AT&T MERLIN LEGEND Release 3.0 System Programming Manual page 111

System Programming
In most cases, you will be at an intermediate step in the procedure you have
just completed. At that point, you can select one of the options shown on the
screen and continue programming, or you can press Exit ([ F5 ]) again. This
usually takes you back to the System Programming menu. If not, you again can
continue programming on the current screen or press Exit ([ F5 ]) again.
Idle States
A few of the programming procedures can be started only when the entire
system or some part of it, such as a trunk or an extension, is idle (not in use).
Some procedures require that the trunk or extension be idle only at the instant of
programming. Other procedures, which take longer, require the system, trunk,
or extension to be forced into remaining idle until programming is completed.
These procedures wait for the system, trunk, or extension to become idle and
then prevent the initiation of any new calls. This condition is called forced idle.
NOTE:
If a procedure requires an idle condition, perform the programming outside of
normal business hours.
If a procedure requires that the system be in an idle state and the system is
busy when you begin, you see the screen shown below.
System Busy

The screen changes to the appropriate programming screen when the system
