1.2 GSM-R BSC6000 Specifications 1.2.1 Product Specifications BSC6000 uses a modular structure. Therefore, smooth evolution from the minimum configuration 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 one subrack (GMPS) is configured. The maximum configuration of the BSC6000 consists of four cabinets, in which one GMPS, three GEPSs, and four GTCSs are configured. The independent fan subrack is added to the BSC6000 cabinet, improving the heat dissipation capability of the cabinet. Table 1-1 Product specifications Performance

Maximum specifications: 4096 TRXs, 24,000 Erlang, 5,900,000 BHCA, 16,384 activated PDCHs, and 1536 Mbit/s bandwidth on the Gb interface

1.2.3 General Principles of Configuring Hardware BSC6000 supports resource pools in the BSC and works preferentially in resource pool mode in GMPS. Based on this, the principles of BSC6000 hardware configurations are as follows: 1. Interface boards and processing boards should be distributed as evenly as possible among subracks. This reduces the consumption of processor resources and switching resources by inter-subrack switching. Interface boards can be configured only in the rear slots, and processing boards can be configured in front or rear slots. Under a BSC, A interface boards, Ater interface boards, Abis interface boards, XPUb main processing boards, DPUc, and DPUd should all be distributed as evenly as possible 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 a pair 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 interface boards. This reduces the impact of transmission faults and board faults on the system. If there are multiple pairs of No.7 signaling links, distribute them evenly among interface 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 boards cannot exceed 2 Mbit/s, and the bandwidth of the signaling links carried on a pair of multi-core interface boards cannot exceed 8 Mbit/s. 4. 5.

The total number of the XPU boards, which contains XPUa and XPUb, should not exceed 14 pairs. General principles of configuring boards are as follows:

Internal

a.

The TNUa boards are always installed in slots 4 and 5 which can also be configured 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 be installed 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 can be installed only in rear slots.

d.

The OMUc boards should be installed in slots 24 and 25. It should be installed 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/TC separate 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 provides access over the air interface and manages the air interface for cab (CAB RADIO, DATA RADIO) and Mobile Stations (MS). The Network Subsystem (NSS) consists of the MSC, HLR, SGSN, GGSN and IWF. It provides functions such as switching, mobility management, and security management for the GSM-R system. Figure 1-3 shows the typical structure of the GSM-R network. Figure 1-1 Typical structure of the GSM-R network
