3-24 DBS 576 (USA) issued October 2000 576-36-700Chapter 3. System Features Section 700 - OperationConsiderations• Daylight Saving Time can only be enabled or disabled in system programming. See Section 400:Programming for more information.Day/Night System ModeDescriptionDay/Night System Mode enables you to switch the System between two Day modes and a Nightmode. 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), incomingcalls can ring at selected extensions (e.g., a night watchman’s extension or an extension connected toan answering machine). Outbound calls can be restricted to certain phones. Calls can be directed to anighttime attendant group instead of the normal daytime attendant group.The System provides one Night mode for night call handling. However, there are three night featureaccess 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 adifferent 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 attendantcalls. The second day mode (Day 2) may be used for alternative call handling such as during a lunchbreak, etc.There are two ways to change day/night service modes:• Manually• AutomaticallyThe following table lists the impact on TRS, Ringing, Attendant, and Built-in Voice Processing Unitin the various system modes:Table 3-4.
