Compared with issue 04 (2010-11-30) of V900R012C01, this issue does not exclude any topics.
2 Introduction to Initial Configuration
Initial configuration creates the configuration script for the equipment to start to operate.
l The configuration script can be created by running MML commands on the BSC6900 LMT.
For the LMT operation guide, see the BSC6900 GSM LMT User Guide.
l During commissioning, the script is imported to the BSC6900. For data modification after the BSC6900 starts operating, see the GBSS Reconfiguration Guide.
l After the BSC6900 starts operating, operators can enable or disable features based on site requirements. The related data configuration does not belong to initial configuration. For details, see the GBSS Feature Activation Guide.
3 Data Preparation for Initial Configuration
In the BSC6900 initial configuration, some data is obtained from the data sheets after negotiation with other network elements. The negotiated data includes the global data, equipment data, interface data, base station data, and cell data.
For the data preparation for BSC6900 initial configuration, see GSM Data Preparation for the Initial Configuration.
For the restrictions on the parameter settings in MML commands, see BSC6900 GSM MML Command Reference.
4 Initial Configuration Procedures
This chapter describes the process of creating the initial configuration script for the BSC6900.

----End
7.6 Configuring the Clocks
This section describes how to configure the BSC6900 clocks. You need to configure the clock source of interface boards, clock source of the system, and work mode of the system clock source.
Prerequisite
The basic data of the BSC6900 has been configured. For details, see Configuring the Basic Data.
Context
NOTE
The BSC6900 clock information is determined during network planning. In an all-IP over FE/GE network, you do not need to configure a clock source for the BSC6900, and at this time, the BSC use the local oscillator as default.
The clock source of the BSC6900 can be an external clock, line clock, or GPS clock.
l External clock
An external clock can be a BITS clock or an external 8 kHz clock. When the clock source is an external clock, the BSC6900 receives the external clock from CLKIN0 or CLKIN1 on the GCUa/GCGa board.
l Line clock
The line clock is the 8 kHz clock transmitted from an interface board to the GCUa board.
It can be an A interface line clock or an Abis interface line clock. An A interface line clock is extracted by a BSC6900 A interface board from the MSC. An Abis interface line clock
is extracted from a BSC6900 Abis interface board from the transport network, and the base station can synchronize its clock with the BSC6900 clock.
NOTE
l A interface line clock
l When the BSC uses the A interface line clock and FR transmission is used on the Gb interface, if the the Gb interface is configured on the independent board, the clock is selected as follows:
If the SGSN and the MSC use the same clock source, you do not need to configure the Gb interface clock. If the SGSN and the MSC use different clock sources, you need to configure line clocks on both the A and Gb interface boards. In the latter case, set Use SGSN clock source to YES, and set Port for LINE1 and Back-up port for LINE1 to the numbers of the interface board ports carrying BC.
l When the BSC uses the A interface line clock and FR transmission is used on the Gb interface, if the Gb interface and the A/Ater/Abis interface are configured on the same board, you can not set Use SGSN clock source to YES.
l Abis interface line clock
When the BSC6900 uses the Abis interface line clock, the TDM transport network must provide stable clock information. The Abis interface line clock is recommended when the A interface uses IP transmission and the Abis interface uses TDM transmission.If the Gb interface and the A/Ater/Abis interface are configured on the same board, you can not set Use SGSN clock source to YES.
l GPS clock
The GPS clock is the satellite synchronization clock. When the GCGa board is configured with a satellite card, the BSC6900 can use the satellite antenna port on the GCGa board to receive GPS clock signals.
Procedure
l Configuring the external clock
1. Run the ADD CLKSRC command to add a system clock source and the clock source priority.
NOTE
l Clock source type
l If the clock signals are extracted from the CN by the interface board (such as the OIUa/
EIUa/PEUa interface board) in the EPS and then sent to the GCUa/GCGa board in the MPS through the panels, Clock source type of the MPS needs to be set to
BITS1-2MHZ or BITS2-2MHZ.
l If the clock signals are extracted from the CN by the interface board in the MPS and then sent to the GCUa/GCGa board through the backplane of the MPS, Clock source type should be set to LINE1_8KHZ or LINE2_8KHZ.
l If the clock signals are provided by the external BITS, Clock source type should be set to BITS1-2MBPS, BITS2-2MBPS, BITS1-1.5MBPS, or BITS2-1.5MBPS.
l If the clock signals are provided by the GPS and then sent to the GCGa board, Clock source type should be set to GPS.
l If the clock signals are provided by the external 8 kHz clock, Clock source type should be set to 8KHZ.
l Clock source priority
Clock source priority ranges from 1 to 4. The clock source of priority 0 is configured by default. Priority 0 is the lowest priority. The descending ranking of priorities is 1, 2, 3, and 4.
2. Run the SET CLKMODE command to set the work mode of the system clock source.
NOTE
It is recommended that System clock working mode be set to AUTO(Auto Handover) so that the system can switch to the highest-priority clock source when the current clock source is unavailable.
l Configuring the line clock
1. Run the SET CLK command to set the clock source of the interface board.
NOTE
When the system clock is the line clock, interface boards need to be configured with clock sources.
l A interface line clock
In BM/TC combined configuration mode, the A interface board of the MPS needs to be configured with a clock source. In addition, the link number for the clock source needs to be specified, and the backplane 8 kbit/s clock output switch needs to be turned on.
In BM/TC separated configuration mode, the interface boards in both the TCS and MPS need to be configured with clock sources.
l For the TCS, the A interface board of the TCS needs to be configured with a clock source. In addition, the link number for the clock source needs to be specified, and the backplane 8 kbit/s clock output switch needs to be turned on. If multiple TCSs are configured, the A interface board of each TCS needs to be configured with a line clock, and different TCSs need to be configured with different clock sources.
l For the MPS, the Ater interface board of the MPS needs to be configured with a clock source. In addition, the link number for the clock source needs to be specified, and the backplane 8 kbit/s clock output switch needs to be turned on.
l For the MPS, the Ater interface board of the MPS needs to be configured with a clock source. In addition, the link number for the clock source needs to be specified, and the backplane 8 kbit/s clock output switch needs to be turned on.
