maximum of 4 FUGs can be connected in the network.

2. A center FUG should be specified from among multiple FUGs in the network. It is the sole node allowed

assigning and deleting telephone numbers within the self FUG and the others.

3. The network consists of FUGs and NEAX2000IPS systems within the range of 2 SPANs from the center

FUG and within the range of 4 SPANs from end to end.
