BSC Global Data (BM/TC Separated, External PCU)

This provides examples of BSC global data when the BM and TC are configured in different subracks and the external PCU is used.

BSC global data is determined during network planning. It provides a basis for the configuration of all the other data. After the BSC global data takes effect, do not modify it unless the network is planned again.

BSC global data includes BSC attributes, SS7 signaling points, and the mapping between the GMPS and the signaling point.

BSC Attributes

Parameter	Parameter to Be Configured	Example	Source
Basic Data	BSC Name	BSC001	Network planning
	Country Code	86	Network planning
	City Code	021	Network planning
	MCC	460	Network planning
	MNC	10	Network planning
	A Interface Tag	GSM_PHASE_2+	Network planning
	Um Interface Tag	GSM_PHASE_2+	Network planning
	Abis Interface Tag	GSM_PHASE_2+	Network planning

SS7 Signaling Point

**Table 2** Example of the data negotiated and planned for configuring the SS7 OPC and DPC
Parameter	Parameter to Be Configured	Example	Source
OPC	OPC Name	BSC001	BSC internal planning
	OPC (Hex)	B1	Network planning

DPC	DPC Name	MSC001	BSC internal planning
DPC	DPC(Hex)	D1	Network planning

If there is no direct physical link between the original signaling point and the destination signaling point, you need to configure STPs. In this case, you have to set Using STP to Yes. For the examples of the data negotiated and planned for configuring the STP, see Table 3.
