Communication through Gateways
Gateway provides connectivity between radios operating in DMO Mode and the TETRA network, so that the DMO
radios can communicate with the TMO radios.
When the radio connects to a gateway, it plays a tone, displays the Gateway available message and shows an
appropriate icon. When the radio looses connection with the gateway, it plays a tone, displays the Gateway not
available message, and the gateway icon is blinking.
SDS Remote Control
The SDS remote control feature enables controlling a radio through Air Interface using SDS-TL bearer service. A
controlling terminal (for instance, a controlling radio or SwMI controlling terminal) sends the SDS remote control
messages with AT commands to be executed by the radio.

Controlling Terminal
The SDS remote control functionality works in both TMO and DMO and the remote control PDUs are sent using
terminal equipment (TE).
You can use the feature only after a successful authorization, which requires entering a valid remote control PIN
number.
The remote control messages can be sent to a group or individual radios.
