3.1 Fusion Network Conditions
This section explains conditions when designing 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.

Condition 2: A maximum of four (4) Non ACD nodes can be connected as tandem nodes with 1D
channel.
 64k (1D-channel) will support 4 nodes
 128k (2D-channels) will support 5 nodes
 256k (4D-channels) will support 6 nodes
See Figure 3-10.

Condition 5: Up to eight (8) routes can be assigned as alternate routes for a connection trunk.
See Figure 3-12.
Figure 3-12   Connection Trunk Alternate Routing
Condition 6: Connection trunks and the Fusion data link must be assigned on an “associated” basis.
See Figure 3-13.

Condition 9: The maximum data link speed is “1.5 Mbps.”
Condition 10: Connection Trunks (B ch) conform to the following specifications:
 Existing external trunk cannot be used as alternate routes for connection trunks.
 Billing information on connection trunks cannot be output.
 Under the following conditions, “connection trunk seizure NG” will occur:

3.2 Centralized Billing - Fusion (Polling Method)
This section explains the conditions of Centralized Billing - Fusion, focusing on when CCIS links are
involved. To use this feature, select Center Node(s) on the Fusion network. See Figure 3-14.

3.3 Centralized Management Report-Fusion
For collection of fault information in a Fusion network, the Centralized Management Report-Fusion is
used. This feature provides automatic reporting of fault occurrence from Local Nodes to Center Node.
Figure 3-15 shows service conditions for this feature.
