Product Description Cellular Specialties, Inc. (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.
LED Indicators Automatic safety precautions are built into the amplifier system. As a catastrophic response, a shutdown circuit is incorporated that will effectively disable all emissions should the uplink or downlink be overdriven or should an oscillation event occur. The amplifier will periodically attempt to recover from the detected condition based on time and various system measurements performed automatically. Warning light indicators are as follows: Warning: Indicated by a yellow LED.
EIA232 Pin Specifications USB Interface The Universal Serial Port (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. Ethernet The Ethernet AUI conforms to IEEE 802.3 and is capable of supporting 10/100 Mbps communication speeds. Monitoring & Alarms There are no physical connections provided to specifically communicate system states or alarm status.

Installation: Example: Standard Single Internal Antenna System Design Optional Accessories Accessories are available directly from Cellular Specialties, Inc. or any of CSI’s distributors. • Outside Gain Antenna PCS – model number (Tessco Part No. 59090) • Inside Omnidirectional Antennae PCS – model number (CSI-AS/1.85-1.99/2) SMR – model number (CSI-AS/806-866/4) Tri-Band – model number ( CSI-AO/800/2.
Important Installation Notes • Inadequate isolation between the outside and inside antennae may cause re-generative feedback in the system. Without a detection and control mechanism, 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.
LEDs on the top panel provide 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.

Performance Adjustment Warning Event Yellow LED Primary Power LED FACTORY DEFAULT SCREENSAVER Critical Event Red LED Keypad System The performance menu system can be navigated with five keypad buttons: UP, DOWN, SOFT KEYS, and ESC as shown above. There are two soft keys located either side of the UP/DOWN keys which have functional assignments based upon the menu option being displayed. Feedback is given to the operator through the PLED display panel used to form an information window.
The purpose of the initial menu scheme is to provide a quick overview of current system settings and values. The View Menu Series flowchart presented on the next page outlines the sequence of this information. Notice that no soft keys are available while in this menu loop. View Menu Series Content of the view menu series is described below along with an example snapshot of the actual window displayed. A high level overview is provided as an explanation of the function(s) offered through the window.

Filters The filters display shows the filter currently in use by the FPGA and stored in the EEPROM as either filter #1 or #2. Selecting the opposite filter from the FPGA will invoke that new configuration. Filters are given meaningful names to the extent possible. In the example above, “Full_100T” implies full spectrum using 100 DSP filter taps. GAIN The gain represented in this view menu screen represents net system gain in the downlink or uplink paths as selected from the configuration menu.
Current Event An overrange event is an indication of either uplink or downlink A/D converters being overdriven. The displayed window will indicate a date and time when the event occurred, or if no event occurred, indicate that condition as well. While the event is occurring, a red LED will illuminate and extinguish automatically after the event has ceased. The yellow LED will remain illuminated until reset from within the configuration Menu.
Show ID The show ID set of sub-menus is designed to access specific information about the device. Pressing select from within the this screen will allow access to model, serial number, software version, & IP address. The following windows show the format of this sub-menu information: The displayed number represents CSI’s internal item number.
. Display Events The Show Events window will allow access to more information about events that have triggered an alarm and set the yellow front panel LED to “ON”. The yellow LED can be reset from within the sub-menu shown below. The event that triggered the alarm will register a date-time group, specify the exact event and link, and allow it to be reset by scrolling through and viewing the event.

Appendix B Communication Protocol EIA Specification Note: The above diagram is provided as additional reference should adaptation be required.
Telnet Session(Remote Access) Remote access to the repeater can be gained thru a LAN connection using Telnet, a terminal emulation program for TCP/IP. Any terminal emulation program will work if properly configured. In the following description, “Tera Term” is used to establish the telnet session. This program is readily available via the internet and is free from Ayera Technologies at: http://www.ayera.com/terayerm/download.htm When the program is started, the following screen is displayed.
A successful login will provide the following screen: Set Parameter Commands The four actions displayed are self-explanatory. Pressing “1” will continue to expand the session screen and allow the following SET parameters to be entered. Each “Set parameter” can be expanded to gain access to the information category described.
“System Type”(1) selects whether the unit is PCS or Cell enabled. The selection must match the hardware; PCS hardware cannot be made to operate at cellular frequencies. (m) will move up one level. “Filter Programming” (2) displays the filter files that have been stored into memory. Each file contains the coefficients necessary to program the FPGA such that its response produces the desired passband.
“User Gain”(3) will offer downlink and uplink as choices. Selecting either link will display the current gain and offer the opportunity to change the gain on that link. 85.00dB is the example used. Inserting the same or different gain setting will move the menu up one level. “Calibration”(4) will offer a set of system calibration commands. These commands are used to calibrate the unit at the factory or at a facility having proper test equipment.
“Local Network”(5) will allow local network access to be enabled (1) or disabled (2). The network must be enabled thru a Command Line Interface (CLI), otherwise known as the console interface, if said network is disabled. This interface is accessed thru serial port “Com1”. “Remote Network Configuration”(6) can be used to establish remote access thru a modem installed in the unit.
“Idle Message”(7) refers to the screensaver message displayed after the keypad has been idle for a period of time. A default screensaver is stored in the unit to speed intial identification of the hardware capabilities. After installation, it may be desirable to provide the unit with unique network identification. “Diagnostics”(8) offers a list of tools used to determine the health of the system. AGC (1) will allow the AGC to be turned “OFF” or “ON”.
Filter Select (3) will allow the filter to be set from parameters loaded into EEPROM #1 or #2. Additionally, three specialized functional tests can be invoked. Hardware initialization (4) is equivalent to a soft re-boot. PA Output Control (5) allows the PA to be enabled or disabled. Actually, the gain is reduced to an insignificant level. Fan/Temp Control (6) allows the fan and temperature control settings to be manipulated. Get Parameter Commands Pressing “2” will provide access to GET commands.
“Link Parameters” (2) will likewise provide a snapshot view of the parameters used on both the Up and Down links.
“System Events” (3) This command will list the events that have occurred over time. Up to 100 descriptions and system times will be displayed with the oldest event falling off the register as a new event occurs (LIFO). The events register will initially not show any events until the list command is used. The clear command can be used to clear the register for fresh iinformation if desired.
“System Information” (4) can be used to get high level information about the system such as F/W version and assigned IP address. System Commands System commands are self-explanitory. Precaution should be taken not to invoke a USB Software Upgrade or Software Restore unless a USB key is installed. If this mistake occurs, the Telnet session will lock up and further commands will not be recognized until the unit is switched off and then on to force a hard re-boot, or the proper USB key is inserted.
Re-booting the system (r) will disconnect the session. Login must be reinitiated after the system has had time to reinitialize. Shutting down the system(s) will require the system to be switched off and then on agaiin in order to re-start the system. This cannot be accomplished remotely. Command Line Interface (Local Access, Non-login) Local access to the Command Line Interface (CLI), also known as the console interface, is made through com port 1 using a null modem serial cable.
After completing the serial port changes, a blank screen will appear. After pressing return the first CLI dialog will begin. No login sequence is required as in the LAN port telnet session. It is assumed the physical security of the port is adequate. Note: Graceful session termination is important. Use Disconnect under the file drop-down menu to terminate a session, otherwise the port may become disabled and force the system to be rebooted.
Once a connection has been established, the following Login screen is presented: The login will be echoed back to the terminal screen, however, as in all cases the password response is not echoed. The menu screens presented in the modem interface mode are identical to the previous two modes.
