NEC NEAX2400 system manual Fusion Network Examples

GENERAL

Fusion Network Examples

When the NDM (master) is modified, the new data is automatically copied.

	NCN	LN	LN
	DM	DM	DM
Change...	LDM	LDM	LDM
	NDM	NDM	NDM
	(master)
Fusion Link		copy	copy
	The standard size of each memory is as follows:		DM (Data Memory): 4M Bytes
			LDM (Local Data Memory): 2M Bytes
			NDM (Network Data Memory): 2M Bytes
NCN: Network Control Node		LN: Local Node

6. Fusion Network Examples

Figure 2-9and Figure 2-10show examples of Fusion networks. When incorporating the Fusion system with the existing CCIS network, all nodes must be connected via CCIS links.

Note: To connect a CCIS network and Fusion network, use STNs and TELNs respectively.

	3xxx: CCIS for Node C
[Closed Numbering]	2xxx: CCIS for Node B		CCIS
	1xxx: self-Node
