Procedure Step 1 Check the information related to the faulty ECM. (1) Enter the MML command DSP CBTSCFG, select CBTSECM for CFGID, and then run this command. Check the configuration information about the ECM and record the ECM configuration. (2) Enter the MML command DSP CBTSCFG, select CBTSCDMADOCHIPPARA for Query Configuration Data, and then run this command. Record the parameter settings of the ECM chip. If the query result is NULL, query the initial value through the MML online help. (3) Run the MML command DSP CBTSBRDSPECSTAT to query the special status of the ECM. Record the chip type and the number of chips. For example, Number of CSM6850 Chips = 2 indicates that the board is a 6850 dual-chip board. Step 2 Check the working mode of board and chip configured on the ECM based on the installed ECM. (1) Check whether the working mode of board and chip configured on the ECM matches the installed ECM. In the case that the board working mode (channel) is 9 or 12, and the working mode of the chip is NORMAL, the type of the ECM should be a 6850 dual-chip board. In the case that the board working mode (channel) is 6, and the working mode of the chip is PIC/Boomer, the type of the ECM should be a 6850 dual-chip board. Note: The ECM is categorized into the 6800 single-chip board, 6850 single-chip board, and 6850 dual-chip board. If the working mode of board and chip configured on the ECM matches the installed ECM, contact Huawei Customer Service Center. If the working mode of board and chip configured on the ECM does not match the installed ECM, make adjustment according to requirements. To change the board working mode of the ECM, go to step 3. To change the chip working mode of the ECM, go to step 4. To replace the ECM, go to step 5. Step 3 Change the board working mode of the ECM. (1) Enter the MML command DSP CBTSCFG, select CBTSSECTORCARRIER for Query Configuration Data, and run this command to query the BTS sector carrier configuration. Record the configuration information of all the carriers on the ECM. Enter the MML command DSP CBTSCFG, select CBTSTRM for Query Configuration Data, and run this command to query the TRM configuration. Record the information about the TRM configured on the optical port of the ECM. (2) Run the MML command RMV CBTSSECTORCARRIER to remove all the carriers on the ECM. If a TRM is configured on the optical port of the ECM, run the MML command RMV CBTSTRM to remove the TRM. 39-2

Airbridge BTS CDMA Base Station Alarm Reference
Procedure Step 1 Query the current link status. (1) Run the MML command DSP CBTSLNKSTAT to query the current status of the E1/T1 link used by the BTS. If any link status is abnormal, go to step Step 1.2. If the status of all the links is normal, go to step 2. (2) Check the E1/T1 cable. Check for damaged cables, loose connectors, or missed or distorted pins on connectors, and then clear the E1/T1 link fault. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, contact Huawei Customer Service Center. Step 2 Query the current link group status. (1) Run the MML command DSP CBTSBRDSPECSTAT to query the status of BTS interface boards (including BCIM/CMPT_TRS/UTRP). Check whether all the sublinks in the link group are in available status. If the status of any sublink is unavailable, go to step Step 2.2. If the status of all the sublinks is available, go to step 3. (2) Clear the transmission fault according to the corresponding handing suggestions for the alarms such as PPP Link Interrupted alarm and IMA link related alarms. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, go to step 3. Step 3 Increase the link bandwidth. (1) Add transmission links over the Abis interface, and increase the available bandwidth for transmission. If the link type is ATM or IP over E1 and some more E1/T1 links can be added for the alarm associated interface board, add more physical E1/T1 link connections for this interface board. Run the MML command ADD CBTSLNK to configure the new added E1/ T1 links as the sublinks of the existing link group. If all the E1/T1 ports of the BTS interface board are in use, add more BTS interface boards to provide more physical E1/T1 connections, and configure these corresponding links and link group at the local and remote ends. To add FE links to increase transmission bandwidth, you need to add corresponding FE ports and routings at the local and remote ends. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, contact Huawei Customer Service Center. ----End 63-2

System Actions The system automatically sets the status of the faulty sublink in the IMA group to unavailable status.
Possible Causes l
The E1/T1- relevant alarm exists.
l
When the link group works properly, the connection to the peer E1/T1 link changes dynamically.
l
The link configuration on the BTS side is inconsistent with that at the peer end of the link.
Procedure Step 1 Check for any alarms about E1/T1 links. (1) Run the MML command DSP CBTSLNKSTAT to query whether the status of the E1/T1 link used on the BTS side is normal. If the status of any link is abnormal, go to step Step 1.2. If the status of all the links is normal, go to step 2. (2) Check whether the E1/T1 transmission link is normal. Check for any damaged cable, loose connector, or bent/broken pin on the connector. If any fault exists, clear the fault. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, go to step 2. Step 2 Use the LMT to check the link type. (1) Enter the MML command DSP CBTSCFG, select CBTSLNKGRP for Query Configuration Data, and then run this command. Obtain the link group type in the query result. If the link group type is Fractional IMA or Fractional, go to step 3. If the link group type is IMA, go to step 4. If the link group type is UNI, go to step 5. Step 3 Check the configuration of the Fractional IMA or Fractional link. (1) Run the MML command DSP CBTSBRDSPECSTAT to query the configuration of the link group on the BTS side. (2) Query the link group configuration at the peer end (may be the BSC or other IMA transmission equipment), and check whether the configurations at both ends are consistent. If the peer end equipment is the BSC, run the MML command LST IMALNK to query the link group configuration on the BSC. The queried number of occupied time slots must be the same and the slot numbers must match. If the configurations match, go to step 6. If the configurations do not match, go to step Step 3.3. (3) Run the MML command RMV CBTSFRACLNK to delete the mismatched sublinks in the link group. When only one sublink is configured in the link group, run the MML command 64-2

Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, go to step 6. Step 4 Check the configuration of the IMA group where the IMA link belongs. (1) Run the MML command DSP CBTSBRDSPECSTAT to query the configuration of the link group where the IMA link belongs on the BTS side. (2) Query the IMA link group configuration at the peer end (may be the BSC or other IMA transmission equipment). If the peer end equipment is the BSC, run the MML command LST IMALNK to query the link group configuration on the BSC. The queried number of sublinks and time slots must be consistent at both ends. If the configurations are consistent, go to step 6. If the configurations are inconsistent, go to step Step 4.3. (3) Run the MML command RMV CBTSLNK to delete the mismatched sublinks in the link group. When only one sublink is configured in the link group, run the MML command RMV CBTSLNKGRP to delete the link group, and then run the MML commands ADD CBTSLNKGRP and ADD CBTSLNK to modify the link group where the IMA link resides and ensure that the IMA group configurations at the two ends match Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, go to step 6. Step 5 Use the LMT to check the configuration of UNI links. (1) Run the MML command DSP CBTSBRDSPECSTAT to query the configuration of the UNI links on the BTS side. (2) Query the UNI link configuration at the peer end (may be the BSC or other IMA transmission equipment). If the peer end equipment is the BSC, run the MML command LST UNILNK to query the link group configuration on the BSC. The queried time slot configurations at the two ends must match. If the configurations match, go to step 6. If the configurations do not match, go to step Step 5.3. (3) Run the MML command RMV CBTSLNKGRP to delete the mismatched link group. Then, run the MML commands ADD CBTSLNKGRP and ADD CBTSLNK to modify the UNI link configuration on the BTS side and ensure that the UNI link configurations at the two ends match Check whether the alarm is cleared.

72 ALM-19397 PPP Link Fault
Procedure Step 1 Use the LMT to query the E1/T1 link status. (1) Enter the MML command DSP CBTSCFG, select CBTSLNK for Query Configuration Data, and then run this command to obtain the information about the sublinks configured in the link group. Then, run the MML command DSP CBTSLNKSTAT to query the status of the corresponding E1/T1 link. If the status of any E1/T1 link is abnormal, go to step Step 1.2. If the status of all the links is normal, go to step 2. (2) Check whether the E1/T1 transmission link is normal. Check for any damaged cable, loose connector, or bent/broken pin on the connector. If any fault exists, clear the fault. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, go to step 2. Step 2 Check the PPP link configurations at both ends of the link. (1) Run the MML command LST BTSLNK to query the PPP/MLPPP link No. used by the corresponding BTS. Then, run the MML command LST PPPLNK/LST MLPPPLNK to check the PPP/MLPPP link configuration on the BSC side. (2) Run the MML command DSP CBTSBRDSPECSTAT to query the configuration of the PPP links on the BTS side. (3) Check whether the link configurations at the two ends are consistent, including whether the configured timeslots are consistent at the two ends, whether the configured number of sublinks in the link group is consistent at the two ends, and whether the BSC assigns IP addresses to the PPP/MLPPP link group on the BTS side. If the configurations are consistent, go to step 4. If the configurations are inconsistent, go to step 3. Step 3 Reconfigure the PPP link. (1) If the PPP link configuration on the BTS side is improper, run the MML command RMV CBTSLNK to delete the link. When only one PPP link is configured in the link group, run the MML command RMV CBTSLNKGRP to delete the PPP/MLPPP link group. If the link configuration on the BSC side is improper, run the MML command RMV PPPLNK/RMV MLPPPLNK to delete the mismatched link in the link group. (2) If the link configuration on the BTS side is improper, run the MML command ADD CBTSLNKGRP to add a PPP/MLPPP link group, and then run the MML command ADD CBTSLNK to add a PPP link. If the configuration on the BSC side is improper, run the MML command ADD PPPLNK/ ADD MLPPPLNK to reconfigure the link group. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, go to step 4. Step 4 Reset the board where the faulty PPP link resides. 72-2

Airbridge BTS CDMA Base Station Alarm Reference
Possible Causes l
The expected total output power exceeds the specifications of the power amplifier.
l
The output power of carrier exceeds the maximum power.
Procedure Step 1 Check whether the expected total output power exceeds the specifications for the power amplifier under the current configuration. (1) Determine the ID of the faulty board according to the alarm information. Calculate the output power of a carrier. Calculate the expected total power. Run the MML command DSP CBTSHPAINFO to query the power supported by the power amplifier. Check whether the expected total output power exceeds the rated power of the power amplifier. If the expected total output power exceeds the rated power of the power amplifier, go to step Step 1.2. If the expected total output power does not exceed the rated power of the power amplifier, go to step 2. (2) Run the following commands to adjust the output power of carriers according to the current output power and network planning to ensure that the expected total output power does not exceed the rated power of the power amplifier. Enter the MML command DSP CBTSCFG, select CBTSSECTORCARRIER for Query Configuration Data, and then run this command. Obtain the sector carrier ID of the RF unit in the query result. Run the MML command LST CDMACH to obtain the system type of the carrier in the query result. The MML commands for adjusting carrier power are as follows: MOD CDMACH: used to change the RF gain. SET CBTSRFPARA: used to change the value of Rated Power Adjust Parameter. SET CBTSSECTCARRPARM: used to change the value of Radio Frequency Gain. Check whether the alarm is cleared. If the alarm is cleared, the corrective procedure ends. If the alarm persists, contact Huawei Customer Service Center. Step 2 Check whether the output power of each carrier exceeds the maximum power under the current configuration. (1) Calculate the output power of a carrier. Run the MML command DSP CBTSLICENSE to check whether the base station has the license for high power configuration. If such license is not obtained, the output power of each carrier is within 20 W. If such license is obtained, the output power of each carrier can reach the rated power of the power amplifier. Check whether the power of each carrier exceeds the maximum power. 110-2
