FCC ID: F8I-DLC0802A User Manual - Part 6 ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: Operation Right-click here to open Host Fwd Att pop-up screen Figure 4-8. HOST RF Display Figure 4-9. Host Fwd Att Pop-Up Screen 2.6 Determine Output Signal Level at STM Antenna Port The RF output signal level should be measured at the STM ANTENNA port to verify that maximum composite signal level is at the required level. Use the following procedure to determine the power level: 1. Verify that RF ON/OFF switch on the LPA in the OFF position. 2. Disconnect the antenna cable from the STM ANTENNA port. 3. Connect a spectrum analyzer or RF power meter to the STM ANTENNA port. (Check the input rating of the test equipment. Insert a 30 dB 100 W attenuator if necessary.) Page 4-12 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: Operation 4. Place the RF ON/OFF switch on the LPA in the ON position. 5. If using a spectrum analyzer, proceed to step 6. If using a power meter, measure the composite signal power from the STM and then proceed to step 8. 6. Measure the RF level of a single carrier, such as the control channel, in dBm. Make sure the resolution bandwidth of the spectrum analyzer is 30 kHz. 7. Calculate the total composite signal power using the following formula: Ptot = Pc + 10Log N – (see Note) Where, Ptot is the total composite power in dBm Pc is the power per carrier in dBm as measured in step 6, and N is the total number of channels. Note: If calculating the composite power for a CDMA system, reduce the initial result by 16.23 dBm 8. Record the result measured in step 5 or calculated in step 7. 9. Place the MUTE/NORM/RESET switch on the LPA in the OFF position. 10. Disconnect the spectrum analyzer or RF power meter from the STM ANTENNA port. 11. Re-connect the antenna cable to the STM ANTENNA port. Note: To comply with Maximum Permissible Exposure (MPE) requirements, the maximum composite output from the antenna cannot exceed 1000 Watts EIRP and the antenna must be permanently installed in a fixed location that provides at least 6 meters (20 feet) of separation from all persons. 2.7 Enter Remote Forward Attenuation The STM internal forward path attenuator setting is used to reduce the power level of the composite output signal level at the STM antenna port. The maximum composite output signal level at the STM antenna port is set using the Host internal forward attenuator (see Section 2.4). However, component variations may result in the output power at the STM antenna port being slightly above or below the required power per channel. If this is the case, the STM forward attenuator may be used in conjunction with the Host forward attenuator to add or remove attenuation to produce the required output signal level. If less power is required, the STM forward attenuator may be used to reduce the power level. The default setting is 0 dB. Use the following procedure to change the STM forward attenuation: 1. Click on the REMOTE LPA tab. The REMOTE LPA display will open within the DEMS main window as shown in Figure 4-10. Page 4-13 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: Operation Right-click here to open the Remote Fwd Att pop-up screen RF output signal level Figure 4-10. REMOTE LPA Display 2. Check the level of the RF output signal (as determined in Section 2.6) against the system design plan specifications. Table 4-1 shows the output signal level required to provide 5 watts per channel for systems with 1 to 2 channels. The maximum output signal level permitted for the system is 40.5 dBm (11 Watts). 3. Determine if more or less attenuation is required to produce the required output signal level. 4. Right-click on the Remote Fwd Att section of the display (see Figure 4-10). The Remote Fwd Att pop-up screen will open as shown in Figure 4-11. 5. Enter the required attenuation value and click OK to close the pop-up screen and to make the changes take effect. Table 4-1. Composite Output Signal Levels NUMBER OF CHANNELS OUTPUT SIGNAL LEVEL REQUIRED TO PROVIDE 5 WATTS PER CHANNEL 37 dBm 40 dBm When there are three or more channels, each channel will always be less than 5 watts since the system has a maximum power output of 11 watts (40.5 dBm). Page 4-14 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: Operation Figure 4-11. Remote Fwd Att Pop-Up Screen 6. Verify that the appropriate RF output signal level appears in the RF Pwr-VSWR Low section (see Figure 4-10). This is primarily a reference value and should not take the place of external test equipment when determining the power level of the composite RF output signal. Depending on the modulation type and number of channels, the DEMS software may report a power level that is higher or lower than the actual RF output signal. Note: To comply with Maximum Permissible Exposure (MPE) requirements, the maximum composite output from the antenna cannot exceed 1000 Watts EIRP and the antenna must be permanently installed in a fixed location that provides at least 6 meters (20 feet) of separation from all persons. 2.8 Enter Host Reverse Attenuation The level of the RF signal that should be input to the BTS will vary depending on the type of BTS, the receive distribution, and the number of channels present. To interface with the BTS, the reverse path signal level must be adjusted to provide the signal level required by the BTS. The HU provides from 0 dB of gain to +30 dB of gain in the reverse path. Use the following procedure to set the reverse path gain: 1. Check the BTS manufacturer’s specifications to determine the composite signal level required at the BTS reverse path input port. 2. Determine the overall gain and loss imposed on the signal by the antenna, antenna cable, and by the cables that connect the HU to the BTS. 3. Determine the amount of gain required to raise the reverse path signal to the level required at the BTS. 4. Click on the HOST RF tab. The HOST RF display will open within the DEMS main window as shown in Figure 4-12. Page 4-15 © 2003, ADC Telecommunications, Inc.

The Digivance system requires minimal regular maintenance to insure continuous and satisfactory operation. Components that require regular replacement, cleaning, or testing include the HU and RU fans and the RU outdoor cabinet air-filters. Maintenance also includes diagnosing and correcting service problems as they occur. When an alarm is reported, it will be necessary to follow a systematic troubleshooting procedure to locate the problem. Once the source of the problem is isolated, the appropriate corrective action can be taken to restore service. The only internal components that can be replaced are the cooling fans which mount in the HU, RU, and LPA. The failure of any other component within a unit will required replacement of that unit. 1.1 Tools and Materials The following tools and materials are required in order to complete the procedures in this section: • • • • • • ESD wrist strap IR filtering safety glasses Patch cords with SC connectors 15 dB in-line SC optical attenuators Optical power meter (1550 and 1310 nm) TORX screwdriver (with T10 bit) Page 5-1 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 5: Maintenance FAULT DETECTION AND ALARM REPORTING The Digivance system on-board embedded software detects various unit and system faults and reports them as either Major or Minor alarms. A Major alarm indicates that the system has failed in a way that directly affects RF transport performance. This usually means that some calls or perhaps all calls cannot be made over the system. A Minor alarm means that system performance is not affected or in some cases, that the performance may no longer be optimal. Four types of faults cause a minor alarm to be reported: overtemperature, fan failure, diversity path failure, and an external minor fault (user defined fault). All other faults are reported as a Major alarm. Reporting of Major and Minor alarms is accomplished through the HU alarm contacts, the unit front panel LED’s, the DEMS software Graphical User Interface (GUI), and the Network Operations Center - Network Element Manager (NOC/NEM) interface. The HU is equipped with a set of both normally open (NO) and normally closed (NC) alarm contacts which are used to report both Major and Minor alarms to an external alarm system. The alarm contacts summarize the inputs so that any Major or Minor alarm will trigger an alarm report to the external alarm system. The HU, STM, and LPA front panel LED indicators are used to report specific alarms which are reflected in the LED colors: Green, Red, Yellow, and Off. A description of the Host Unit, Linear Power Amplifier, and Spectrum Transport Module LED indicators is provided respectively in Table 5-1, Table 5-2, and Table 5-3. The DEMS software GUI provides both a summary and a more detailed list of alarm information that includes unit and module level faults, circuit faults, and measured value faults such as voltages, RF power, and temperature. A summary showing a list of all systems and their current alarm status is presented through the Alarm OverView display. A detailed list of alarm information is presented through the HOST alarm display and the REMOTE alarm display. All the inputs that the system reports as alarms are shown in the HOST and REMOTE alarm displays. The NOC/NEM interface provides the same summary and detailed list of alarm information as the DEMS software GUI but in an ASCII text string format. Sending the command GET ALARM SUMMARY produces a list of all systems and their current alarm status. Sending the command GET ALARM ALL for a specific system will produce a detailed list of alarm information for the specified system. Page 5-2 © 2003, ADC Telecommunications, Inc.

TEST PROCEDURES This section provides procedures for common troubleshooting and maintenance tests. Refer to these procedures as needed when specified in the Fault Isolation and Troubleshooting tables in Section 3. 4.1 Optical Power Test A break in an optical fiber or a fault with the optical connector will interrupt communications between linked components or generate excessive errors. Use the following procedure to isolate a problem with an optical fiber or connector. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transmitter of any unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transmitter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the connector. Page 5-10 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 5: Maintenance 1. Put on the IR filtering safety glasses. 2. Notify the NOC or alarm monitoring system operator that the system is going offline. 3. At the HU and at the STM, place the On/Off switches in the OFF position (press O). Note: Turning off the HU and STM disables the respective lasers which is necessary in order to safely inspect and clean the optical connectors. 4. Disconnect the optical fiber connectors for the fiber to be tested at the HU and the STM. 5. Inspect the optical connectors. Verify that connectors are clean and that no scratches or imperfections are visible on the fiber end. Clean and polish the optical connectors if necessary. 6. Connect the optical power meter to the output (receiver) end of the optical fiber. If an attenuator was included in the fiber link, make sure the attenuator is installed. 7. Connect the input (transmitter) end of the optical fiber to the far end HU or STM. 8. At the far end HU or STM, place the On/Off switch in the ON position (press I). 9. Using the far end HU or STM as an optical light source, measure the optical power at the near end of the optical fiber. The power level of the optical input signal at the HU or STM must fall within the following ranges: STM Forward Path Input Signal (Port 1): –15 to –25 dBm (with attenuator installed) HU Reverse Path Input Signal (Port 2): –15 to –23 dBm (with attenuator installed) If the power level of the received optical signal is within the specified range, the optical fiber and the far end unit are good. If the power level of the received signal is not with the specified range, either the optical fiber is faulty or the far end unit optical transmitter is faulty. Continue with test procedure to isolate the problem 10. At the far end HU or STM, place the On/Off switch in the OFF position (press O). 11. Disconnect the optical power meter from the near end of the optical fiber. 12. Connect the optical power meter to the far end HU (Port 1) or STM (Port 2). 13. At the far end HU or STM, place the On/Off switch in the ON position (press I). 14. Measure the optical output power of the far end HU or STM. The power level of the optical output signal from the HU or STM must meet the following specification: HU Forward Path Output Signal (Port 1): 0 + 1 dBm STM Reverse Path Output Signal (Ports 2 and 3): +2 + 1 dBm If the power level of the optical output signal is within specifications, the optical fiber is faulty. If the power level of the optical signal is not within specifications, the far end HU or STM optical transmitter is faulty. 15. At the far end HU or STM, place the On/Off switch in the OFF position (press O). 16. Disconnect the optical power meter from the far end HU or STM. 17. Reconnect the optical fibers at the HU and the STM. Page 5-11 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 5: Maintenance 18. Repeat steps 3 through 17 for each optical fiber that requires testing. 19. When ready to put the system back into service, place the On/Off switch in the ON position (press I) at both the HU and STM. 20. Notify the NOC or alarm monitoring service that the system is going back online. 4.2 Optical Loopback Test The following procedures provide tests to determine if an optical port fault exists with the Host Unit or with the STM. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transmitter of any unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transmitter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the connector. 4.2.1 Host Loopback Test 1. Put on the IR filtering safety glasses. 2. Notify the NOC or alarm monitoring system operator that the system is going offline. 3. At the HU, place the On/Off switch in the OFF position (press O). 4.
