Time-Triggered Ethernet Switch Unit – TSU
The TTE Switch Unit is a modular system supporting configurations with 1 to 4 TTE switch boards.
The TSU is a rugged TTE switch system optimized for demanding Size, Weight and Power (SWaP) constraints of embedded space computer network systems and avionics for critical control applications. The TTE Switch Unit has a modular design allowing independent in-orbit replacement of the Power Supply Board, and Switch Modules. Each TTE switch board is installed in a dedicated slot and operates independently.
Each TTE Switch Board provides:
- 6x 1000 BASE-T (triple speed) + 6x 100 BASE-TX Ethernet ports, 16 Gbps total switching performance
- Safe partitioning between IEEE 802.3, rate-constrained and time-triggered Ethernet traffic (SAE AS6802)
- Switch IP for up to 4,096 virtual links, up to 8 priorities
- Fault-tolerant high-speed communication with high bandwidth (COM/MON Safety Mechanism)
