Day/Night System Mode
Description
Day/Night System Mode enables you to switch the System between two Day modes and a Night
mode. These modes determine incoming call handling, Toll Restriction Service (TRS) call handling,
and attendant group support.
While in a Night mode (generally used at night or any time when your office is closed), incoming
calls can ring at selected extensions (e.g., a night watchman’s extension or an extension connected to
an answering machine). Outbound calls can be restricted to certain phones. Calls can be directed to a
nighttime attendant group instead of the normal daytime attendant group.
The System provides one Night mode for night call handling. However, there are three night feature
access codes (Night, Night 1, and Night 2). These three codes may be used to provide different two-
way Voice Processing Unit messages (i.e., Night may select one message, Night 1 may select a
different message, and Night 2 may select a third message.)
Typically, the Day mode is used for normal call processing of outside calls, TRS calls, and attendant
calls. The second day mode (Day 2) may be used for alternative call handling such as during a lunch
break, etc.
There are two ways to change day/night service modes:
•
Manually
•
Automatically
The following table lists the impact on TRS, Ringing, Attendant, and Built-in Voice Processing Unit
