(CSI) developed the Wireless Engine digital repeater for use within enclosed structures where sufficient signal from local cell sites to operate cell 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 CSIs DSP 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 +55dB to +85dB in 0.5dB steps. Control of the repeater is achieved utilizing a computer connected to comm. port 1 or 2 or via 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 requirements. 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 down-

loaded to the repeater. The filter set configurations stored in memory determine the units adaptability to various field applications. The following pages describe the Cellular and PCS band plans as well as the convention CSI uses to identify and store the files that make up the filter set.

In both cases the cause(s) can be review by going to the System Health menu. Indicated by a yellow LED. The gain of the unit has been reduced in order to prevent very strong input signals from overloading the amplifier. The amplifier will attempt to recover from this condition at periodic intervals. Indicated by a red LED. Uplink power has been affected by a system event and will need to been 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. Downlink 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 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 system 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, for a hard power down the unit is unplugged. 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.

Local Communication Interface Ports To allow monitoring and control, the CSI-DSP85-CP 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 internal or external modem. The DB-9 pin assignments conform to the standard Elec-

tronic 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 Command Line Interface

(CLI). See command line interface section for further detail. EIA232 Pin Specifications The diagram above 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.

- 7 -

USB Interface The Universal Serial Port (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. Ethernet The Ethernet AUI conforms to IEEE 802.3 and is capable of supporting 10/100 Mbps communications speeds. Monitoring & Alarms There are no physical connections provided to specifically communicate system status or alarm status. This information is embedded in data accessible via the communication ports described earlier. Troubleshooting All cables should be checked for shorts and opens. 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 the problem persists, it may be necessary to use a spectrum analyzer to examine the signal environment in which the CSI-DSP85-CP is operating. The existence of strong signals within the frequency bands can cause the AGC to reduce the amplifiers gain. In some cases additional filtering might be required to reject these unwanted signals. In some instances, the directional outside 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-CP for providing coverage to these sites.

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 precautions, in the following section, 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.

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. 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 established, the associated LED(s) will either be extinguished or available to be reset. The events that trigger the error will be save in the event log. Digital signal processing is performed concurrently on the complete spectral band allocation. Therefore, in the case of the US PCS band, digitization of 60 MHz (up or down links) is first accomplished. Next, Filter Files are applied to a mathematical algorithm that has been established in a specialized Field Programmable Gate Array (FPGA) processor. The filter file used in the DSP process is stored in nonvolatile memory and recalled when a filter set is required. Remaining sets are stored in flash memory. Because of the size of the filter files, replacing the EEPROM file with one stored in flash memory takes just a few moments.

Web based GUI Session Primary access to the repeater can is gained thru 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 as required and in the following examples we will be using an address of 192.168.1.41. If connecting directly to the CSI-DSP85-CP from a laptop or PC with a crossover CAT-5E cable or over a LAN the user only needs to type the IP address of the repeater into the browser address line to connect. At this point the user will be prompted for a user name and password. For the purpose of the GUI session, the default user name is dualband and the password is csi1234. Please note this can be changed as required. Note: internet accsess is not required to use the GUI. When login is complete the user is brought to the system status page. The links on the page are activated by clicking on them. Note: some of the settings available in the CLI are not available in the GUI session.

-16 -

If the user selects Local Network from the System Status page, the following screen is displayed and from here network configuration can be modified as required. The default is set to Static, check with your IT department for explanation and approval of the DHCP and DHCP Server options before you seletct them. After any changes are made press the refresh button to review the fields and assure the change made is correct. Note: changing network settings may cause the current TCP/IP connec-

tion to fail because change will take effect immediately.

- 17 -

From here the user may return to the System Status screen or click on the other options. If the user would like to modify RF configuration click on the words RF Configuration in the brown navigation box and the screen below is displayed. The user 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. If a new filter set is required, the new filter may be selected from the Program a Filter page below.

- 18 -

The user may select the desired filter from the dropdown menu. Pressing the Program button will complete the selection and load the desired filter. Note: the time required to complete this process will take just a few moments. Note: If the filter desired is not currently in the list, additional filters along with instructions on how to load them are available by contacting CSI. When the CSI-DSP85-CP includes an internal modem requiring provisioning for the service providers network click on Remote Network in the brown navigation box and the screen below is displayed.

- 19 -

Highlight the carrier for whom you want to configure the modem for and click the Change Settings button. Note: the system will require restart for the change to take effect. By clicking System Health the current state of the CSI-DSP85-CP can be reviewed.

- 20 -

Clicking Diagnostics will bring up the page shown below. The Diagnostics page will show addi-

tional data not found on the System Status page. If a reboot of the repeater becomes necessary click on the Reboot option in the brown navigation box and the Reboot page is displayed. To end the session exit the browser, the user will be automatically logged out.

- 21 -

Command Line Interface (Local Access) Local access to the CSI-DSP85-CP CLI, also known as the console interface, is made by connecting a serial cable, as shown in figure 1, from the serial connector of the laptop to ether of the serial ports on the bottom end panel of the FAR. These connectors are labled COM 1 and COM 2. In some cases, if the gender of the connector is not the same as shown, a null modem adapter as shown in figure 2 may also be required. Figure 1 Figure 2

Many terminal emulation programs will work if properly configured. In the following description, TeraTerm is used to establish the CLI 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 FAR labled COM 1

- 23 -

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.

-24 -

After completing the serial port changes, the user will be prompted for a user name and password. In dual band units each band is changed independently and requires an independent login. To make changes to the cellular band, the default user name is cellband. The pass-

word for both bands is csi1234. The user name for changing the PCS band is pcsband. After entering the password and pressing return the CLI main menu will appear. The actions displayed are self-explanatory. Pressing 1 will continue to expand this session screen and allow the following parameters to be set.

-25 -

Each Set Parameter selection, when chosen will be expanded to allow changing or setting of that parameter. 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.

- 26 -

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, this one for filter selection. 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 emula-

tion program for TCP/IP. As with the serial connection CSI suggests the use of TeraTerm. In the following description, again, 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 because it does vary somewhat with the operating system involved, this manual will not detail the procedure. If you require assistance, contact your IT department and they will be able to set up your PC for you. When the Tera Term 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.

- 27 -

Pressing the OK button will bring the user to the following screen, which will require the user to log in. In dual band units, each band is changed independently and requires an independent login. To make changes to the cellular band the default user name is cellband. The default user name for changing the PCS band is pcsband. In the field after the prompt DSP85-PCS-X login; type the user name for the band to be changed. The default password is csi1234 for both bands. After typing the password press the enter key and the main menu will be displayed as shown next.

- 28 -

Telnet and serial sessions both provide access to the same CLI interface. We have already shown many of the options available with the Set Parameters selection, so next you will find examples of the screens and options available when Get Parameters and System Commands are chosen.

- 29 -

The System Information selection will display the following screen. 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, it must be added to the repeater before site installation and operation. 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-CP. 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.
