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 120 cm.

(~4 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.

only Memory Product Introduction Cellular Specialties, Inc. (CSI) developed the DSP85 digital repeater for use within enclosed structures where signal from local dispatch sites is insufficient to operate on scene communication equipment. Adequate signal must be available outside the structure as a prerequi-

site 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 omnidirectional, although various other types may be used depending on the coverage application. The CSI DSP Repeater amplifies both the uplink (Transceiver to tower) &

downlink(tower to Transceiver) 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 LED indicators near the display to indicate ALARM status, AGC status, UL PWR, DL PWR, OSC, SHUT DWN and a D/L SIGNAL STRENGTH bargraph. 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 require-

ments. If these requirements change, only the DSP configuration parameters need change in order to adapt. Configuration parameters are created at the factory and supplied as files that may be downloaded to the repeater. The filter set configurations stored in memory determine the units adaptability to various field applications. The following pages describe the public safety band plan as well as the convention CSI uses to identify and store the files that make up the filter set. All DSP85-PSS8 repeaters 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.

Functional Overview The CSI-DSP85-PSS8 repeater incorporates the following features for convenient operation, access, protection, and control. Network Configuration and Control using either a webpage style GUI through any standard browser or a menu driven user interface using the serial port.

(Note: GUI does not require Internet access.) User Gain Control (affects all passbands) Automatic Gain Control Automatic Power Control Oscillation Protection Over Drive Protection (P.A. limiting) Under/Over Voltage Protection Fault Protection Alarm Notification - Local/Remote 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 LED Indicators 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 overdriven or should an oscillation or output overpower event occur. The amplifier will periodically attempt to recover from the detected condition automatically. Warning light indicators are as follows:

Alarm:

AGC:

UL PWR:

DL PWR:

OSC:

SHUT DWN:

Indicated by a red LED. The unit has sensed an alarm condition. This LED may light alone or in conjunction with one of the other indicator LEDs. In both cases the cause(s) can be reviewed by going to the System Health menu. When Illuminated, this yellow LED indicates that automatic gain control is active and has reduced the gain of the unit in order to prevent very strong input signals from overloading the amplifier. The amplifier will periodically evaluate input signal and attempt to recover from this condition. Indicated by a red LED. Uplink power has been affected by a system event and will need to be addressed by either the system software or a technician to be reset to original system settings, using the GUI or text menu interface. See the event log to determine the nature of the fault. Indicated by a red LED. Downlink power has been affected by a system event or condition, such as insufficient antenna isolation, and will need to be addressed by either the system software or a technician to be reset to original system settings, using the GUI or menu driven user interface. See the event log to determine the nature of the fault. Indicated by a red LED. An oscillation event has occurred or is occurring. The system has been affected by the event and the problem will need to be addressed by the system software or a technician to be reset to original ystem settings. This is an indication of a major fault. Indicated by a red LED. The RF stages of the unit are disabled due to an unresolved system event such as oscillation, effectively taking the unit off the air. The problem will need to be addressed by a technician before the on air operation can be restarted. The repeater is not equipped with an ON/OFF power switch. Hard power down will require that the unit be unplugged. D/L SIGNAL STRENGTH:

Indicated by a green LED bargraph. This indicates the relative signal strength being received from the cell site. Note: the last bar of the bargraph will turn red in the event of very strong adjacent channel interference.

*Note: During Power up, the CSI-DSP85-PSS8 will require a approximately three minutes for the internal computer to boot up. During this time the LEDs on the front panel will light and go out several times. When boot is complete and no alarm conditions exist, none of the LED indicators will be illuminated. The CSI logo is illuminated when ever the repeater is powered. One or more bars on the LED bargraph may also be lit, depending on the strength of the signal being received from the donor site. Signals weaker than -81dBM will not illuminate any bars. Do not unplug the unit while it is in the boot up process!

Local Communication Interface Ports To allow monitoring and control, the CSI-DSP85-PSS8 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 communications 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 assign-

ments 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 processors Text Menu Interface (TMI). See command line interface section for further detail. EIA232 Pin Specifications The diagram to the left is for reference only, its 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. USB Interface The Universal Serial Bus (USB) interface conforms to Intels 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 soft-

ware 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.

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. 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 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 CSI-DSP85-PSS8 is operating. The existence of strong adjacent channel signals within the frequency band(s) can cause the AGC to reduce the amplifiers 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 CSI-DSP85-PSS8 for providing coverage to these sites. Selection of external attenuators to be used in line with the CSI-DSP85 Antenna Port(s):

DONOR PORT (To Outside Antenna, see port configuration diagram next page.) If a CSI-DSP85 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 CSI-DSP85: Uplink output power, as reported by the CSI-

DSP85, 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. SERVER PORT (To Inside Antenna(s), see port configuration diagram next page.) 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. 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 CSI-DSP85:

Downlink output power, as reported by the CSI-DSP85, 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.

TO INSIDE ANTENNA TO OUTSIDE ANTENNA 1:1 PORT CONFIGURATION STANDARD MODEL Input: One single band port, from the single band donor. Output: One single band port to the DAS. 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:

*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 deltas 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 3 dB for the SMR band the maximum output power will be reduced. Example:

Band (SMR) In-Band Input -45 dBm Composite Input -38 dBm Max Gain = 68 dB Max Output = 23 dBm

model number: CSI-RWM-DSP85 Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. This Important Installation Notes feedback can cause the amplifier to emit a continuous signal at maximum amplitude and, in some cases, interfere with normal operation of the dispatch 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. WARNING! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE REPEATER OR THE COAX THAT LEADS TO THE REPEATER. 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 maintained without either exceeding FCC parameters or overdriving the A/D converters. LEDs on the front panel display provide immediate visual indications of the units 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 estab-

lished, the associated LED(s) will either be extinguished or available to be reset. The events that trigger the error will be saved in the event log.

Web based GUI Session Primary access to the repeater is gained using a LAN connection and a web browser program such as Firefox by Mozilla, or Internet Explorer from Microsoft. The repeater ships with the default IP address of 192.168.1.100, but it can be changed later if required. If connecting directly to the repeater from a laptop or PC with a crossover CAT-5E cable or over a LAN the user types the IP address of the repeater into the browser address line to connect. (Note: Most users will need to update the TCP/IP settings on their computer to enable connection to a host that has a static IP. Select Use the following IP Address and enter the IP Address as follows: 192.168.1.x, where x = any number from 2 to 254 inclusive other than 100. The subnet mask is 255.255.255.0. Questions pertaining to these settings should be referred to the users 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.) System Status:

When login is complete the user is brought to the system status page. The links shown in the navagation box on the left are activated by clicking on them.

Log Configuration:

The Log Configuration page provides the user with the means to modify three aspects of how log files are created and stored as shown below. To end the session exit the browser, the user will be automatically logged out. Text Menu Interface (Local Access) Local access to the repeater TMI, also known as the console interface, is made by connecting a serial cable (optional), as shown in figure 1, from the serial connector of the laptop to either of the serial ports on the bottom end panel of the repeater. These connectors are labeled COM 1 and COM 2. In some cases, if the gender of the connector is not the same as shown in figure 1, a null modem adapter (optional) as shown in figure 2 may also be required. Figure 1 Figure 2

Terminal Emulation Program Many terminal emulation programs will work if properly configured. In the following description, TeraTerm is used to establish the TMI session. This program is readily available via the Internet and is free from Ayera Technologies at:

http://www.ayera.com/teraterm/

TeraTerm Pro Web works on Windows 95/98, 2000, XP. Here is the latest TeraTerm Pro Web release:

Version 3.1.3, October 8, 2002. ttpro313.zip When the program is started, the following screen is displayed. Select the Serial radio button and press OK as shown below. Note: It may be necessary, in the System Properties section of the control panel; using Device Manager to determine what COM port your computer uses for the communications port. In this case it is COM 1. This is not to be confused with the serial port on the bottom panel of the repeater labeled COM 1.

-24-

Terminal Program Set-Up Pressing OK will open up a blank dialog screen. Go to the setup dropdown menu and select Serial port to make changes to the serial port setup. Configure the terminal program for the correct COM port, in this case COM 1 and 115200 baud rate as shown below.

-25-

TMI Login After completing the serial port changes (pressing the enter key will be required to complete the action) the user will be prompted for a user name and password. The default user name is user. The password is csi1234. After entering the password and pressing return the TMI main menu will appear. Note: by default the Set Parameters option is disabled. To re-enable the user will press 1 and will be prompted for a username and password. The default user name is csi and the password is csi1234. The actions displayed are self-explanatory. Pressing 1 will continue to expand this session screen and allow the following parameters to be set.

-26-

Each Set Parameter selection, when chosen will be expanded to allow changing or setting of that parameter. For example from the Link Configuration menu on the previous page, selecting 1 - Adjust Gain will display the menu shown below. After selecting option 1, downlink, the current user gain is displayed and the option to change it is accomplished by typing the desired gain at the prompt. The user is then returned to the previous menu.

-27-

All the other options operate in much the same way. Some of the options will offer the user additional selections and will be self-explanatory. Below is one example of these additional options, the one shown below is the result of selecting (3) Filter Programming. Note: Graceful session termination is important. Use Disconnect under the file dropdown menu to terminate a session, otherwise the port may become disabled and force the system to be rebooted. Telnet Session (Remote Access) Remote access to the repeater may be gained through 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 description, TeraTerm is used to establish the Telnet session. Also, it will be required that the network configuration of the computer and the repeater being controlled be set up with the same Sub Net and Sub Net Mask in order to establish a link. In other words, the IP addresses of both the computer used and the repeater must use the same group of IP address number sets. For example, the repeater ships with the default IP address of 192.168.1.100 and a Sub Net Mask of 255.255.255.0. In order to connect, the computer to be used for the link would normally need an IP address of something like 192.168.1.12 with a Sub Net Mask of 255.255.255.0, the same Sub Net Mask as the repeater. In this example note: the last digit of the IP address may be any number except 1,100 and 255. Configuring your PC is normally fairly straight forward but it does vary somewhat with the operating system involved. If you require assistance, contact your IT department and they will be able to set up your PC for you or you may review the Additional Tips Section at the end of the manual. When the TeraTerm program is started, the following screen is displayed. Change the default host IP address to the IP address of the repeater to be controlled. In the case of a new install, the default address is 192.168.1.100 and has been assigned at the factory. Select the service Telnet. The TCP Port must be 23.

-28-

Pressing the OK button will bring the user to the following screen, which will require the user to log in. The default user name is user. The default password is csi1234. In the field after the prompt DSP85-cell-X login; type the user name and password. After typing the password press the enter key and the main menu will be displayed as shown next.

-29-

Telnet and serial sessions both provide access to the same Text Menu Interface. We have already shown many of the options available and all are self explanatory, so they will not be repeated. Modem Interface (Remote Access with login) A modem can also be used to gain remote access to the unit provided the repeater has been properly equipped. A selection of modems is available as an option. If the modem requires a SIM card for activation, special requirements must be met for the SIM card to become fully functional, contact the service provider. In addition, an IP address must be obtained and entered into the CSI-

DSP85-PSS8. Once the modem has been installed and activated, it can be accessed from any terminal emulation program just as in the serial and Telnet examples provided earlier. Access response time will depend on many factors, some of which are:

Quality of the connection (RF signal in the case of wireless modems) Technology (CDMA, EDGE, GPRS, etc.) Network congestion (Throughput) When a connection has been established, the same login screen shown in both the serial and Telnet examples is presented.

Additional Tips Instructions to change TCP/IP settings on your Windows computer. Click in the Network Connections Icon in the Control Panel. See below. Right click on Local Area Connection - and select Properties. Scroll down to Internet Protocol (TCP/IP) and click on the Properties button.

-31-

If you are set up to use DHCP, the window shown below will be displayed. Select Use the following IP address: and enter 192.168.1.2. The subnet mask should automatically populate to 255.255.255.0. Nothing else will need to be chosen or entered. Click OK, then OK again and retry connection. A crossover Ethernet cable (supplied) must be used for Web Interface access. As a reminder, you must verify the Ethernet port on your laptop is powered. If your laptop is on battery power, the Ethernet port may be inactive by default. If this is the case simply plug in the laptop to a 110vac source or change the power settings to enable the Ethernet port when the laptop is using battery power.

Suggested spectrum analyzer setting:

When troubleshooting RF issues, and when surveying challenging RF environ-

ments, its important to have a spectrum analyzer capable of measuring the frequency that you are working with. An attenuator should be used to protect the input, when connected to a source of RF power such as the repeater or a powered DAS. Both Uplink and Downlink should be measured. Downlink should be measured on the donor cable and at the output (server) port of the powered up repeater, and Uplink at the lead from the DAS (on fiber/powered DASs, where the lead would connect to the server port on the repeater) and at the donor port with the repeater powered up. Measurements may also be necessary at server antenna locations. Your spectrum analyzer will need to be equipped with a whip antenna for this. Resolution Bandwidth (RBW) should be set at 200 kHz for GSM and 1 MHz for CDMA. If you cannot select these values, the closest available values should be used. Video filter should be about one tenth of RBW. Other settings like span are whatever is appropriate. One should also make sure 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, you can decrease the RBW, to see the close-in-frequency signals. Be sure to set the RBW back when you want to measure the power level. RF Notes:

To prevent overload of the DSP input stages, the maximum measured level of in-

band or out of band signals should be less than -50 dBm when the DSP gain is set to 85 dB, -40 dBm when set to 75 dB, etc. This applies when there is one dominant signal and applies TO BOTH THE DOWNLINK AND UPLINK. If there are two dominant signals, and the gain is set to 85 dB, then the level of each signal should be kept to less than -53 dBm. With three signals, each should be less than -55 dBm. With ten signals each should be less than -60 dBm. This latter reduction prevents the composite power of the multiple signals from exceeding an acceptable level. Add fixed attenuators in line with the donor antenna line/

DAS feed to keep signals below the levels indicated above.
