Day and Night Service
Office telephone systems are typically placed in Night Service
after regular hours, or whenever the last available console is left
unattended.
Calls then ring alternate answering points—either designated
extensions, or a night bell.
Extension users can dial the Trunk Answer From Any Station
(TAFAS) Code to answer incoming calls ringing the night bell.
If the last available attendant console has not processed a call
after a programmable time-out period, the system is
automatically placed in Night Service 1.
To change the service mode
• Select the appropriate mode from the list in the
Console Status area.
Note: Contact your communications department for information
about where the answer points are and when you should select
the different services.
Questions about Day and Night Service

The change from Day to Night service may effect some users
depending on their COS and COR. For example, a user might
have a COR that allows external calls when the system is in
Day service but not when in it is in Night service.
