2.3.2 Signaling Control
The individual connection states are controlled via the ON | OFF key, via hotkeys and
via the UE.
The available hotkeys depend on the current connection state. All possible hotkeys are
described in the following.
For background information, refer to Chapter 2.2.4, "Connection States" , on page 16.
ON | OFF (key) / NB-IoT Signaling (softkey)
To turn the DL signal transmission on or off, use the ON | OFF key or right-click the
softkey. The current state is shown by the softkey. The signal transmission can be
switched off any time, independent of the current connection state. A yellow hour glass
symbol indicates that the signaling generator is turned on or off.
Remote command:
SOURce:NIOT:SIGN<i>:CELL:STATe
SOURce:NIOT:SIGN<i>:CELL:STATe:ALL?
Connection control hotkeys
Any interaction with a UE requires an NB-IoT downlink signal (cell). If the signal is
available (state ON, no hour glass), the UE can attach and connection control hotkeys
can be present in the hotkey bar.
The possible hotkeys are listed in the following table.
Hotkey Description
"Connect" Sets up an RRC connection.
The RRC state changes from "Idle" to "Connected".
"Disconnect" Releases the RRC connection.
The RRC state changes from "Connected" to "Idle".
"Detach" Send a detach request to the UE and detach the UE (independent of UE
reaction to the request).
"Send SMS" Send an SMS message to the UE.
