3. Hardware Configuration of NE3

n Select boards

NE3 uses the OptiX OSN 9500 to work as the STM-64 MADM.

Table 3-9 Board configuration of NE3

Board type	Board	Number (piece)	Configuration description
Service board	JL64	4	NE3 configures two JL64 boards because it needs two STM-64 optical interfaces to form an STM-64 ring. According to the feature of the OptiX OSN 9500, the JL64 connects to NE2 uses S-64.2b optical module, the JL64 connects to NE4 uses V-64.2b optical module. NE3 configures two more JL64 boards because it needs two STM-64 optical interfaces to form an STM-64 ring with NE2 and NE20.
	JLQ4	2	There are 8 x STM-4 services between NE3 and NE2, here use two JLQ4 boards to add/drop the STM-4 service at NE3.
	JLHE	1	NE3 needs to add/drop 16 electrical interface STM-1 services.
	GE06	1	NE3 needs to add/drop 1000 Mbit/s Ethernet service.
Required board	GXCH	4	The service capacity of this node is 400 G, and the cross-connect board needs backup protection.
	JSTG	2	Prepare two JSTG boards, one of which serves as backup.
	JPIU	2	Prepare two JPIU boards, one of which serves as backup.
	JSCC	1	One JSCC is required.
	JEOW	1	It is used to configure orderwire phone. (Optional)
	JCOM	1	One JCOM is required.
	JPBU	1	One JPBU is required.
	EMPU	1	One EMPU is required.
	JBPA	1	The NE needs a BPA and a DCU at the same time.
	JDCU	1	The NE needs a BPA and a DCU at the same time.
