Extension Forced Idle 8
When an extension is forced idle, no calls can be made or received on that 
extension. The following procedures can be performed only when the extension 
being programmed is idle:
■ Assign call restrictions
■ Assign pool dial-out restrictions
■ Copy extension assignments
■ Assign lines, trunks, or pools to extensions
■ Assign labels to a personal directory
■ Use centralized telephone programming
When the extension is forced idle, the following occurs: multiline telephone 
users hear a reminder tone that indicates the telephone cannot be used; 
display telephone users see the message Wait: System Busy; single-line 
telephone users do not hear a dial tone.
Forced Idle Reminder Tone 8
The forced idle reminder tone is a high-low “door-telephone” tone 
→ 400 ms of 
667 Hz tone followed by 400 ms of 571 Hz tone. The tone is provided under the 
following circumstances:
■ At the extension, to remind the user that the system or the extension is in 
the forced idle state.
■ At the programming console or at a PC running WinSPM, to remind the 
System Manager that the system (or at least one extension) is in the forced 
idle state because of administrative activity.
Forced idle reminder tones occur every 20 seconds. You can adjust the volume 
of these tones with the volume control on the system console or PC.
