After November 1, 2014, operation of an existing, unregistered Class B signal booster will be unauthorized and subject to enforcement action. Any new Class B signal booster installed after November 1, 2014 must be registered prior to operation. To encourage compliance with this new requirement, registration will be free of cost to the operator and/or licensee.[R11], [R9] FCC Part 90 Class B Signal Booster Registration & Discovery website: https://signalboosters.fcc.gov/signal-boosters/ Introduction There are three major components to the Tower-4 system; the Head-End hardware, the Distributed Antenna System (DAS) hardware, and the Site-Wide Network (SWN). Signals from the SWN are input to the Downlink (DL) Head-End (HE) hardware. These signals are filtered and amplified by the HE DL, and fed into the DAS. Signals from the DAS are input to the Uplink (UL) HE hardware. These signals are filtered and amplified by the HE UL, and fed into the SWN. There are two equipment rooms in Tower-4, and each equipment room has an Uplink and Downlink rack. One each of these racks (one UL and one DL) will be tested. The Downlink Rack contains three DSP Card Cages, two Dual Amplifiers, one Single Amplifier, and one CBC chassis. The signals are combined in the CBC chassis and fed to the DAS. The Uplink Rack contains three DSP Card Cages and one CBC chassis. Signals from the DAS are input to the CBC chassis. The UL and DL Channel Cards are the same design. They are FPGA-based designs, programmed essentially as active digital filters. The cards have a standard line-up; Analog-to-Digital Conversion, Digital Demodulation to baseband, digital filtering in the FPGA, Digital Modulation back to the original carrier frequency, and Digital-to-Analog conversion. The DSP Channel Cards can be programmed for multiple filters to process multi-carrier signals. Head-End Downlink Group There are eleven SWN windows (seven 400 MHz and four 800 MHz) input to the HE channel cards. Each window is input to a separate card; each card is set for one wide-band filter to pass multi-carrier signals, and is set for a specified gain. Wide-band filters for the DL are specified to achieve the required Group or Propagation Delay of 10 μs. The Site Wide Network (SDN Demarc) provides a constant level of -10 dBm per carrier into each Downlink Channel Card. The outputs of the Downlink Channel Cards are input to power amplifiers, either directly or via a combiner. Window groupings to the power amplifiers are shown on the system block diagrams. The gain of the Downlink Channel Cards are set to have an output of +20 dBm per carrier (100 mW) at the output of the power amplifiers, with -10 dBm per carrier at the input of the Downlink Channel Cards. The 800 MHz Downlink Channel Cards are set to have an output of +22 dBm at the output of the power amplifiers. The power amplifiers are very linear and can handle multiple carriers. The ALC (Automatic Level Control) of each amplifier is set to provide a maximum of +37 dBm (5W). The outputs of the 400 MHz and 800 MHz power amplifiers are combined through combiners and low-loss CBC (CrossBand Couplers). The output of the CBC is the connection into the DAS. Head-End Uplink Group There are eleven windows (seven 400 MHz and four 800 MHz) input to the UL channel cards from the DAS. Each window is input to a separate card; each card is set for one or more narrow-band filter to pass multi-carrier signals. Narrow-band filters for the UL are specified to achieve the required Group or Propagation Delay of 25 μs. A group of frequencies (window grouping) is assigned to one Uplink Channel Card. The signals coming from the DAS are amplified with an LNA (low-noise amplifier) and distributed to the Uplink Channel Cards using a CBC and splitters. The Uplink Channel Cards will receive multi-carrier signals in the range of -83 dBm to -33 dBm per carrier. Each Uplink Channel Card uses AGC (Automatic Gain Control) to maintain an output level of -33 dBm. The Site Wide Network or SDN Demarc requires no more than -33 dBm per carrier.

The filter parameters of each channel can be independently selected to optimize the Adjacent Channel Time Delay Interference (TDI). The FPGA-based design allows for the implementation of a number of Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) filters, including Cauer, Butterworth, and Tchbecheff. All filters can be configured with the number of poles required to provide optimum rejection, within the constraints of bandwidth and filter roll-off, to reduce or eliminate TDI. Model 1465DSP is a two slot solution to channelized filtering for DAS systems. Two slot receptions enable the filtering, AGC and Key Line control in two 12.5 kHz channels on one channel card. TDMA and FDMA formats can be supported. Parameters are adjustable using a Graphical User Interface (GUI) that runs on a laptop tied to the USB front panel connector. The GUI enables the setting of center frequency, bandwidth, threshold of operation, and Keying (CD, PL, or DPL). All channel parameters are stored in non-volatile memory and the board will power up in the last programmed configuration. The GUI will run on any laptop under Windows XP or later versions.

The unit is a single or dual-amplifier configuration. Each amplifier has its own processor board, alarms, panel indicators and power supply. The processor board controls the enable signal to the amplifier and monitors forward power, reverse power, current, fan status and heat sink temperature. The processor board features remote monitoring capability via Ethernet. A computer running the Graphical User Interface (GUI) can display the status of the amplifier and provide control. A front panel Look Port for each amplifier allows the user to sample the signal at the front panel. Look port enables measurement without interrupting main line communications. The Look Port sample is 40 dB below the main RF output port. The processor board contains six NO/NC relay lines that interface to any alarm system and control.

Back to Index NMS User’s Manual Page 4-10 Appendix B RACS (Radio Access Control System) Description There are two equipment rooms in Tower-4, and each equipment room has an Uplink and Downlink rack. The Downlink Rack contains three DSP Card Cages, two Dual Amplifiers, one Single Amplifier, and one CBC chassis. There are a total of eight processor boards in the Downlink rack; one board in each Card Cage, two boards in each Dual Amplifier, and one board in the single amplifier. The CBC chassis is passive and does not have a processor board. The Uplink Rack contains three DSP Card Cages and one CBC chassis. There are a total of four processor boards in the Uplink rack; one board in each Card Cage and one board in the CBC chassis. Each processor board has an Ethernet interface and is connected to an Ethernet Switch in the associated rack. Each processor board also has six relays that are the interface to the RACS system. There are three wires associated with each relay; Common (COM), Normally Open (NO), and Normally Closed (NC). There is a DB-25F connector on each front panel that brings out the eighteen lines; three lines per each of the six relays. A relay changes state from NO to NC if a corresponding fault is detected by the processor board. The threshold for each fault function is programmable via the Graphic User Interface (GUI) program provided with the system. Five block diagrams are attached: Figures 1 and 2 are high-level block diagrams showing the components of the system that implement the RACS function for the DL and UL racks respectively. Each of the components described above is listed along with the corresponding AMDI model number. Figures 3, 4, and 5 show the RACS section of a typical Card Cage, DL Power Amplifier, and UL CBC in more detail. DSP Window Card RACS Interface The Card Cage chassis has a backplane board that runs across the back of the chassis. The DSP cards and the processor board plug into the backplane, which provides the signal path for an RS-422 interface between the processor board and each of the DSP Window cards. The processor board sends command to, and receives status from, each of the DSP Window Cards. Status messages from the Window card to the processor board include; Forward Power, Reflected Power, Current, Temperature, Mode (narrow-band or broadband), and number of active channels. Since there is one processor board per chassis, there is one set of six RACS relays per chassis. The relays represent the composite status for the (three or four) DSP cards in the chassis. Any one of the following faults on a channel card will result in the relay corresponding to that card changing state: Forward Power Fault, Reflected Power Fault, Current Fault, Temperature Fault. The following is a list of relay fault assignments: DSP Channel Card #1 Fault DSP Channel Card #2 Fault DSP Channel Card #3 Fault DSP Channel Card #4 Fault Spare #1 Spare #2 Figure 3 shows the Card Cage block diagram and the RACS relay lines. Power Amplifier RACS Interface The Power Amplifier chassis contains either one or two power amplifier modules. A power amplifier module consists of a power supply, power amplifier, optional combiner, and processor board. Figure 4 shows the lines between the amplifier module and the processor board. Voltages proportional to amplifier forward and reflected power are input to the processor board. ALC level, ALC enable, and amplifier enable (key line, to turn the amplifier on and off) are output from the processor board to the amplifier. In addition to these signals, the processor board monitors amplifier current (via a sense resistor in series with the power supply) and amplifier temperature (via a thermistor mounted to the amplifier heat sink). A tachometer signal on the fan is monitored to ensure the fan is rotating. The processor board sends command to, and receives status from, the amplifier and peripherals (current, temperature, and fan status). The following is a list of relay fault assignments: Forward Power Fault Reflected Power Fault Over-Current Fault Temperature Fault Fan Fault Spare Uplink CBC RACS Interface The Uplink CBC chassis contains a Cross-Band Coupler, two Splitters, and two LNA’s. There is one processor board in the chassis that measures power supply current into each LNA. The following is a list of relay fault assignments: LNA #1 Over-Current Fault LNA #2 Over-Current Fault Spare #1 Spare #2 Spare #3 Spare #4 Notes: 1.RACS fault thresholds are the same as for the chassis front-panel LED’s. Thresholds are set using the AMDI GUI. 2.The “Forward Power” fault is not defined at this time. 3.All faults are generated under firmware control of the processor board in the corresponding chassis. These can be re-defined in later firmware versions.

To use the WTC GUI connect a USB cable from the PC to a DSP module and start the program by double-clicking on the desktop shortcut that looks like this: When the WTC GUI program starts it looks for DSP modules on the USB interface. If it finds only one module on the USB port, it displays a dialog box like the following one to announce on which USB COM port it has found a DSP module on. Clicking the OK button dismisses the COM port dialog box. On the other hand if it finds more than one the program lets the user select which module to work with. Next the WTC GUI program reads the current settings from the DSP module and also the module board ID, serial number, and the revision dates of the GUI, firmware and settings. It displays that information in an About dialog box like this: The About dialog, is displayed on top of the main GUI window. Here is an example of the Main window for one of the WTC uplink modules, namely ULW8 (Up Link Window 8): The settings that were read from the non-volatile memory on the DSP module allow the GUI program to configure the GUI controls so they match the DSP module. The settings include the selected mode which may be either “single channel low delay mode” which is normally used for the downlink or “multiple channel narrowband mode” which is usually used for uplink. The WTC firmware allows up to eight channels in uplink mode but other firmware is available from AMDI that allows up to sixteen channels per DSP module. The ULW8 has six channels. The GUI hides the GUI controls for the channels beyond those six since the settings read from the board tell the GUI program that for the “Up Link Window 8” module only six channels are used. To use a different number of channels the user only needs to change the number in the edit box labeled “# of Channels”. As you can see in the figure above, for each channel the GUI provides controls that specify these values: Channel Frequency (MHz) Channel filter bandwidth Channel filter order Output AGC setpoint (dBm) Squelch A and B types Squelch A and B values The GUI also provides the following outputs: Squelch A and B ON or OFF indicators Channel Input signal level (dBm) Channel Output signal level (dBm) Here is an explanation of some of these settings. Each channel uses Digital Signal Processing to implement very flexible filters. The user can control both the filter bandwidth and the filter sharpness and time delay. The filter bandwidth is selected using this control: The filter sharpness and time delay are related. Sharper filters have a longer time delay. Time delay is important in applications in which a receiver may receive both the signal that has passed through the re-broadcast equipment and the signal directly from the transmitter. The following control lets the user select the filter order which is a measure of the filter’s sharpness. For each channel this control lets the user select the filter order: A filter with an order of 6 provides an input to output delay of about 24 microseconds but the filter transitions from its passband to its stop bands slowly. A filter with an order of 80, on the other hand has sharp edges but a longer delay. Each channel has two squelch circuits because in some applications two different services share the same frequency channel. In other cases more than one service are so close in frequency that a single re-broadcast channel is used to handle both. For both Squelch A and Squelch B the user can select using one of the two “Squelch Type” controls like these: As the user changes the “Squelch Type” the prompt for the “Squelch Value” edit box changes. For Carrier squelch type it reads “Squelch A Level (dBm):” as shown for ULW8 channel 2. For “PL CTCSS” squelch type it reads “Squelch A Tone Freq (Hz):” as shown for ULW8 channel 0. For “DPL DCS” squelch type the prompt is “Squelch A DPL Code:” Notice, in the ULW8 figure above, that for channel 2 there is green text that reads “A is ON” and red text that reads “B is OFF”. That text lets the user see the current output of each of the channel’s two squelch circuits. When either Squelch A or Squelch B is ON then the channel is keyed on. When it is keyed on the output level text for the channel indicates the output level in dBm. The input level text for each channel shows the level of the signal that has passed through the channel’s filter. The ULW8 screen capture was done while there was a signal within that channel at about -53 dBm. The edit box just to the right of the “Output Setpoint (-dBm):” text lets the user specify the desired output signal level (at the DSP module’s output) for each channel that is “Keyed ON” by the squelch circuits. The description so far has been focused on “Up Link, Multiple Narrowband Channels” mode. In that mode the time delay is less critical. The signal path is from the portable radio in the building to the distributed antennas through the DSP modules, combiners and amplifiers through fiber optic links to the communication HUB. So there is very little chance that the receiver located distant from the portable at the hub will receive both the signal directly from the portable and through the channelized re-broadcast system. In this case the filters can be selective so they pass only one or two radio channels each even though this higher selectivity comes at the price of increased time delay. The filter order control described above lets the user trade off filter selectivity for time delay for each channel. For downlink the signal path is from transmitters at the communication hub is via fiber optic cables through the DSP modules to 5 watt amplifiers to transmit on the distributed antenna system that runs up both stairwells. Since some of that transmitted signal and a signal directly from the transmitter may be received by a portable radio inside or near the building, the time delay for the downlink is more critical. The DSP module provides “Down Link, Single Wideband Low Delay Channel” mode to achieve a delay less than 10 microseconds for this case. The screen shot that follows shows a typical module in this mode. Many of the GUI controls are the same as those described above. The following screen shot shows a typical Down Link module in this case Down Link Window 11 (DLW11). Notice that the BW: is set to 3 MHz. The BW control lets the user select from 50kHz, 100 kHz, 150 kHz, 200 kHz, 250 kHz, 500 kHz, 1 MHz, 1.5 MHz, 2 MHz, 2.5 MHz, 3 MHz, 3.5 MHz, 4 MHz, 5 MHz or 5.5 MHz. There are two gain modes available Fixed Gain and AGC. In fixed gain mode there is an edit box labeled “Fixed Gain/Atten (dB):”. In the case shown above the fixed gain is set to -9 dB. For downlink the signals are relatively strong. They arrive from the communication hub via the fiber at a level of -10 dBm. For DLW11 the signal will pass through a 4:1 combiner and then a 5 watt amplifier to the Distributed antenna system. The value of -9 dB has been chosen to make the level at the DAS after the loss in the combiner and the gain of the amplifier the specified level. Some down link module outputs pass through either no combiners or combiners with different losses so the values in the fixed gain box vary to compensate for the signal path. If AGC mode had been chosen then the prompt text would read “Output Setpoint (-dBm):” and the DSP circuitry would adjust the gain to make the output equal to the value in the edit box. The WB Squelch choices are WB Squelch Always OFF, WB Squelch Always ON and WB Squelch Carrier. The latter is the usual choice with the others used mostly for testing. There is red or green text that indicates whether the squelch is off or on. As you can see there is also a measure of the input and output signal level displayed. Notice the slider control labeled RX Attenuator in the upper right corner of the screen. For the downlink mode it is set to 20 dB of attenuation. That is because the input is relatively strong at -10 dBm. For the uplink mode the signals may be quite weak, as low as -83 dBm, when they arrive at the DSP module so for uplink the RX attenuator is set to 0 dB of attenuation. At the bottom of the GUI are two pushbuttons. The “Program Board Settings” pushbutton causes the changes currently on the GUI controls to be saved to the DSP module’s non-volatile memory. The settings are loaded into the Digital Signal Processing hardware when the power to the module is turned on. The pushbutton labeled “Update Firmware” is used to write new firmware into the DSP module. It lets the user select a “.BIT” file to load. This should only be done when AMDI sends a new firmware file and the new file has been loaded onto the PC. The present firmware file is on the PC named AmdiDspWtc.bit.
