Description  

Half-duplex 

Half-duplex communication is also called “two-way alternate communication”. It 

indicates the communication is provided in both directions, but only one direction at 

a time, that is, only one party is allowed to transmit or receive at a time.   

Full-duplex  

Full-duplex communication is also called “full-duplex synchronous communication”. 

It indicates the communication is allowed in both directions simultaneously, that is, 

both parties can transmit and receive at the same time.   

Direct Mode 

Operation 

(DMO)

DMO supports half-duplex operation and allows the terminals to communicate 

directly with each other, without using a TETRA network infrastructure. Thus 

functions that require network access, such as telephone call, will be unavailable.   

Trunked Mode 

Operation 

(TMO)

TMO supports either half-duplex or full-duplex operation and allows the terminals to 

communicate with each other via the TETRA network. Thus functions that require 

network access are available. To operate in TMO mode, the terminal must be 

granted authorization by your service provider, and must stay within the network 

coverage.
