AT&T 1987 AT&T Telephone User Manual


 
MANUAL SIGNALING
Description
Allows a user to signal another voice terminal.
The user may do this at any time, whether
on-hook or off-hook.
Multiline voice terminal users can signal another predesignated multiline voice terminal by
pressing an associated Manual Signaling (SIGNAL) button.
A single tone burst is provided
at the signaled terminal.
The signaling voice terminal also receives the tone and can use
this feature while in any call state.
No LED indication is associated with the Manual
Signaling feature.
When the Manual Signaling feature is used while the called station is ringing on another
call, no audible signal is received by either the signaling or the called voice terminal.
The duration of the single burst of signaling will always be the same, regardless of how long
SIGNAL is pressed. The signal is repeated each time the button is pressed.
Considerations
Manual Signaling allows a user to signal another voice terminal without calling the
terminal.
The meaning of the signal may be prearranged between the sending and the
receiving parties.
Only multiline terminals may be signaled.
Interactions
External Alerts: Manual Signaling will not activate external alerting devices
associated with the signaled station.
Administration Requirements

Assign Manual Signaling button.
