USER MANUAL FOR TC-2000 TC-2000 QI Copyright - refer to title page Page 8ENU Status : 1-1-1 2 EQUIPMENT DESCRIPTION 2.1 BLOCK DIAGRAM Figure 2: System Block Diagram As it is show in figure2,the multi-channal carrier signal from BTS TX1/TX2 port goes into the system at the Input Duplexer. The duplexer filters out the out of band signals and combines the TX carriers in the Input Tray. The combiner signal is the sent through an adjustable attenuator that feeds into the MCPA for power amplification. The signal is then sent through the Output Duplexer and into the antenna at ANT1. In the event of a major fault in the PA or power failure, the bypass switch will be activated to ensure BTS continuous signal coverage. The UL signal from antenna1 goes by ANT1 port into the Output Duplexer where the out-of-band signals get filtered out. The filtered signal then gets sent to the Input Tray where the user has the option of sending the signal through a LNA and adjustable attenuator or bypassing LNA altogether. The signal then gets sent out through the Input Duplexer to the base station.

USER MANUAL FOR TC-2000 TC-2000 QI Copyright - refer to title page Page 35ENU Status : 1-1-1 Commissioning Tasks Observation 1. Install OMT z Activate the OMT Main window. The system Initialization will completed in about 2 minutes. z Click “Connect” button to enquire the amplifier’s status. Proceed if there is no alarm; else check the failure and attend to the alarm. 2. Adjust DL ATT z Observe DL input power from measured value and adjust according accordingly via the ATT1/2 on the front panel. z Note: To ensure that the measured DL input power is accurate, one should set the DL ATT to “0” before performing the check. 3. Configure [Equipment ID] z Go to [Properties Info] and set [Equipment ID]. 4. Comm. Config z Enable the power supply by selecting “On” in [RF] -> [Switch]; go to [Properties Info.] -> [Comm. Config.] and set OMC Phones No. , the service No. of SMSC, Report Mode. 5. Select Monitoring Parameters z Select the equipment controlled and monitored parameters. z If the external devices are connected to the equipment for management, please enable in the [External Alarm Info.] Interface. 6. Test coverage area field intensity and adjust service antenna. z Use test-handset to verify field intensity within the coverage area. If needed, realign the service antenna to achieve the desired coverage. z Note: If during operation, the equipment gain could not be set to maximum or the output power is not high enough due to insufficient donor and service antennas isolation, then the antennas’ position should be changed to increase isolation. If the output power is too high and ALC is activated, then adjust the DL ATT to achieve optimal DL Gain. 7. Verify UL gain and ensure test call produces good voice quality and there is no interfering BTS z Adjust UL gain on TMA if required and perform test calls. Typically, the UL gain is set around 5dB less than DL gain. Perform test calls in the coverage area while adjusting UL gain on TMA if required. z Verify again that there is no unacceptable interference to BTS.
