FIBER OPTIC MICROCELL SYSTEM EkoCel 1.0 PRODUCT DESCRIPTION The EkoCel™ Fiber Optic Microcell System will support CDMA, PCS 1900, IS-136 or AMPS system formats. EkoCel provides system coverage enhancement by remoting the base station RF receive and transmit via a fiber optic connection to a location requiring coverage. EkoCel is designed to meet or exceed applicable base station and FCC emission standards. The EkoCel enhanced specifications provide minimal impact to the overall system performance.
channelization to prevent the amplification and re-radiation of unwanted signals. Alarm reporting is accomplished at the hub not at the remote unit, which would require a subscriber phone or telephone modem to be mounted in a harsh environment that they are not typically designed for. 2.0 8 EkoCel FIBER OPTIC MICROCELL SYSTEM BLOCK DIAGRAM CI Wireless Inc. 1211 Ira E.

8. Software Controls 8.1.1. BASIC INTERFACE, Microcell (Remote) The interface of the EkoCel is based on a 12 key system with a 2x20 LCD screen. While a user is not engaged in any system functions the controller is in a RUN MODE. By that meaning the controller does most of its work while running outside of the user menus. The 12 key interface is designed around the functions the controller performs continually. The key lay out and functions of the keys are listed below.
8.1.2. SYSTEM SETUP on MICROCELL UNIT CONTROLLER Setting up the Microcell unit is done in one of two ways, Manual setup or Auto setup. A. Manual Setup During the initial startup of the Microcell the very first menu prompt to be encountered is the setup menu. By pressing the UP or Down key you can either select the manual or the auto setup. After choosing the correct setup method simply press the MENU key to continue with setup.
displayed, that menu screen MUST be changed (by pressing the MENU key) in order for the change to take effect remotely. The display will now read “UL Updating Please Wait..” When the update is complete the display will automatically change to reflect the Value at which it is set. Due to network latency, it may take up to 20 seconds to change the display. Setting the peak power limit is done here.
E. Date & Time Only the supervisor’s password has access to this feature. To flip between setting the time or the date, press the ITEM key. The FIELD key changes the digit to be edited and again the arrow keys change the digit. Press the MENU key to enter when finished. F. Event History Log The event history log will store the last 50 events that took place on both the microcell and hub side of the network.
8.1.4. ALARMS on MICROCELL UNIT CONTROLLER A. Viewing To view alarms currently alarming simply press the F2 key from any menu, or if not engaged in a menu press the ADD key then press F2. After viewing, press DEL to return to normal functioning. To return to menu items simply press the Menu key. To view the alarm history log, enter menus and press the menu key until the “Event History…..View log?” is displayed, then select Yes using the Up or Down arrow and enter by pressing the menu key.
8.2.1. BASIC INTERFACE of HUB UNIT CONTROLLER The interface of the EkoCel is based on a 12 key system with a 2x20 LCD screen. While a user is not engaged in any system functions the controller is in a RUN MODE. By that meaning the controller does most of its work while running outside of the user menus. The 12 key interface is designed around the functions the controller performs continually. The key lay out and functions of the keys are listed below.
8.2.2. SYSTEM SETUP ON THE HUB CONTROLLER Setting up the hub unit is done in one of two ways, Manual setup or Auto setup. A. Manual Setup During the initial startup of the Hub the very first menu prompt to be encountered is the setup menu. By pressing the UP or Down key you can either select the manual or the auto setup. After choosing the correct setup method simply press the MENU key to continue with setup.
8.2.3. USER SETTINGS on HUB CONTROLLER A. Accessing User Menus Hub - to access the user menus first the ADD key must be pressed. Due to background functions operating sometimes you may have to hold the ADD key for nearly a second. The result will be the Password Entry Screen. In order to proceed to other menus a valid password must be entered. The controllers are delivered with a set of factory passwords. The factory passwords can be altered by using the supervisor password only.
D. Maintenance Menu This set of menus contain many readings that will be useful during the calibration and or trouble shooting after problems occur. Some of these readings update in real time, but most are network related an update every 20-30 seconds. . If changes occur to the readings the user will NOT see them unless the Item key is used to scroll around back to it, then the value will be updated. If the second is true and the remote is not installed, ANY information displayed will be invalid.
G. Set New Password Only the supervisor’s password has access to this feature also. While it is possible to access this menu from the Microcell unit, the changes made will be reset through to the network standard within 20 seconds. This menu is only functional at the hub. The following are preset passwords: Supervisor - 21314, Tech 1 - 11311, Tech 2 - 11312, Tech 3 - 11313, Tech 4 - 1000 H.
8.2.4. ALARMS on HUB UNIT CONTROLLER A. Viewing To view alarms currently alarming simply press the F2 key from any menu, or if not engaged in a menu, press F2 after pressing the ADD key. After viewing, press DEL to return to normal functioning. Return to menu items by simply pressing the Menu key. To view the alarm history log, first enter menus and press the menu key until the “Event History…..View log?” Select Yes, using the Up or Down arrow and the menu key. The alarms will be displayed in log format.
8.3 RS 232 Port Communications. A. Hyper Terminal Connection To use the hyper terminal capabilities of the EkoCel™, you must have the enclosed adapter attached to the controller. If no adapter was included please contact the factory for replacement. This part # is 900-1000-072, consisting of the D-Sub/9 Pin Adapter, 6’ of cable and a RJ-12 connector.

Section 9. Installation INSTALLTION OF THE EKOCEL 1.9 FIBER OPTIC MICROCELL: NOTE 1: Installation and system set up should only be performed by qualified technicians. The user is cautioned that modification or changes to this device not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. NOTE 2: Manufacture's rated output power of this equipment is for single carrier operation.
Using the 1-meter fiber optic jumpers provided connect the Hub optical unit to the WDM Hub-FO Input to WDM-1310 - FO Output to -1550 Fiber Optic link cable will connect to WDM connection marked FC/APC . DANGER: INVISIBLE LASER RADIATION AVOID DIRECT EXPOSURE TO BEAM. -Apply Power and follow set up instructions. 9.4 IMPORTANT! Before performing maintenance on any internal module, make sure power is OFF.
9.5.1 Down Link Set Up for EKO-8R System Down Link set up for an 800MHz system may be completed with any known number of RF channels transmitting. Determine the proper output power level. Display, * Readings/Controls: Adjust base station input power to TX PWR IN. 800R Number of Total Active System RF Channels 1 2 4 8 16 32 Output Power Per Channel dBm Watts 47 50 44 25 41 12 38 7 35 3 32 1.
9.5.2 Up Link System Set Up for the System Up Link system set up for the system: The gain at the remote is a fixed at maximum this prevents system level changes from effecting the system noise figure at any optical path loss up to 20 dB RF loss. Adding attenuation at the hub makes UL system level adjustments. The RF modem detects the up link modem carrier RSSI level and adjustments are made using this pilot carrier as a reference. (RSSI level is updated once every 10 seconds).
