Programming Overview

Idle States

Some programming procedures can be started only when the entire system, or
some part of the system (such as a trunk or an extension), is idle, that is, not in
use. Some procedures require that a trunk or extension be idle only at the
instant of programming. Lengthy procedures require the system, trunk, or
extension be forced into remaining idle until programming is completed. These
procedures wait for the system or trunk or extension to become idle and then
prevent the initiation of any new calls—a condition called forced idle,
If a procedure requires an idle condition, do the programming outside of normal
business hours.
If a procedure requires an idle system and the system is busy when you begin,
you see the screen shown in Figure 1-13:

When the system is no longer busy, the screen changes to the appropriate
programming screen.
System Forced Idle
When the entire system is forced idle, no calls can be made or received. The
following procedures can be done only when the entire system (all lines and
telephones) is idle:
select system mode
