4. Node
A Fusion network consists of the following types of nodes:
 Network Control Node
Network Control Node, which must be assigned on a Fusion network, manages other nodes on the network.
This node has the Centralized-MAT to collect fault information from other nodes on the network. Multiple
nodes cannot be assigned as a Network Control Node.
 Local Node
All nodes other than Network Control Node are called Local Node. Fault information...

Data Memory Configuration
5. Data Memory Configuration
Each node on a Fusion network has the following three kinds of Data Memory:
 Data Memory (DM)
 Local Data Memory (LDM)
 Network Data Memory (NDM) -  Programmable only by the NCN.
When the contents of the NDM are changed at NCN, the new data is automatically copied to the NDM of each
node. The NDM of the NCN functions as master memory. Figure 2-7 shows how a Telephone Number change
is performed in...

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

6. Fusion Network Examples
Figure 2-9 and Figure 2-10 show 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.

When incorporating the Fusion system with the CCIS network, consider the following conditions as to the available 
Telephone Number digits:
×: Available -: Not available
Note:When the network is Open Numbering, the “digits” in the table above must be the number of “Office Code
digits + Telephone Number digits”.

Tandem connections via FCCS-ACIS can be established. In Figure 2-11, STN (A) can place a tandem call via
FCCS-ACIS.

CHAPTER 3 SYSTEM CONFIGURATION
Fusion systems can be divided into the following two types:
 Fusion system with FCH
 Fusion system without FCH
Note:Fusion Call Control Handler (FCH): PA-FCHA
This chapter explains the system configuration of each Fusion system.
1. Fusion System without FCH
A sample Fusion system configuration that does not use a DTI to carry D-channel is shown below. In this con-
figuration, the Fusion link is established between nodes using...

2.1 System Configuration
A sample Fusion system configuration that uses a DTI to carry D-channel is shown below. In this configu-
ration, the Fusion link is established between nodes via the T1 link. Figure 3-2 shows a Fusion system con-
figuration with FCH.

In Figure 3-3 LANI, HUB, FCH, and DTI are shown in a fully redundant configuration. This configuration is 
available for Release 3 or later software.

3.1 Fusion Network Conditions
This section explains how to design a Fusion network. In the following diagram, a Fusion Link is printed
in a thick line while a CCIS link is printed in a dotted line.
Condition 1: The maximum number of nodes on a Fusion network is sixteen (16) nodes.
