<Back-up UCD for FCCS service>
Design of UCD station
Assign the ACD positions in the self-node as UCD controlling station at each node. By this programming, ACD
incoming calls terminated to the trunk in the self-node can be distributed to the UCD group member in the self-
node even when link down or the remote system down is occurred.
When there is no ACD positions in the node, the back-up UCD group may be organized by the non-ACD posi-
tion.
• Pattern 1 when a back-up UCD group is formed by ACD positions in a node.
ACD calls are distributed to the UCD group member in the self-node.
