Service Conditions (cont’d)
10. When the Attendant's NITE key or external switch is turned ON and OFF repeatedly, the messages printed
out and the operation may not coincide, but the system message will represent the final day/night mode.
11. In the following cases, day/night mode is not changed when the external switch is turned ON, and only the
system message is printed out:
a.) When neither the ATTENDANT NIGHT TRANSFER [A-19] or TAS [T-8] is available, SYS2
Index 13 b1=1 (no check by Attendant at the time of day/night mode changeover), and the NITE
key of Attendant indicates Day.
b.) When neither ATTENDANT NIGHT TRANSFER [A-19] or TAS [T-8] is available, SYS2 Index
13 b1=0 (check by Attendant at the time of day/night mode changeover), and the NITE key of
Attendant indicates Night.
12. When day/night mode changeover is activated by jack at the time System Data is SYS1, Index 77 b0=1
(day/night mode changeover by jack available), the cause of changeover is indicated as NITE key (=1).
13. This feature is to be controlled by the Attendant Console accommodated in the terminating node for the
FCCS network.
14. Day/Night mode is changed by the destination node of the operator call assigned system data for the FCCS
network.
Note
15. The node which does not accommodate the Attendant Console controls DAY/NIGHT mode of the self-
node using the external key for the FCCS network.
16. The user can assign only one destination node from a node, even when the system is organized by more
than one tenant.
Note: The following Attendant Console Day/Night Mode Change methods are determined by system data: By the
Primary Attendant Console / By all Attendant Consoles
