EXECUTIVE BUSY OVERRIDE (EXTENSIONS)
Description
This feature allows a user who encounters a busy extension to dial a
code and enter the conversation. Eight hundred milliseconds before
override voice contact is established, both parties in the original con-
versation receive a warning tone (440 Hz). The tone continues for 200
ms after override is established. A 200 ms burst of the 440 Hz tone is
repeated every 6 s for the duration of the override. If the overridden
extension flashes the switchhook or goes on-hook, the overriding
extension is dropped and receives reorder tone.
Conditions
The overriding extension cannot manipulate the original connec-
l
tion in any way.
A call in which any extension has a COS that includes Option
l
Number 42 (Station Override Security) or Option Number 41
(Data Security) cannot be overridden.

l
Attendant tone cannot be overridden.
