Bi-directional Amplifiers 510 and 610 Series Preface Purpose The purpose of this document is to provide instructions to help the experienced technician/engineer install and commission an in-building wireless enhancement system using Westell Technologies Bi-Directional Amplifiers. Following the procedures outlined will minimize risks associated with modifying a live system and preclude service interruptions.
Bi-directional Amplifiers 510 and 610 Series There are no user-serviceable parts inside. Hazardous voltages are present when the cover is removed. Opening the chassis will void your warranty. If you suspect a malfunction with this product, call your dealer or Westell’s Technical Support line at 1-877-844-4274. It is recommended that the unit be powered down when connecting and disconnecting cables.
Bi-directional Amplifiers 510 and 610 Series 1 Overview 1.1 Product Information Westell developed the 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. Sufficient signal must 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.
Bi-directional Amplifiers 510 and 610 Series 1.1.
Bi-directional Amplifiers 510 and 610 Series 1.2 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 action prevents oscillation, which can interfere with the handsets in the covered area and/or the wireless service provider’s base station. Fault: The gain of the unit has been reduced to a minimum (red) to prevent very strong input signals from overloading the amplifier.

Bi-directional Amplifiers 510 and 610 Series 3 Installation Tips 3.1 Important Installation Tips A high degree of isolation must be afforded to prevent any re-generative feedback in the system. Feedback of this kind causes the amplifier to emit a continuous signal of maximum amplitude and could, in some cases, interfere with normal operation of the cell site. Avoid the use of window mounts or other non-rooftop mountings.
Bi-directional Amplifiers 510 and 610 Series 3.3 Troubleshooting Carefully check all cables for shorts and opens. Check the rooftop antenna, if directional, 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.
Bi-directional Amplifiers 510 and 610 Series 4 LCD Command Interface 4.1 Command Interface Overview 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, the data maintained by the unit. The Edit menu series permits the alteration of this information.

Bi-directional Amplifiers 510 and 610 Series 4.2.1 Screen Saver Display Upon powering up the BDA, a display resembling Figure 4-2 appears on the LCD panel: Figure 4-2: Screen Saver Display The first row contains the network name of the BDA; this allows the user to determine which BDA they are viewing. This name can be changed to whatever the user desires and can contain blank spaces, capital letters, lowercase letters, and numerals.
Bi-directional Amplifiers 510 and 610 Series 4.2.3 Event Readout Displays Within the BDA, three performance measures are tracked, 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. Figure 4-4 shows a typical display: Figure 4-4: Events Readout Displays Three types of service-affecting events that the BDA records can be viewed within separate windows.
Bi-directional Amplifiers 510 and 610 Series 4.2.4 Peak Power Readout Display The Peak Power Readout display shows the highest readings that have registered on the BDA since power-up or reset. Figure 4-5 shows a typical display. Figure 4-5: Peak Power Readout Display NOTE Because the AGC cannot act instantaneously, the peak power seen on the output might be higher than the power the unit is capable of sustaining.
Bi-directional Amplifiers 510 and 610 Series Figure 4-7 shows a typical BDA name and address display. Figure 4-7: BDA Name and Address Display Pressing the Menu button returns to the screen saver display. NOTE Pressing the Edit button in any of these displays causes the BDA to enter the Edit menu series. A password is requested from the user if password control has been enabled.
Bi-directional Amplifiers 510 and 610 Series 4.3 The Edit Menu Series The Edit Menu Series depicted in Figure 4-9 allows the user to alter the information stored in the BDA. These menus are only accessible if the user has a password and if password control is enabled. After entering this sequence of menus, the user can save changes by pressing Save. Pressing this button exits the Edit Menu series, so it is advisable to make desired changes beforehand.
Bi-directional Amplifiers 510 and 610 Series 4.3.1 Edit Events Display Edit Events displays show the number of events recorded in each of three categories: oscillation, fans, and overheat. Each Menu button press moves to the next display. At any event category, pressing Edit will clear the counter and reset 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 is Edit, followed by the display name.
Bi-directional Amplifiers 510 and 610 Series Figure 4-12 shows a typical Edit Downlink Gain display. Figure 4-12: 12: Edit Downlink Gain Display The Menu button takes the user to the Edit Uplink Gain display. 4.3.4 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. Figure 4-13 shows a typical uplink Edit Display.
Bi-directional Amplifiers 510 and 610 Series Figure 4-14 shows a typical display for the Edit BDA Name Display menu. Figure 4-14: 14: Edit BDA name display menu In Figure 4-14, the cursor shows that the user is at the fourth character position. In Figure 4-15, the user has pressed the Up and Down buttons to select S.
Bi-directional Amplifiers 510 and 610 Series 4.3.7 Software Shutdown Display A Software Shutdown will prevent the BDA from functioning and will cease data acquisition by the BDA processor. By pressing Up and Down, the user can select one of two available modes: normal, which is the regular form of BDA operation, and shutdown, which performs a software shutdown of the BDA. Figure 4-18 shows a typical Software Shutdown display.
Bi-directional Amplifiers 510 and 610 Series Figure 4-20 shows the request for the new password. Figure 4-20: 20: New password display A password can only consist of Up, Down, and Save, since Edit and Menu have global functionality. Pressing Menu will abort this and return to the Edit Events display. No changes take effect unless the user presses Save. After pressing save, all changes are saved to non-volatile memory and the BDA returns to the screen saver display.
