.844.4274 Page 13 of 74  Upgrade support - local/remote  External interfaces - USB/ethernet/Serial  Re-loadable filters - local/remote  Web-based monitoring and control - local/remote  Persistent status and error information 1.3 LED Indicator Westell automatic safety precautions are built into the amplifier system. In the case of a catastrophic system event, a shutdown circuit will disable all emissions if the uplink input or downlink input is overdriven or if an oscillation or output overpower event occurs. The amplifier will periodically attempt to recover from the detected condition. Warning light indicators are: Status LED:  Blinking yellow: Unit is migrating the database after an upgrade  Blinking red: Unit is programming the filter(s) and there is an error condition  Blinking green: Boot up or unit is programming the filter(s) and no error condition exists  Solid green: Unit is operational, PA is on  Solid yellow: Unit is operational, but AGC is on  Solid red: Unit has an error condition or PA is off  Dark: Unit is not powered Check the status page of the GUI for the nature of the fault. NOTE On power up, the repeater requires approximately three minutes for the internal computer to boot. During this time, the LED labeled Power/Fault or Status will slowly blink green on and off at a rate of approximately 1 Hz. This will indicate that the unit is in the boot up process. 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.

No. 960-1666-MNL rJ 1.877.844.4274 Page 14 of 74 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. One 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. 1.7 Ethernet This port is used to provide local or remote access to the GUI. 1.8 Monitoring and Alarms The DSP85 Series can be monitored via an ethernet connection using SNMP, SSH and/or HTTP protocols. Public safety DSP models have dry contacts for traditional alarm panel monitoring as well.
Digital Repeater Line DSP85 Series WESTELL.COM © 2016 Westell Technologies 4 May 2016 Doc. No. 960-1666-MNL rJ 1.877.844.4274 Page 15 of 74 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.

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.
Digital Repeater Line DSP85 Series WESTELL.COM © 2016 Westell Technologies 4 May 2016 Doc. No. 960-1666-MNL rJ 1.877.844.4274 Page 18 of 74 2.3 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. It is important to carefully consider the layout and placement of the system. 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 backside by locating it so that any 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.
Digital Repeater Line DSP85 Series WESTELL.COM © 2016 Westell Technologies 4 May 2016 Doc. No. 960-1666-MNL rJ 1.877.844.4274 Page 19 of 74 2.4.2 Antennas  Use omnidirectional antennas indoors, and locate them centrally with respect to the intended coverage area to minimize signal leakage to the outside. 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.

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.

No. 960-1666-MNL rJ 1.877.844.4274 Page 47 of 74 Appendix A Attenuation and Dynamic Range Guidelines A.1 Donor Port If a repeater is installed in an area with very strong wanted and/or unwanted 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 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 running the repeater in constant 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.

Brackets are provided for both options. Rack mount of the repeaters requires two brackets mounted to the front corners of each module, Figure F-1. Figure F-1: Rack Mounting Wall mounting uses four brackets, one at each corner. Figure F-2: Wall Mounting
Digital Repeater Line DSP85 Series WESTELL.COM © 2016 Westell Technologies 4 May 2016 Doc. No. 960-1666-MNL rJ 1.877.844.4274 Page 72 of 74 NOTE The 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. 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 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-3: 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. Contact Westell’s technical support line at 1.877.844.4274 should you have questions about your specific application.
