- 2 -Product DescriptionCellular Specialties, Inc. (CSI) developed the LCD Model Bi-Directional Amplifier(BDA) for use in enclosed structures where sufficient signal from local cell sites tooperate cell phones was unavailable within the building. It is necessary that sufficientsignal be available on the roof of the structure. The BDA is connected to an externalantenna, usually on the roof, and to one or more internal antennas placed strategicallythroughout the area where phone service is desired.The external antenna is usually a directional type such as a “yagi”. Internal antennasare usually omnidirectional, although various other types may be used for certaininstallations. The BDA amplifies both the “uplink” (phone to tower) and “downlink”(tower to phone) signals thus facilitating communications to and from the local cellsite.There are seven amplification stages on the downlink and seven on the uplink for atotal of +62 to +80 dB nominal gain for each link. Gain can be set using the LCDdisplay and select/up/down switches. There are also LED indicators on the topcover for power overload and gain reduction to prevent oscillation.An automatic amplifier safety shutdown circuit isalso incorporated that will disable the transmit-ters should the uplink or downlink overloads bereached to prevent excessive intermodulation andoscillation. The amplifier will periodically attemptto recover from this condition.The BDA is equipped with an interface connector(RJ-15) designed for use with an optional remotemonitor. A second Connector (RJ-11) is used forremote monitoring and shutdown. The RJ-11pin-out is listed here.•Pins 3 & 4 will toggle from open to closedwith faults.•Pin 1 (5 Volts) can be tied to Pin 5 toshut the unit down.LED IndicatorsWarning: The unit has sensed instability due to insufficient isolationbetween the inside antenna and the outside antenna, and hasreduced the gain of the amplifier. This is done to prevent oscilla-tion, which can interfere with the handsets in the covered areaand/or the wireless service provider’s base station.Fault: The gain of the unit has been reduced to a minimum in order(Red) to prevent very strong input signals from overloading theamplifier. The amplifier will attempt to recover from this condi-tion, initially at fifteen second intervals and then at four-minuteintervals.Pin-Out ChartPin Description 1 5 Volts 2 Center Contact Alarm Relay 3 Alarm Contact-Open 4 Alarm Contact-Closed 5 Shut Down 6 Ground

FeedBack of this nature causes the amplifier to emit acontinuous signal of maximum amplitude and could, in some cases, interfere withnormal operation of the cell site. The use of window mounts or other non-rooftopmountings should be avoided.•The Installer should refer to the Safety Precautions, in the following section, forproper antenna selection and installationImportant Installation NotesWARNING! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF AHANDSET IS CONNECTED DIRECTLY TO THE BDA OR THE COAX THATLEADS TO THE BDA.Important Safety Information!For INDOORuse, an omni-directional antennawith a maximumgain of 3 dBi isauthorized for use with this unit.Inside antennas must be positionedto observe minimum separation of20 cm. (~ 8 in.) from all users andbystanders. For the protection ofpersonnel working in the vicinity ofinside (downlink) antennas, thefollowing guidelines for minimumdistances between the human bodyand the antenna must be observed.The installation of an INDOORantenna must be such that, undernormal conditions, all personnelcannot come within 20 cm. (~ 8.0in.) from any inside antenna.Exceeding this minimum separationwill ensure that the employee orbystander does not receive RF-exposure beyond the maximumpermissible exposure according tosection 1.1310 i.e. limits forGeneral Population/UncontrolledExposure.For OUTDOOR use, a directionalantenna up to a maximum gain of11dBd is authorized for use with thisunit.The outside antenna must bepositioned to observe minimumseparation of 120 cm. (~ 4 ft.) fromall users and bystanders. For theprotection of personnel working inthe vicinity of outside (uplink)antennas, the following guidelinesfor minimum distances between thehuman body and the antenna mustbe observed.The installation of an OUTDOORantenna must be such that, undernormal conditions, all personnelcannot come within 120 cm. (~ 4ft.) from the outside antenna. In allinstallations, the antenna shouldnever be mounted such that themain beam is directed toward anarea where workers or bystandersmay be present. Exceeding thisminimum separation will ensurethat the worker or bystander doesnot receive RF-exposure beyondthe Maximum PermissibleExposure according to section1.1310 i.e. limits for GeneralPopulation/Uncontrolled Exposure.
- 6 -Performance AdjustmentThe menu system can be navigated with five buttons: UP, DOWN, EDIT,SAVE, and MENU. Feedback is given to the operator through the LCD panel.The LCD Command Interface offers two distinct series of menus: the ViewMenu Series, which allow a user to view, but not alter, certain bits of data theunit maintains; and the Edit Menu Series, which permit the alteration of thisinformation. The Edit Menu Series are kept secure from general use by apassword, if password control is invoked, so that curious or malicious peoplecannot randomly alter data. However, this unit is shipped with this featuredisabled. See page 16 for further details.In both menu systems the MENU button is used to maneuver between menusin a sequential fashion. EDIT is generally used to enter the Edit Menu Series,and SAVE is generally used to exit it. (Pressing SAVE in all menus exceptthe one that allows you to alter the Edit BDA Name menu (explained below)will force any changes made while in the Edit Menu Series to be saved in non-volatile memory. The BDA will then exit the Edit Menu Series; if the userneeds to edit more information, they will need to press EDIT and enter apassword again.) The UP and DOWN buttons are usually used to scrollthrough options within a given menu, if several options exist.What follows is an exploration of each menu series in detail, and how eachmenu represents and interprets data.
- 7 -The View Menu Series Page 8Page 8Page 9Page 10Page 10Page 10Page 10Page 11
- 8 -Screen Saver DisplayUpon powering up the BDA, a display resembling this will appear on the LCDpanel:The first row contains the network name of the BDA; this allows the user todetermine which BDA they are looking at. This name can be changed towhatever the user desires, and can contain blank spaces, capital letters,lowercase letters, and numerals. It is limited to seven characters to facilitatecommunication with a Web Monitor, should one be desired.This screen is known as the Screen Saver Display because it is the screenthat the BDA will revert to showing if there has been no activity detected onthe keypad for at least ten minutes. If this occurs, the LCD backlight will shutoff to save power and prevent the backlight from burning out. Pressing anykey other than EDIT while in the Screen Saver Display will turn the backlightback on, and advance the menu to the Power Readout Display. Pressing theEDIT key will advance you to the EDIT menu series.Power Readings DisplayThis menu shows the instantaneous power readings in the BDA, as well aswhether or not the gain is being actively attenuated by Automatic GainControl.A typical Power Readings Display might appear as below:This shows that the composite power is currently 19 dBm on the output of theuplink pass band; 27 dBm on the output of the downlink pass band; andAutomatic Gain Control has attenuated the signal 2 dB on the downlink passband.It should be noted that when the power through a channel is less than 0 dBm,the display will show “<0” in the location where the reading usually appears.This prevents spurious power readings from occurring because of randomnoise.The UP, DOWN, and SAVE buttons have no effect in this menu. Pressing theMENU button, however, will advance the user to the Event Readout displays.
- 9 -Event Readout DisplaysThree performance measures are tracked within the BDA, and are recordedand displayed as events. Up to 999 of each type of event is recorded. If morethan this number of events are detected, the menu system will continue todisplay 999.A typical display might look like this:Three types of service affecting events that the BDA records can be viewedwithin separate windows. Pressing the MENU button will sequence throughthese displays. The first window in the sequence displays isolation controlevents, the next fan performance events, and finally abnormal temperatureevents. A fourth menu press will display a recording of the UL and DL peakpower.After a window has been bypassed, all windows selectable thru menu pressesmust be viewed in order to return to the last viewed display.Any event will cause a yellow (WARNING) LED to illuminate. The warningLED can be extinguished by resetting the appropriate event counter(s) via theEDIT menu or by cycling the primary power. Cycling primary power will resetthe counters as well. Events capable of being recorded are:•Isolation Control: This event is recorded whenever insufficientisolation exists between the Donor and DAS antennae. When thatcondition occurs, the Oscillation Event counter will be incremented.Oscillation control is implemented in the BDA control system. If anoscillation condition is detected, the BDA control circuitry will attemptto stabilize the system by immediately reducing the gain 3 dB. Awarning will also be immediately displayed that shows theaccumulated change on the affected link(s) e.g. [UL (003 dB attn).After a period of time, the system will recheck itself and continue toreduce the gain in 3 dB increments until the oscillation conditions nolonger exists. Each gain reduction is counted as an event. At somepoint, if stability cannot be reached, the BDA amplifier on the affectedlink will be shut down. After shutdown, or at any point after stability isreached, the system will attempt to fully recover lost gain. Until thesystem can recover to the original gain setting, the warning LED willremain illuminated.•Fan Limits: The BDA system firmware monitors fan performance. Ifeither fan speed exceeds specified limitations, a fan event will be
- 10 -recorded for each instance. A yellow LED will remain illuminated untilthe event counter is reset to zero. (This feature is not available infrimware version 1.1.0 and prior releases)•Over Temperature Limit: Amplifier junction temperature is monitoredcontinuously. If the temperature rises above a factory determinedlimit, an Overheat Event will be recorded. If the event is transitory,each excursion above the limit will increment the Overheat counter. Ayellow LED will remain illuminated until the counter is reset to zero.Event counters serve as diagnostic tools for maintenance and system healthassessments. Only isolation control will alter the intended performance of thesystem. Fan and Overheat events have no effect on the BDA.Pressing MENU within at this display will advance the user to the Peak PowerDisplay.Peak Power Readout DisplayThis display shows the highest readings that have registered on the BDAsince power-up or reset.A typical display might look like this:Note that since AGC cannot act instantaneously, the peak power seen on theoutput might be higher than the power the unit is capable of sustaining. Thisis not an error, but an indication that the power did exist – briefly – at theoutput port. This is meant to aid in diagnostics if necessary.Pressing the MENU button will advance the user to the Downlink Gain display.Gain DisplayThis display indicates the gain applied to the uplink or downlink pass band.These values might differ if an offset has been applied.A typical gain display might look like this:Pressing the MENU button will advance the user to the BDA Name Display.
- 11 -BDA Name and Address Display In addition to its name, a BDA can be uniquely identified on a network with aWeb Monitor by its name. The name here is identical to the one in theScreen Saver Display. The BDA name is limited to seven characters. EachBDA accesible by a single Web Monitor on the network must have a uniqueaddress within that network between one and seven, inclusive. This displayalso shows the current BDA’s network address.A typical BDA name and address display might look like this:Pressing the MENU button will return the user to the Screen Saver display.Note that pressing the EDIT button in any of these displays will cause theBDA to enter the EDIT menu series. A password will be requested from theuser if password control has been invoked. Successful password entries willpermit the user to enter the Edit Menu Series; unsuccessful entries will causethe BDA to revert to the Screen Saver display. The password menu does notbelong to either the View Menu Series or the Edit Menu Series. It is shownhere for completeness.A typical password entry display might look like this:Each password consists of a series of five button presses. None of thebuttons can be MENU. Pressing the menu button or entering an invalid keyin the password key sequence will cause an immediate exit to the ScreenSaver display. In order to keep the password masked as it is entered, thebottom row reveals how many keys have been entered in the password thusfar. In the example shown, then, three out of the five-key presses have beenreceived and validated. Regardless of which display the user was viewing priorto entering the password mode, successful password entry will take them tothe Edit Oscillation Events display.

- 13 -Edit Events Display These displays will show you the number of events recorded in each of threecategories (Oscillation, Fans, Overheat). Each MENU button press will moveto the next display. At any event category, pressing EDIT will clear thecounter and rest the number of events to zero.To indicate that you are currently in the EDIT series, the first word in the topline of the display will always be EDIT followed by the name of the display.A typical EDIT EVENTS display might resemble the following:.Edit Peak Power Readout DisplayThis display will show the same information indicated in the View MenuSeries, however, pressing EDIT clears the peak power readings and capturesthe current values.A typical display might look like this:Pressing MENU at this point will cause the BDA to enter the Edit DownlinkGain display.Edit Downlink Gain DisplayIn this window the downlink gain can be altered, however it cannot be adjustedlower than the difference between the calibrated maximum output minus 30dB (max gain -30 dB). The range of the attenuators in either the uplink or thedownlink imposes this constraint. Within that permissible range, the valuescan be changed in 1 dB increments by pressing the UP or DOWN keys. If anattempt is made to change the gain value beyond a 30 dB range, the value willincrement to the highest or lowest acceptable value depending on which endof the constraint the attempt is initiated.By example, for an 80 dB gain amplifier the minimum gain setting is 50 dB.Pressing the DOWN key when 50 dB of gain is currently being displayed willreturn gain setting to 80 dB. Likewise, if the gain setting is at 80 dB, pressingthe UP key will change the gain to 50 dB.Using another illustration, an amplifier having a maximum gain of 62 dB willhave a minimum gain setting of 32 dB.
- 14 -A typical downlink EDIT Display may look like this:The MENU button will take the user to the Edit Uplink Gain display.Edit Uplink Gain DisplayThis display is functionally identical to the Edit Downlink Gain dispaly, butalters the gain through the uplink pass band instead of the downlink passband.A typical uplink EDIT Display may look like this:Pressing the MENU key here will take the user to the Edit BDA Name display.Edit BDA Name DisplayThis display will let the user set a new name for the BDA for identificationpurposes on a Web Montior network. This also changes the name shown onthe Screen Saver display and the BDA Name display. A name can consist ofuppercase letters, lowercase letters, numerals, and/or blank spaces.A blinking cursor shows the user which letter they are editing; the editprocess is executed from left to right. In any cursor position, characters areselected by using the UP and DOWN buttons. Once the user has selectedthe letter for that position, SAVE will lock that letter into that position andadvance the cursor to the right. Pressing EDIT will back the cursor up onespace and permit the user to edit that letter again using the same process.One cannot back up beyond the first character. Pressing SAVE on theseventh character will cause the BDA to advance to the Edit BDA Addressdisplay, as will pressing MENU at any time. Pressing MENU, however, willcancel any changes that the user has made to the BDA name.A typical display for this menu might look like this:
- 15 -Example: In the above display the cursor shows that the user is at the fourthcharacter position. In the below display the user has used the UP and DOWNbuttons to select “S”. The cursor at that position will blink intermittently,alternating with the character currently stored at that position:Continuing the example, pressing UP at this point will illustrate theadvancement of the character at the current position to “T”:Edit BDA Address DisplayThis screen permits the setting of a new address for a BDA on a Web Monitornetwork. Valid values are from one to seven, inclusive. Care must be taken inthis menu not to set the address to that of another BDA on the same WebMonitor network.The different addresses permissible are presented in cyclical fashion.A typical display might look like this:Pressing UP and DOWN will scroll through the different valid addresses.Pressing MENU will exit to the next screen: the Software Shutdown display.Software Shutdown display A software shutdown will prevent the BDA from functioning and will cease dataacquisition by the BDA processor. There are only two modes available, andthey can be selected by pressing UP and DOWN: NORMAL, which is theregular form of BDA operation, and SHUTDOWN, which performs a softwareshutdown of the BDA.A typical display might look like this:Once the BDA is shut down through software, the FAULT (red) LED will glow.
- 16 -When the BDA operation mode is returned to NORMAL, the FAULT LED willextinguish.Pressing the MENU button at this point will cause the BDA to display theCreate New Password display.Create New Password DisplayThis display will allow the user to enter a new password. The display,however, will not be viewable until password control is invoked by first pressingthe proper keys simultaneously (EDIT and MENU). This operation will eitherenable the default password (UP, DOWN, DOWN, UP, UP) if no passwordchange has ever been implemented, or the current password. Eitherpassword sequence will be required to authorize a new password. PressingEDIT and MENU again will toggle the password off. This process will requirethe current password to complete the action.Pressing any button after a new sequence has been entered will cause thatsequence to be stored. Pressing MENU at any time during the sequence willabort the process and revert to the most recent password. If a change issuccessful, the new password will be required for future changes to beenabled.Password control cannot be disabled without authorizing the mode changeusing the current password.The change password process is much the same as the PASSWORD ENTRYprocess described earlier.The display that asks for the current password looks like this:Once this has been entered, the request for the new password looks like this:A password can only consist of the buttons UP, DOWN, and SAVE, sinceEDIT and MENU have global functionality.Pressing MENU will abort this and return to the Edit Events display.None of the changes invoked take effect unless the user presses SAVE.Once this input occurs, all changes are saved to non-volatile memory and the
BDA returns to the Screen Saver display. If the BDA does not detect any keypresses within ten minutes of the last key press, the BDA will discard allchanges made in the Edit Menu series since the last password entry andrevert to the Screen Saver display.Final Note: If the BDA should become unstable, and none of these menucommands are operable, the processor can be reset to factory defaults bypressing and holding the UP, DOWN, and MENU buttons simultaneously forone second. This is a catastrophic recovery measure and should not beimplemented unless all other procedures have failed.- 17 -
- 18 -TroubleshootingAll cables should be carefully checked for “shorts” and “opens”.The rooftop antenna, if directional, should be checked for proper alignment along thecalculated compass heading. Typically, the directional antenna should be aimed atthe same site that your handset uses in the area where the outside antenna isplaced.If cables and alignment are acceptable, it may be necessary to use a spectrumanalyzer to examine the signal environment in which the BDA is operating. Theexistence of strong analog signals within the frequency bands can cause the AGCto reduce the amplifier’s gain particularly on the downlink. In some cases additionalfiltering might be required to reject these unwanted signals. In some instances thedirectional outside antenna can be reoriented, horizontally to place the interferingsource in an antenna pattern “null”. There also may be some cases where theinterference from outside signals is so great that they can not be filtered or otherwisereduced or eliminated without expensive and possibly prohibitive measures. In thesecases it may not be practical to use the BDA for providing coverage at these sites.
