29.4.6 MLE Sleep Timer
The Field Value entry for the Mobile Link Entity (MLE) defines the period of time the terminal waits
between iterations of frequency list scanning.
Upon power up, or whenever the terminal is not attached to any cell and there are no known suitable
neighbour cells, the terminal begins to scan the frequencies.
After having exhausted all the lists, the terminal waits a provisioned amount of time before beginning
the process again from the first list. This time needs to be carefully balanced between the need to
save battery life and the need to find a system quickly after having lost coverage.
The range is 0 to 60 seconds, the default being 5 seconds.
29.4.7 Type 2 Reselection Enabled
This field needs to always be enabled except for terminals that are working on legacy Dimetra-P
releases.
Turn the check box on (Enable) or off (Disable) by clicking in the check box.
29.5 TXI Parameters (Transmit Inhibit)
Allows setting up parameters of TXI status messages the terminal will send to the dispatcher upon
activation/de-activation of the TXI (Transmit Inhibit) mode.
TXI mode, also called terminal RF (Radio Frequency) SA (Sensitive Area) Mode, is a special
terminal mode where uplink transmission of any type is forbidden except an Emergency call.
The TXI mode is activated by the terminal user in RF sensitive areas, (e.g. hospitals, airplanes,
etc.), where safety can be jeopardized due to terminal uplink high radiation. When no danger to
safety exists anymore (for instance if user leaves RF sensitive area), the user can de-activate TXI
mode and return back to normal operation.
Note: If an emergency call caused TXI mode de-activation, no status message will be sent about
TXI deactivation.
These are the same options available for the TXI One Touch Button option, see paragraph 14.3.5.
Both menus are linked and if a field value is changed in either menu, it will automatically be changed
at the other. It has the following options:
29.5.1 Activate
When TXI is enabled, the terminal can send a status message informing the dispatcher that it is in
TXI mode and is receive only. The status message number is manually entered into this field and is
not selectable from the Status List entries.
