is extracted from a BSC6900 Abis interface board from the transport network, and the basestation can synchronize its clock with the BSC6900 clock.

NOTE

l A interface line clockl 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 Gbinterface clock. If the SGSN and the MSC use different clock sources, you need to configureline clocks on both the A and Gb interface boards. In the latter case, set Use SGSN clocksource to YES, and set Port for LINE1 and Back-up port for LINE1 to the numbers ofthe 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 cannot set Use SGSN clock source to YES.

l Abis interface line clockWhen the BSC6900 uses the Abis interface line clock, the TDM transport network must providestable clock information. The Abis interface line clock is recommended when the A interfaceuses IP transmission and the Abis interface uses TDM transmission.If the Gb interface and theA/Ater/Abis interface are configured on the same board, you can not set Use SGSN clocksource to YES.

l GPS clockThe GPS clock is the satellite synchronization clock. When the GCGa board is configuredwith a satellite card, the BSC6900 can use the satellite antenna port on the GCGa board toreceive GPS clock signals.

Procedurel Configuring the external clock

1. Run the ADD CLKSRC command to add a system clock source and the clock sourcepriority.

NOTE

l Clock source typel 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 theMPS through the panels, Clock source type of the MPS needs to be set toBITS1-2MHZ or BITS2-2MHZ.

l If the clock signals are extracted from the CN by the interface board in the MPS andthen sent to the GCUa/GCGa board through the backplane of the MPS, Clock sourcetype should be set to LINE1_8KHZ or LINE2_8KHZ.

l If the clock signals are provided by the external BITS, Clock source type should beset 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, Clocksource type should be set to GPS.

l If the clock signals are provided by the external 8 kHz clock, Clock source type shouldbe set to 8KHZ.

l Clock source priorityClock source priority ranges from 1 to 4. The clock source of priority 0 is configured bydefault. Priority 0 is the lowest priority. The descending ranking of priorities is 1, 2, 3, and4.

2. Run the SET CLKMODE command to set the work mode of the system clock source.

Link Control (HDLC), and Internet Protocol (IP) transmission schemes.l Idle ports are available on interface boards.

Contextl Separate mode indicates that boards and carriers that are configured for a BTS must be

configured separately.l Normalization mode indicates that the method for numbering slots, subracks, and cabinets

is normalized, the method for naming boards is normalized, the method for numberingtransmission ports is normalized, and the method for numbering ports reporting customizedalarms is normalized when multiple modes are supported at a base station.

ProcedureStep 1 Run the ADD BTS command to add a BTS.

Table 9-1 Settings of key parametersParameter SettingBTS Name A BTS name must not contain any of the

following symbols:, (comma), ; (semicolon), " (double quotationmarks), ' (single quotation marks), =, %, \,+, &, #

Separate Mode For 3900 series base stations, this parametermust be set to SUPPORT(Support).For BTS3012, BTS3012II, and BTS3012AE,this parameter is set to either SUPPORT(Support) or UNSUPPORT(Not Support).For 3x series base stations, this parametermust be set to UNSUPPORT(NotSupport).

9.1.4 Configuring RF UnitsThis section describes how to configure data for TRX boards, and antenna boards.

Prerequisitel The BTS boards are configured. For details, see 9.1.3 Configuring BTS Boards.

Contextl 3X series and double-transceiver series base stations

The DTRU board enables two logical TRXs to be bound to one physical TRX board. The QTRU board enables six logical TRXs to be bound to one physical TRX board.

l 3900 series base stations The DRRU/DRFU board enables two logical TRXs to be bound to one physical TRX

board. The MRRU/GRFU/MRFU/GRRU board enables eight logical TRXs to be bound to one

physical TRX board.

ProcedureStep 1 Add TRX boards to the base station.

3X series and double-transceiver series base stations1. Run the ADD BTSTRXBRD command to add TRX boards to a base station of the 3X

series or double-transceiver series.l In the case of the BTS3012, BTS3012II, and BTS3012AE, the DTRU or QTRU board

can be configured if Separate Mode is set to SUPPORT(Support).3900 series base stations1. Run the ADD BTSRXUCHAIN command to add an RXU chain or ring.

NOTEThere is no need to add RXU boards or a RXU chain/ring for the BTS3900B.

2. Run the ADD BTSRXUBRD command to add RXU boards.l For the SingleRAN base stations, Cabinet No., Subrack No., and Subrack No. must

be configured.l For the 3900 series base stations RF boards, see 10.3.5 Configuration Rules of the

BTS Boards.l If Is Configure Check threshold is set to NO(NO), need set the bandwidth manually.
