Dynamic Line Buttons
Through class of service programming, the programmer can arrange certain idle line
buttons to serve as dynamic line buttons. This feature allows the system to temporarily
assign a line to a station that normally does not have the line assigned to it, and have that
line appear on a dynamic line button. While the call is appearing on the dynamic line
button (LED on), any normal call handling operations can be performed. Station class of
service programming allows certain buttons to be programmed as dynamic line buttons

End-To-End Signaling
End-To-End Signaling On Intercom
After an intercom call has been established with an analog telephony device that is
connected to the system through the JM008 expansion module or ATI-D analog terminal
interface device, the system can continue to send dialing signals (DTMF tones) through
the intercom path. This feature can be performed from every station in the system, and is
used by peripherals such as voice mail equipment.
End-To-End Signaling On Lines
After an outside call has been established, the system can continue to send dialing signals
(DTMF tones) through the telco network and have them received at the distant end for
inward call completion (bank by telephone, etc.). This conventional, off-hook dialing
feature can be performed from every station in the system.
Exclusive Hold
Exclusive hold prohibits a held call from being retrieved by any other station. The
exclusive hold condition also links a call on hold to the timed hold recall timeout feature.
After timeout, the system causes audible and visual signaling to occur and reverts the
exclusive hold condition to a normal line hold condition.
See also, Hold.
Exclusive Hold System-Wide Enable/Disable
This feature allows programmers to use system class of service programming to enable or
disable exclusive hold capability on a system-wide basis.
See also, Hold.
