APPENDIX C
Buses and Other Interfaces
C.1. INTERFACE TYPES.
The various Line Replaceable Unit (LRU) in the Traffic Surveillance System (TSS) interface with each other and other systems
using primarily ARINC 429 or discrete interfaces. Each bus has a unique name. The buses are primarily ARINC 429 or discrete
format. Refer to Table C-1 for a list of the possible discrete and ARINC bus names. Refer to Table C-2 through Table C-16 for lists
of the word labels on each digital bus. Interfaces to the ECU, audio systems, and test equipment are not described here.
