1.2 GSM-R BSC6000 Specifications
1.2.1 Product Specifications
BSC6000 uses a modular structure. Therefore, smooth evolution from the minimumconfiguration to the maximum configuration can be achieved by adding subracks(GEPS/GTCS) or boards.
The minimum configuration of the BSC6000 consists of one cabinet, in which onesubrack (GMPS) is configured. The maximum configuration of the BSC6000 consists offour cabinets, in which one GMPS, three GEPSs, and four GTCSs are configured.
The independent fan subrack is added to the BSC6000 cabinet, improving the heatdissipation capability of the cabinet.

1.2.3 General Principles of Configuring Hardware
BSC6000 supports resource pools in the BSC and works preferentially in resource poolmode in GMPS. Based on this, the principles of BSC6000 hardware configurations are asfollows:
1. Interface boards and processing boards should be distributed as evenly aspossible among subracks. This reduces the consumption of processor resources
and switching resources by inter-subrack switching. Interface boards can beconfigured only in the rear slots, and processing boards can be configured in frontor rear slots.
Under a BSC, A interface boards, Ater interface boards, Abis interface boards, XPUbmain processing boards, DPUc, and DPUd should all be distributed as evenly aspossible among subracks. Configuring the same type of board in the same subrack
lowers system reliability.
2. Two adjacent slots, such as slots 0 and 1, slots 2 and 3, can be configured as apair of active/standby slots. Two slots, such as slots 1 and 2, or slots 3 and 4,cannot be configured as a pair of active/standby slots.
3. No.7 signaling links should be configured on different A and Ater interfaceboards. This reduces the impact of transmission faults and board faults on thesystem.
If there are multiple pairs of No.7 signaling links, distribute them evenly amonginterface boards based on the quantities of A and Ater interface boards. In principle,the bandwidth of the signaling links carried on a pair of single-core interface boardscannot exceed 2 Mbit/s, and the bandwidth of the signaling links carried on a pair ofmulti-core interface boards cannot exceed 8 Mbit/s.
4. The total number of the XPU boards, which contains XPUa and XPUb, shouldnot exceed 14 pairs.
5. General principles of configuring boards are as follows:

a. The TNUa boards are always installed in slots 4 and 5 which can also beconfigured with DPU boards. The SCUa/SCUb boards are always installed in
slots 6 and 7. The GCUa/GCGa boards are always installed in slots 12 and 13.
b. The DPUf/DPUg boards are service processing boards. They can beinstalled in front or rear slots. It is recommended that they be installed in front
slots.
c. The EIUa/PEUa/POUc/FG2/GOUc boards are interface boards. They canbe installed only in rear slots.
d. The OMUc boards should be installed in slots 24 and 25. It should beinstalled in slot 24 when only one OMUc is configured.
1.3 Network Structure of GSM-R BSC6000
The network structure of GSM-R BSC6000 has the following characteristics: BM/TCseparate mode and BM/TC combined mode.
1.3.1 Traditional TDM Network Structure
The Base Station Subsystem (BSS) consists of the BTS, BSC, and PCU. It providesaccess over the air interface and manages the air interface for cab (CAB RADIO, DATARADIO) and Mobile Stations (MS). The Network Subsystem (NSS) consists of theMSC, HLR, SGSN, GGSN and IWF. It provides functions such as switching, mobilitymanagement, and security management for the GSM-R system.

WP1D000DPU05 DPUf Number =ROUNDUP(MaxIWFPerBSCTDMIP/IWFNoPerDPUfTDMIP, 0) + 1
Note: When IP transmission is used on the Abis interface,this board should be configured. The configurationquantity depends on the number of IWF channels
(TDM&IP) required by the BSC.WP1D000DPU05 worksin N+1 backup mode.
WP1D000DPU06 DPUg Number =ROUNDUP(MaxPDCHPerBSC/PDCHNoPerDPUg, 0) +1
This module should be configured when the built-in PCUis used. The configuration quantity depends on themaximum number of PDCHs required by the BSC.WP1D000DPU06 works in N+1 backup mode.
