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.
