Detroit (DMR -TETRA) Bridge
Radio Settings
Specific setting for bridged individual calls
It's recommended to use these settings on the TETRA radio to have better user experience on TETRA side
- PTT Call Back Timer - Disabled
(respond for initial delay on call DMR->TETRA) - Hook Method for Outgoing Simplex Individual Call - Direct
(respond only for transmitted call properties, the bridge is tolerant to this setting) - Preferred Hook Method for Incoming Simplex Individual Call - Direct
(allows TETRA radio to hook a call automatically - DMR side doesn't know about when the call hooked)
Specific setting for bridged group calls
It's recommended to use these settings on the TETRA radio to have better user experience on TETRA side
- PTT during Received Group Call - Enabled
(allows to transmit to group without waiting, suitable for busy groups)
