For the detailed information of BTS alarms, see the online help and the Airbridge BTS3606E&3606AE CDMA Base Station Site Maintenance Guide or the detailed alarm description of the alarm management system. For the troubleshooting related to BTS startup, see the Airbridge BTS3606E&3606AE CDMA Base Station Site Maintenance Guide. 3.2.2 Description of the BTS Startup Process This section details the steps shown in Figure 3-2. Board Initialization After the BTS is powered on, the BOOT software of each board transfers the board software from the Flash memory to the RAM. After the board self-test and initialization, the communication link between the boards is set up. If the board initialization fails, the board resets. Table 3-1 describes the symptom of board initialization. Table 3-1 Symptom of board initialization Observation Method Description Through indicators of the BTS During the power-on and initialization process of the BCKM and the BCIM, the RUN indicator flashes fast at 4 Hz. Before the operation and maintenance link (OML) is set up, the ACT indicator on the BCKM flashes fast at 4 Hz. The frequency at which the ALM indicator flashes varies with the alarm level. On the service maintenance system The BTS is in the link interruption state. Setting Up the OML After the self-test, the baseband boards set up the OML with the BSC. Setting up the OML from the BTS to the BSC is the prerequisite for configuring the BTS at the far end. The physical bearer between the BTS and the BSC can be E1/T1 or FE. These bears can be used to transmit ATM cells and IP packets. The BTS supports the following three modes for setting up OMLs: 3-4 Setting up the OML in ATM over E1/T1 mode Setting up the OML in IP over E1/T1 mode Setting up the OML in IP over FE mode Huawei Technologies Proprietary Issue 02 (2006-10-10) Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process If the OML cannot be set up during the BTS startup, the BTS restarts five minutes later. If the OML is interrupted when the BTS is processing services, the BTS sets up the OML repeatedly but the BTS do not restart. Before querying the status of the CTRM/OMTR, ensure that the status of the CCPM/CECM is normal. The following details three modes for setting up OMLs. The process of setting up the OML in ATM over E1/T1 mode is as follows: Step 1 When the BTS is started, the BCKM sends a BOOTP request to the CMUX of the BSC. Step 2 The CMUX writes into the BOOTP frame the information of the transmission channel and transfers the information to the BAM. This information is used as the address parameters of the client BTS and is called BOOTP information. Step 3 After receiving the BOOTP request, the BAM obtains the BTS ID according to the BOOTP information (execute the command ADD BTSBTPINFO to map the BTS ID to the BOOTP information). Step 4 The BAM obtains the maintenance IP address of the BTS according to the BTS ID (execute the command ADD BTS to map the BTS ID to the maintenance IP address). Step 5 The BAM writes the maintenance IP address into the BOOTP response frame and sends the frame to the BTS. Step 6 After obtaining the maintenance IP address, the BTS sends a request for setting up a TCP link to the BAM. Step 7 The BAM receives this request and sets up the OML from the BTS to the BAM. ----End In the case of setting up the OML through the E1/T1 link in the IP transmission mode, after two BOOTP requests, the BTS obtains the IP address of the BCIM, routing information, and maintenance IP address of the BTS. For the details of the BOOT requests of the BCKM, see the description of setting up the OML in ATM over E1/T1 mode in 3.2.2 "Description of the BTS Startup Process." The process of setting up the OML in IP over E1/T1 mode is as follows: Step 1 When the BTS is started, the BCIM sends the PPP setup request to the BSC. After obtaining the PPP IP address, the BTS sets up a PPP connection with the BSC. Step 2 The BCIM sends a BOOTP request to the CBPE of the BSC. Step 3 After receiving the BOOTP request, the CBPE obtains the IP address and routing information of the BCIM from the BOOTP transmission channel. Step 4 The CBPE writes the maintenance IP address of the BCIM into the BOOTP response frame and sends it to the BCIM. Step 5 The BCKM sends the BOOTP request to the BSC and obtains the maintenance IP address of the BTS. Step 6 After obtaining the maintenance IP address, the BTS sends a request for setting up a TCP link to the BAM. Issue 02 (2006-10-10) Huawei Technologies Proprietary 3-5 Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process Step 7 The BAM receives this request and sets up the OML from the BTS to the BAM. ----End In the case of setting up the OML in IP over FE mode, the IP address of the BCIM and the O&M IP address of the BTS cannot be obtained through the BOOTP if the BTS starts for the first time. You must configure them at the BTS side. The process of setting up the OML in IP over FE mode is as follows: Step 1 Execute the command SET CBTSBCIMIP to set the IP address of the BCIM. Step 2 Execute the command ADD CBTSFEPORT to set the FE port on the BCIM. Step 3 Execute the command ADD CBTSIPROUTE to set the BTS routing information. Step 4 Execute the command SET CBTSOAMIP to set an IP address of the BTS O&M. Step 5 The BTS sends a request for setting up an OML with the BSC. Step 6 The BAM receives the request and sets up an OML from the BTS to the BSC. ----End Table 3-2 lists the indicator status during the OML setup. Table 3-2 Indicator status during the OML setup Observation Method Description Through the indicators of the BTS After the OML is set up normally, the ACT indicators of the BCKM and BCIM are ON. On service maintenance system After the OML is set up normally, you can view the running status of the BCKM and the BCIM on the equipment panel. Searching Satellites After being initialized, the BCKM searches the satellite to obtain stable and reliable clock signals for the BTS. If satellite searching fails, the ACT indicator of the BCKM flashes slowly. At the same time, the CCPM or the CECM restarts repeatedly. If the standby BCKM is configured and it can search satellite normally, the standby BCKM switches over to the active one. Downloading and Activating Data Configuration Files The BTS downloads and activates the data configuration files from the BAM first. If the software version of the board is not consistent with that of the BAM and the switch of auto-download is on, the BTS downloads the board software automatically. If the OML setup fails and the data configuration files are saved in the Flash memory of the BCKM, the BTS directly activates the data configuration files in the Flash memory. 3-6 Huawei Technologies Proprietary Issue 02 (2006-10-10) Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process Table 3-3 lists the indicator status when the BTS downloads data configuration files. Table 3-3 Indicator status when the BTS downloads data configuration files Observation Method Description Through the indicators of the BTS The board resets. After the boards run normally, the ACT indicator switches on. At the service maintenance system After the configuration, you can view the running status of all the boards on the equipment panel. Observing the correlated alarm The alarm related to link interruption is generated. Setting Up Traffic Links After the BTS obtains a stable clock signal, the CCPM or the CECM sets up the Abis traffic link through the BCIM according to the configuration parameter obtained from the operation & maintenance unit (OMU). Then the CCPM or the CECM exchanges traffic data with the BSC. Setting Up Signaling Links After the configuration, the BCKM sets up the Abis signaling link to communicate with the BSC through the BCIM according to the configuration parameter obtained from the OMU. When the Abis signaling link is interrupted, the BTS resets automatically 10 minutes later. Setting Up Cells After the Abis signaling link is set up, the BCKM reports the BTS resource configuration state to the BSC and requests logical configuration. After the BSC sends the cell configuration data to the BCKM, the BTS configures the carrier properties, sets up the common channel, and updates the overhead message. After that, the MS is allowed to access the network and make a call. 3.3 Starting Local Maintenance This section describes the process of starting local maintenance. 3.3.1 Configuring the WS Task Description Configure the IP address of the WS which is used for commissioning.

During this period, the index of transmit signals cannot satisfy the rated requirement and the adjacent channels are affected. 3.5.1 Forward Power Test This section describes how to conduct a forward power test. It also describes the precautions you must take before conducting a forward power test. Precautions Pay attention to the following points when conducting a forward power test: The fan box must be installed to ensure the normal operation of the power amplifier. Power unit is 0.1 dBm. Ensure that the coupling port without the connection lines is connected to a matching load to avoid generating internal interference and external radiation. Consider RF cable loss (it is related to the texture and thickness of the RF cable) when analyzing the test result. In general, the loss of one-meter cable is 0.5 dB, and that of two-meter cable is 1 dB. Before the power test, stop all services. The TRM restarts after the test is complete. Connect the power meter to the TX/RX-TEST port using an RF coaxial cable and then perform the power test. Take the cable loss and the coupling degree of the TX/RXM-TEST port into account. The coupling degree of the TX/RX-TEST port is available in the model information of this port. It is generally 30 dB. If a high-precision power meter is used, carry out the test on the antenna port and test port. If a low-precision power meter is used, carry out the test on the antenna port. Test Procedure The test procedure is as follows: Step 1 Connect the cables. Figure 3-8 shows the connection for forward power test when configuring a CDDU. Issue 02 (2006-10-10) Huawei Technologies Proprietary 3-21 Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process Figure 3-8 Connection for forward power test TX2/RX2 - ANT TX2/RX2 - TEST CDDU TX1/RX1 - ANT TX1/RX1 - TEST BTS cabinet top Power meter Antenna Step 2 In the Windows operating system of the LMT, select Start > Run, type Telnet xxx.xxx.xxx.xxx in the Run dialog box, and then press Enter to start Telnet. For the near end Telnet, the default IP address of the Ethernet port is 172.16.16.16. Step 3 Start the power test for the BTS transmitting at full power. For example, for the 450A carrier, execute the following commands: HW CBTS>str trmpowertst:brdid=2,chid=0,channo=210 Are you sure?(Y or N)y Ok HW CBTS>str trmpowertst:brdid=2,chid=1,channo=160 Are you sure?(Y or N)y Ok HW CBTS>str trmpowertst:brdid=2,chid=2,channo=260 Are you sure?(Y or N)y Ok "chid" is the ID of a carrier provided by the TRM. The IDs of the carriers provided by the CMTR/OMTR are 0, 1, and 2. "channo" is the center frequency of the carrier. You must test the powers of the three carriers of the CMTR/OMTR at the same time. Step 4 After preheating the BTS for ten minutes, check the output power that is displayed on the power meter and record the value. Step 5 Analyze the test result. See section 3.5.2 "Forward Power Test Analysis." If the result is abnormal, handle the situation according to section 3.5.2 "Forward Power Test Analysis." 3-22 Huawei Technologies Proprietary Issue 02 (2006-10-10) Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process Step 6 If the result is normal, conduct forward power interface tracing and compare the test result with the power test result. For example, to trace the CMTR or OMTR configured in slot 2, execute the following commands: HW CBTS>str infotrace <(brdtp=?bckm_omu/bckm_sig/bckm_clk/bcim/ccpm/trm), mandatory >trm <(brdid=?),mandatory >2 <(item=?),optional>"power" ok Step 7 Stop forward power interface tracing. For example, to stop tracing the CMTR or OMTR configured in slot 2, execute the following commands: HW CBTS>stp infotrace <(brdtp=?bckm_omu/bckm_sig/bckm_clk/bcim/ccpm/trm), mandatory >trm <(brdid=?),mandatory >2 <(item=?),optional>"power" ok Step 8 Repeat steps 1 to 5 to test other CMTRs or OMTRs. Step 9 Stop the power test as follows: HW CBTS>stp trmpowertst <(brdid=?),mandatory >2 <(chid=?),mandatory >1 ok ----End 3.5.2 Forward Power Test Analysis This section provides the parameters and analysis of forward power test results. Troubleshooting methods are also provided for abnormal test results. Parameter Description Table 3-4 describes the parameters associated with the forward power test.

TRM2: Base band power: carrier0 = ***, carrier1 = ***, carrier2 = *** Digital power : carrier0 = ***, carrier1 = ***, carrier2 = *** Attenuation : carrier0 = ***, carrier1 = ***, carrier2 = *** Digital power sum = ***., HPA Output power = ***, HPA Input power = *** Obs chan power = ***, Obs gain adjust = ***, Obs gain Identical = *** IF gain adjust = ***, RF gain adjust = ***, DDU gain adjust = *** PD RMS Error = ***, DAC Input Power = ***, RF Forward Power = *** Analysis of Test Result The analysis of the test result is described as follows: The normal output power (Digital power) for a carrier is 43 dBm ! 1 dB (that is, 20 W ! 1 dB). If the test result displayed on the power meter is out of normal range, compare it with the result of interface tracing. Troubleshooting Some common troubleshooting methods are as follows: 3-24 If the test result displayed on the power meter is out of normal range, start interface tracing to check the values of the parameters Base band power, Digital power, and HPA Output power. In theory, if the value of the parameter Base band power is not normal, the values of Digital power and HPA Output power are also not normal. In such a case, check if the BTS gain is set correctly. If BTS gain is correct, analyze the CCPM performance and CECM performance by querying BTS configuration and checking the CSM5000/CSM5500/CSM6800. Huawei Technologies Proprietary Issue 02 (2006-10-10) Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process If Base band power is normal, but Digital power is not normal, the values of HPA Output power must be not normal in theory. In such a case, check the CMTR or OMTR to locate the fault. For example, insert and remove it, or replace it. If only HPA Output power is not normal, check the installation of CMPA or OMPA and its connection with the CMTR or OMTR. If all the parameter values reported in the interface tracing are normal, do as follows: − Check the connections between the CMPA/OMPA and the CDDU/IDFU/ODFU. − Check the antenna system and ports on the top of the cabinet for errors. 3.5.3 Reverse RSSI Test The RSSI test includes the local RSSI test and the remote RSSI test. In the case of the remote RSSI test, you can perform the reverse RSSI test by: Selecting Resource Monitoring > RSSI Monitoring, or Logging in to the BTS in Telnet mode. In the case of local RSSI test, you can connect the WS to the BCKM by using a crossover Ethernet cable and then log in to the BTS in Telnet mode. In this mode, you can use commands to perform BTS commissioning. This section describes how to conduct reverse RSSI tests in the local RSSI test. It also describes the precautions you must take when conducting the tests. Precautions Note the following points before conducting the forward power test: You can choose not to install RF fans; however, to ensure zero transmission power, you have to connect the antenna with the CDDU/CDFU. The unit for the average and peak values of RSSI is 0.1 dBm. Check whether the coupling port without connection lines is connected to a matching load to avoid generating internal interference and external radiation. Test Procedure The test procedure is as follows: Step 1 Connect the cables as shown in Figure 3-9. Figure 3-9 Connection for reverse RSSI test of the BTS Network port BCKM Crossover cable BTS Issue 02 (2006-10-10) Huawei Technologies Proprietary 3-25 Airbridge BTS3606E&3606AE System Commissioning Guide 3 Commissioning Process Step 2 In the Windows operating system of the LMT, select Start > Run. Step 3 In the Run dialog box, type in Telnet xxx.xxx.xxx.xxx, and then press Enter to run the Telnet program. Step 4 Check the BTS configuration, and ensure that the data configuration complies with the actual cable connection of the RF subrack. Step 5 Start reverse RSSI test. For example, to trace the CMTR or OMTR configured in slot 1, execute the following commands: HW CBTS>str infotrace <(brdtp=?bckm_omu/bckm_sig/bckm_clk/bcim/ccpm/trm), mandatory >trm <(brdid=?),mandatory >1 <(item=?),optional>"rssi" Ok Step 6 Record test results.
