Product Description Cellular Specialties, Inc. (CSI) developed the LCD Model Bi-Directional Amplifier

(BDA) for use in enclosed structures where sufficient signal from local cell sites to operate cell phones was unavailable within the building. It is necessary that sufficient signal be available on the roof of the structure. The BDA is connected to an external antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where phone service is desired. The external antenna is usually a directional type such as a yagi. Internal antennas are usually omnidirectional, although various other types may be used for certain installations. The BDA amplifies both the uplink (phone to tower) and downlink

(tower to phone) signals thus facilitating communications to and from the local cell site. There are seven amplification stages on the downlink and seven on the uplink for a total of +62 to +80 dB nominal gain for each link. Gain can be set using the LCD display and select/up/down switches. There are also LED indicators on the top cover for power overload and gain reduction to prevent oscillation. LED Indicators Warning:

The unit has sensed instability due to insufficient isolation between the inside antenna and the outside antenna, and has reduced the gain of the amplifier. This is done to prevent oscilla-

tion, which can interfere with the handsets in the covered area and/or the wireless service providers base station. The gain of the unit has been reduced to a minimum in order

(Red) to prevent very strong input signals from overloading the amplifier. The amplifier will attempt to recover from this condi-

tion, initially at fifteen second intervals and then at four-minute intervals. Fault:

Important Installation Notes A high degree of isolation must be afforded to prevent any re-generative feedBack in the system. FeedBack of this nature causes the amplifier to emit a continuous signal of maximum amplitude and could, in some cases, interfere with normal operation of the cell site. The use of window mounts or other non-rooftop mountings should be avoided. proper antenna selection and installation The Installer should refer to the Safety Precautions, in the following section, for WARNING! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE BDA OR THE COAX THAT LEADS TO THE BDA. Important Safety Information

For INDOOR use, an omni-

directional antenna with a maximum gain of 3 dBi is authorized for use with this unit. Inside antennas must be positioned to observe minimum separation of 20 cm. (~ 8 in.) from all users and bystanders. For the protection of personnel working in the vicinity of inside (downlink) antennas, the following guidelines for minimum distances between the human body and the antenna must be observed. The installation of an INDOOR antenna must be such that, under normal conditions, all personnel cannot come within 20 cm. (~ 8.0 in.) from any inside antenna. Exceeding this minimum separation will ensure that the employee or bystander does not receive RF-

exposure beyond the maximum permissible exposure according to section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.

- 5 -

For OUTDOOR use, a directional antenna up to a maximum gain of 11dBd is authorized for use with this unit.The outside antenna must be positioned to observe minimum separation of 120 cm. (~ 4 ft.) from all users and bystanders. For the protection of personnel working in the vicinity of outside (uplink) antennas, the following guidelines for minimum distances between the human body and the antenna must be observed. The installation of an OUTDOOR antenna must be such that, under normal conditions, all personnel cannot come within 120 cm. (~ 4 ft.) from the outside antenna. In all installations, the antenna should never be mounted such that the main beam is directed toward an area where workers or bystanders may be present. Exceeding this minimum separation will ensure that the worker or bystander does not receive RF-exposure beyond the Maximum Permissible Exposure according to section 1.1310 i.e. limits for General Population/Uncontrolled Exposure. Performance Adjustment The 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 View Menu Series, which allow a user to view, but not alter, certain bits of data the unit maintains; and the Edit Menu Series, which permit the alteration of this information. The Edit Menu Series are kept secure from general use by a password, if password control is invoked, so that curious or malicious people cannot randomly alter data. However, this unit is shipped with this feature disabled. See page 16 for further details. In both menu systems the MENU button is used to maneuver between menus in 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 except the 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 user needs to edit more information, they will need to press EDIT and enter a password again.) The UP and DOWN buttons are usually used to scroll through options within a given menu, if several options exist. What follows is an exploration of each menu series in detail, and how each menu represents and interprets data.

Screen Saver Display Upon powering up the BDA, a display resembling this will appear on the LCD panel:

The first row contains the network name of the BDA; this allows the user to determine which BDA they are looking at. This name can be changed to whatever the user desires, and can contain blank spaces, capital letters, lowercase letters, and numerals. It is limited to seven characters to facilitate communication with a Web Monitor, should one be desired. This screen is known as the Screen Saver Display because it is the screen that the BDA will revert to showing if there has been no activity detected on the keypad for at least ten minutes. If this occurs, the LCD backlight will shut off to save power and prevent the backlight from burning out. Pressing any key other than EDIT while in the Screen Saver Display will turn the backlight back on, and advance the menu to the Power Readout Display. Pressing the EDIT key will advance you to the EDIT menu series. Power Readings Display This menu shows the instantaneous power readings in the BDA, as well as whether or not the gain is being actively attenuated by Automatic Gain Control. A typical Power Readings Display might appear as below:

This shows that the composite power is currently 19 dBm on the output of the uplink pass band; 27 dBm on the output of the downlink pass band; and Automatic Gain Control has attenuated the signal 2 dB on the downlink pass band. 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 random noise. The UP, DOWN, and SAVE buttons have no effect in this menu. Pressing the MENU button, however, will advance the user to the Event Readout displays.

- 8 -

Event Readout Displays Three performance measures are tracked within the BDA, and are recorded and displayed as events. Up to 999 of each type of event is recorded. If more than this number of events are detected, the menu system will continue to display 999. A typical display might look like this:

Three types of service affecting events that the BDA records can be viewed within separate windows. Pressing the MENU button will sequence through these displays. The first window in the sequence displays isolation control events, the next fan performance events, and finally abnormal temperature events. A fourth menu press will display a recording of the UL and DL peak power. After a window has been bypassed, all windows selectable thru menu presses must be viewed in order to return to the last viewed display. Any event will cause a yellow (WARNING) LED to illuminate. The warning LED can be extinguished by resetting the appropriate event counter(s) via the EDIT menu or by cycling the primary power. Cycling primary power will reset the counters as well. Events capable of being recorded are:

Isolation Control: This event is recorded whenever insufficient isolation exists between the Donor and DAS antennae. When that condition occurs, the Oscillation Event counter will be incremented. Oscillation control is implemented in the BDA control system. If an oscillation condition is detected, the BDA control circuitry will attempt to stabilize the system by immediately reducing the gain 3 dB. A warning will also be immediately displayed that shows the accumulated change on the affected link(s) e.g. [UL (003 dB attn). After a period of time, the system will recheck itself and continue to reduce the gain in 3 dB increments until the oscillation conditions no longer exists. Each gain reduction is counted as an event. At some point, if stability cannot be reached, the BDA amplifier on the affected link will be shut down. After shutdown, or at any point after stability is reached, the system will attempt to fully recover lost gain. Until the system can recover to the original gain setting, the warning LED will remain illuminated. Fan Limits: The BDA system firmware monitors fan performance. If either fan speed exceeds specified limitations, a fan event will be

- 9 -

recorded for each instance. A yellow LED will remain illuminated until the event counter is reset to zero. (This feature is not available in firmware version 1.1.0 and prior releases) Over Temperature Limit: Amplifier junction temperature is monitored continuously. If the temperature rises above a factory determined limit, an Overheat Event will be recorded. If the event is transitory, each excursion above the limit will increment the Overheat counter. A yellow LED will remain illuminated until the counter is reset to zero. Event counters serve as diagnostic tools for maintenance and system health assessments. Only isolation control will alter the intended performance of the system. Fan and Overheat events have no effect on the BDA. Pressing MENU within at this display will advance the user to the Peak Power Display. Peak Power Readout Display This display shows the highest readings that have registered on the BDA since power-up or reset. A typical display might look like this:

Note that since AGC cannot act instantaneously, the peak power seen on the output might be higher than the power the unit is capable of sustaining. This is not an error, but an indication that the power did exist briefly at the output port. This is meant to aid in diagnostics if necessary. Pressing the MENU button will advance the user to the Downlink Gain display. Gain Display This 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.

- 10 -

BDA Name and Address Display In addition to its name, a BDA can be uniquely identified on a network with a Web Monitor by its name. The name here is identical to the one in the Screen Saver Display. The BDA name is limited to seven characters. Each BDA accesible by a single Web Monitor on the network must have a unique address within that network between one and seven, inclusive. This display also shows the current BDAs 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 the BDA to enter the EDIT menu series. A password will be requested from the user if password control has been invoked. Successful password entries will permit the user to enter the Edit Menu Series; unsuccessful entries will cause the BDA to revert to the Screen Saver display. The password menu does not belong to either the View Menu Series or the Edit Menu Series. It is shown here for completeness. A typical password entry display might look like this:

Each password consists of a series of five button presses. None of the buttons can be MENU. Pressing the menu button or entering an invalid key in the password key sequence will cause an immediate exit to the Screen Saver display. In order to keep the password masked as it is entered, the bottom row reveals how many keys have been entered in the password thus far. In the example shown, then, three out of the five-key presses have been received and validated. Regardless of which display the user was viewing prior to entering the password mode, successful password entry will take them to the Edit Oscillation Events display.

MENU Edit Menu Tree This series of menus will allow the user to alter the information stored in the BDA. These menus are only accessible if the user has a password if password control is invoked. After getting into this sequence of menus, the user can save all changes made by pressing SAVE. Pressing this button exits the Edit menu Series however, so it is advisable to make all changes desired beforehand.

(The Edit BDA Name menu is an exception; refer to the documentation for details.) If no button is pressed within ten minutes of the last press, these menus will be exited and no changes made will be saved. Note the documentation to determine the function of the buttons in each of the menus. The password to enter the Edit Menu Series defaults to the following sequence until changed by the user:

UP, DOWN, DOWN, UP, UP Edit Events Display These displays will show you the number of events recorded in each of three categories (Oscillation, Fans, Overheat). Each MENU button press will move to the next display. At any event category, pressing EDIT will clear the counter and rest the number of events to zero. To indicate that you are currently in the EDIT series, the first word in the top line 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 Display This display will show the same information indicated in the View Menu Series, however, pressing EDIT clears the peak power readings and captures the current values. A typical display might look like this:

Pressing MENU at this point will cause the BDA to enter the Edit Downlink Gain display. Edit Downlink Gain Display In this window the downlink gain can be altered, however it cannot be adjusted lower than the difference between the calibrated maximum output minus 30 dB (max gain -30 dB). The range of the attenuators in either the uplink or the downlink imposes this constraint. Within that permissible range, the values can be changed in 1 dB increments by pressing the UP or DOWN keys. If an attempt is made to change the gain value beyond a 30 dB range, the value will increment to the highest or lowest acceptable value depending on which end of 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 will return gain setting to 80 dB. Likewise, if the gain setting is at 80 dB, pressing the UP key will change the gain to 50 dB. Using another illustration, an amplifier having a maximum gain of 65 dB will have a minimum gain setting of 35 dB.

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 Display This display is functionally identical to the Edit Downlink Gain display, but alters the gain through the uplink pass band instead of the downlink pass band. 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 Display This display will let the user set a new name for the BDA for identification purposes on a Web Monitor network. This also changes the name shown on the Screen Saver display and the BDA Name display. A name can consist of uppercase letters, lowercase letters, numerals, and/or blank spaces. A blinking cursor shows the user which letter they are editing; the edit process is executed from left to right. In any cursor position, characters are selected by using the UP and DOWN buttons. Once the user has selected the letter for that position, SAVE will lock that letter into that position and advance the cursor to the right. Pressing EDIT will back the cursor up one space and permit the user to edit that letter again using the same process. One cannot back up beyond the first character. Pressing SAVE on the seventh character will cause the BDA to advance to the Edit BDA Address display, as will pressing MENU at any time. Pressing MENU, however, will cancel any changes that the user has made to the BDA name. A typical display for this menu might look like this:

- 14 -

Example: In the above display the cursor shows that the user is at the fourth character position. In the below display the user has used the UP and DOWN buttons 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 the advancement of the character at the current position to T:

Edit BDA Address Display This screen permits the setting of a new address for a BDA on a Web Monitor network. Valid values are from one to seven, inclusive. Care must be taken in this menu not to set the address to that of another BDA on the same Web Monitor 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 data acquisition by the BDA processor. There are only two modes available, and they can be selected by pressing UP and DOWN: NORMAL, which is the regular form of BDA operation, and SHUTDOWN, which performs a software shutdown of the BDA. A typical display might look like this:

Once the BDA is shut down through software, the FAULT (red) LED will glow.

- 15 -

When the BDA operation mode is returned to NORMAL, the FAULT LED will extinguish. Pressing the MENU button at this point will cause the BDA to display the Create New Password display. Create New Password Display This display will allow the user to enter a new password. The display, however, will not be viewable until password control is invoked by first pressing the proper keys simultaneously (SAVE and MENU). This operation will either enable the default password (UP, DOWN, DOWN, UP, UP) if no password change has ever been implemented, or the current password. Either password sequence will be required to authorize a new password. Pressing EDIT and MENU again will toggle the password off. This process will require the current password to complete the action. Pressing any button after a new sequence has been entered will cause that sequence to be stored. Pressing MENU at any time during the sequence will abort the process and revert to the most recent password. If a change is successful, the new password will be required for future changes to be enabled. Password control cannot be disabled without authorizing the mode change using the current password. The change password process is much the same as the PASSWORD ENTRY process 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, since EDIT 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

- 16 -

BDA returns to the Screen Saver display. If the BDA does not detect any key presses within ten minutes of the last key press, the BDA will discard all changes made in the Edit Menu series since the last password entry and revert to the Screen Saver display. Final Note: If the BDA should become unstable, and none of these menu commands are operable, the processor can be reset to factory defaults by pressing and holding the UP, DOWN, and MENU buttons simultaneously for one second. This is a catastrophic recovery measure and should not be implemented unless all other procedures have failed.

- 17 -

Troubleshooting All cables should be carefully checked for shorts and opens. The rooftop antenna, if directional, should be checked for proper alignment along the calculated compass heading. Typically, the directional antenna should be aimed at the same site that your handset uses in the area where the outside antenna is placed. If cables and alignment are acceptable, it may be necessary to use a spectrum analyzer to examine the signal environment in which the BDA is operating. The existence of strong analog signals within the frequency bands can cause the AGC to reduce the amplifiers gain particularly on the downlink. 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 interfering source in an antenna pattern null. There also may be some cases where the interference from outside signals is so great that they can not be filtered or otherwise reduced or eliminated without expensive and possibly prohibitive measures. In these cases it may not be practical to use the BDA for providing coverage at these sites.
