3.4.2 Central Office Incoming Call (Ring Down)
Each node can specify a terminating node for Ring Down calls using the system data. In this example,
Node A and Node D specify Node C and Node E as the terminating node respectively. The terminating
node is assigned using the ASYDL command (SYS 1,  Index 640). Note that self-FPC is assigned at the
terminating node.
Note 1:When assigning the data regarding the call termination to ATT, be sure to develop the unified data at each
node.
Note 2:Terminating node cannot be assigned differently at each tenant (TN).
Note 3:When the connection routes (C_RT) are all busy, any attempted call via C.O. Line is not connected to the
ATT. As a result, the calling party is provided with the Ring Back Tone (RBT), and even when a C_RT later
becomes idle, the RBT connection is still maintained and the C.O. call does not terminate to the ATT.

3.4.3 Day/Night Change
Day/Night information is transferred from an ATTCON/DESKCON to predetermined nodes.  In this example,
Node C specifies Node A and Node B as destination nodes by assigning FPCs 1 and 2 in Indexes 704-735. Node
A and Node B specifies Node C as a terminating node for Ring Down calls from PSTN by assigning FPC 3 in
Index 640. Node E specifies Node D as a destination.
Note 1:When assigning ATTCON/DESKCON on the Fusion network, be sure to develop the unified System Data
at each node.
Note 2:Terminating node cannot be assigned differently at each tenant (TN).
Figure 3-19   Day/Night Information Transfer by ATTCON/DESKCON
When an ATTCON/DESKCON is not provided on the Fusion network, Day/Night information is effective for
node accommodating an external key box.
