Communication Through Repeaters; Communication Through Gateways - Motorola MTP830 S Product Information Manual

62 | Services and Features
Auto gateway
The radio can initiate calls on the selected talkgroup directly with another radio or through any available gateway
that is detected as present.
Repeater
The talkgroup links to a DMO repeater.
Specific gateway and repeater
The radio uses only the gateway with the specified gateway address for the talkgroup and/or a DMO repeater.
Automatic gateway and repeater
The radio uses the first available gateway for a talkgroup and/or a DMO repeater. If either specific gateway or auto
gateway mode is chosen, and a suitable gateway is found, all outgoing calls are placed through the gateway. If a
suitable gateway is not found, or a call setup through the gateway fails, the radio attempts to set up the call directly.
When operating on a gateway and/or repeater, the radio indicates the communication mode.

Communication through Repeaters

Radios that are out of range and cannot communicate directly one with another in DMO Mode can do it through the
repeater. The repeater is a radio that repeats all communication on a chosen channel, and as a result increases radios'
DMO range.
DMO
When the radio connects to a repeater, it plays a tone, displays the Repeater available message, and shows an
appropriate icon. When the radio looses connection with the repeater, it plays a tone, displays the Repeater not
available message, and the repeater icon is blinking.

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.
