When a UCD group is organized by ACD positions in multiple nodes, ACD incoming calls can not be distrib-
uted to ACD positions in the node where UCD controlling station is not accommodated when the link to be con-
nected the nodes is down.
ACD incoming calls terminated at the trunk in Node B are distributed to UCD group members in Node B.

ACD incoming calls are not distributed to any position and the caller hears the reorder tone.

Note:
Even though the FCCS link (first selected route) has a down as shown in the figure, the ACD incoming call
(to Node B) can be distributed to UCD group members of Node A, if alternate route is available. However,
this is made effective only when Back-up UCD group is provided between Node A and B (without using Back-
up UCD, the ACDP in Node A cannot control the incoming ACD call to Node B, in this case).
