WAVECOM’s implementation of TETRA is based on TETRA Release 1 and will decode all TMO and DMO voice and data traffic in real-time, albeit with certain constraints (referring to the TETRA reference protocol stack and the appropriate ETSI standards):
|
Layer |
Constraints |
|
Layer 1
|
Ø Multiple Slot Transmission mode (MST) is not supported Ø Only downlink bursts are supported in the current decoder version |
|
Layer 2
|
Logical channels: User plane, traffic channels: Ø Circuit mode not supported Control plane, control channels: Ø All channels except Access Assignment Channel (AACH) Protocol Data Units (PDU): Ø Only downlink PDUs supported |
|
Layer 3 |
At layer 3, control plane PDUs are user selectable |
