Section 700 - Operation Chapter 3. System Features
ICX-50-700 ICX (International) issued October 2000 37
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
night-time 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 Mail 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 (Call Barring) 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 (Call Barring), Ringing, Attendant, and Built-in Voice
Mail in the various system modes:

Manual Day/Night Mode
You can manually change the System mode to Day 1, Day 2, Night, Night 2, or Night 3 mode by
either entering the correct dial code or by pressing the appropriately programmed FF key.
When using manual mode, the System may be configured to either use MCO tenant Day/Night modes
or system-wide Day/Night mode.
