[Fusion Network Group (FUG)]

When connecting multiple Fusion networks using EX-FCCS, a Fusion Network group number is required to distinguish different Fusion Network groups. A Fusion Network Group is called as “Fusion Group (FUG)”. A maximum of 4 FUGs can be connected via EX-FCCS.

[Center Fusion Group (Center FUG)]

Identify the Center Fusion Group (Center FUG) from the FUGs in the EX-FCCS network. This is the sole node allowed to assign or delete Telephone Numbers within the self FUG and the other FUG.

1.An EX-FCCS network may consist of FUGs (connected via EX-FCCS) and NEAX2000 IVS2 sys- tems (connected via Enhanced CCIS). All FUGs must be connected to the Center FUG within a range of 1 or 2 EX-FCCs links or 1 or 2 Enhanced CCIS links from the Center FUG. In order for an end-to- end connection to be established, no more than 4 EX-FCCS or Enhanced CCIS links may be used. See Figure 8-4.
