2. OVERVIEW OF THE TTE-SWITCH LAB SPACE
7. 6 x 100/1000 Mbit/s Ethernet ports (1000Base-T via RJ45)
8. 6 x 100/1000 Mbit/s Ethernet ports (1000Base-X via SFP)
NOTE
The Ethernet port labeled – is not functional.

9. USB connector (provides access to the DSU/UART1 interface)
10. JTAG connector for factory testing and programming
11. IEC 60320-1 C14 type power connector and a power button. The switch has an electrical fuse which
protects the external power rail so that a failing switch does not cause the system power supply rail
to fail. Both the power connector and the power button serve as disconnect devices.
NOTE
Only connect the TTE-Switch Lab Space to a socket-outlet that features a grounding wire.
2.3 Functional Features
The TTE-Switch Lab Space is intended as a development platform for TTEthernet and provides the fol-
lowing features:
• A high-speed deterministic network
• Rate-constrained traffic (fully compliant with ARINC 664p7 [1])
• Time-triggered traffic (SAE AS6802 [6])
• Best-effort traffic (IEEE 802.3-2005 [4])
The TTE-Switch Lab Space is mains-operated and is developed as rack-mounted electronic ground sup-
port equipment (EGSE) for TTEthernet development and as a functionally-representative demonstrator of
space-grade components of TTTech Computertechnik AG’s space products (i.e. Switch Controller Space
and End System Controller Space).
Apart from the standard switch functions (including best-effort, rate-constrained and time-triggered Ether-
net), the switch also includes support for the following utilizations:
• Access to a TTEthernet End System via SpaceWire using RMAP
• The possibility to access the UART0 interface for debugging purposes
• The ability to use physical layers other than the 1000Base-T via SFP module slots
2.3.1 TTEthernet Implementation
• 8 sub-schedules
• 8 clock synchronization masters
• 4096 virtual links
• Store-and-forward switch architecture
