2.1.3 Version Relation Description The hardware model of the PMU supporting this function is PMU01B and the corresponding software version is C01B026SP21 or later later.. For version relation description of other products, see Table 1.1. 1.1.
2.2 Maintainability and Testability of the RF Module and the FPGA Module 2.2.1 Function Description The maintainability and the testability of the RF module and the FPGA module enable the location of the hardware fault of the RF channel. The related functions are as follows:
Using customized messages to initiate cross-reception of UL data on RF channel A or B of the DRFU or to initiate cross-transmission of DL data on RF channels A and B of the DRFU.
The board log records the data collected from the FPGA module.
The DRFU/DRRU log records the key information about the FPGA module periodically. periodically.
2.2.2 Operation Procedure Configuring Before Operation Step 1 On the BSC6900 LMT, run the SET BTSRXUBP command. Set the parameters as follows:
RXU Type: based on actual situation
TX/RX Mode: DOUBLE_ANTENNA
Step 2 On the BSC6900 LMT, run the SET GTRXDEV command. Set the parameters as follows:

2.29 Enhanced DSP Voice Link Detection Capability 2.29.1 Function Description The original voice detection mechanism is enhanced to accelerate the troubleshooting process of online voice services. During a certain period of time, if the number of voice errors in the window (length: 64) exceeds the consecutive error threshold or total error threshold, the related record is written into the log. This function is supported by the GRRU V2 and GRFU.
2.29.2 Operation Procedure Enabling DSP Voice Link Detection Capability Enhancement Step 1 On the MML client of the BSC6900 LMT, run the SET GCELLBTSSOFT command and set the related parameters based on the settings in the network.
Set Item Index to 56
Set Item Value based on the actual situation The Item Value parameter indicates a decimal value that is equivalent to an octet. The meaning of each bit in the octet octet is as follow follows: s: BIT7: function switch. 1 – Disabled; 0 – Enabled BIT6: reserved BIT5 – BIT3: total error threshold ranging from 0 to 7 BIT2 – BIT0: consecutive error threshold ranging from 0 to 7 For example, to set the total error threshold to 7 and the consecutive error threshold to 3, you need to set the Item Value parameter to the decimal 59, which is equivalent to 00111011b, as shown in Figure 1.1. 1.1.

The ten-byte data (in the rectangle above) in the log indicates in sequence the carrier No., channel No., and the number of errors of eight types. An error type occupies a byte. At present, only four of eight error types are used, which are downlink TRAU frame not received, voice frame or SID frame stolen, air-interface CMR time CMI leap, and uplink Dbit all-0 or all-1 frame. The other four error types are reserved.

2.30 Optimized Voice Problem Location 2.30.1 Function Description Many service problems are related to voice, such as the one-way audio, no audio, crosstalk, noise, low MOS for the voice quality, PDCH out-of-synchronization, and low PS service rate. Methods dedicated to locating such problems on the BTS side are not yet developed. Usually, engineers have to capture data on the site with tools such as the MTB, which is inefficient and costly.. On the BSC side, a few location methods are already available for locating voice costly problems. These methods usually involve the the following steps: performing performing dialing test on the BTS affected by the voice problem, saving the TRAU frames that results in the voice problem, and analyzing analyzing the TRAU frames frames with voice analysis analysis tools to locate the cause cause of the problem. These methods can only locate locate internal processing processing problems on the TC TC side. When problems occur to the the interface or air interface between between the BTS and the BSC, the the methods are no longer useful. Therefore, it is necessary to develop the functions of saving, reporting, and analyzing TRAU frames on the BTS side. The PTU record function can be used for saving, reporting, and analyzing the TRAU frames of voice and PS services. During IP- or HDLC-based transmission between the BSC and the BTS, you can use the user plane (UP) 60

Different STMA models provided by different vendors support different gain ranges. Therefore, you should configure the parameter according to the specifications provided by the vendor. The value of the SubUnit No. parameter ranges from 1 to 2. The valid value of the Connection Port No. parameter ranges from 0 to 5 for the GATM and from 0 to 2 for the RXU. The TMA can work in two modes, namely, normal and bypass. The value of the Gain(0.25dBi) parameter ranges from 0 to 255. 255.

2.32 PS Downlink High-Prec High-Precision ision Power Control 2.32.1 Function Description This feature enables the system to perform the PS downlink power control in small granularity.. In this way, power adjustment in granularity of 2 dB and frequent change of granularity coding schemes can be avoided.
2.32.2 Operation Procedure To enable the PS downlink closed-loop power control, perform the following operation: On the BSC6900 LMT, run the SET GCELLPSPWPARA command, and then set the following parameters based on the existing network conditions:
Set Support PS Downlink Power Control to YES(Yes).
Set P0 based on the situation.
Set Power Control Precision based on the situation.
This function and the power ramping in 8PSK mode are mutually exclusive.
