The KAD/EBM/104 receives ARINC 664 Part 7 traffic on a dual redundant interface; redundant messages are removed before the stream is sent to a classifier which it then splits into two groups: parametric ARINC 664 Part 7 messages; and ARINC 429 over ARINC 664 Part 7. These are then parsed by type-specific parsers and made available across the Acra KAM-500 backplane. All parser slots are triple buffered; there are 256 parser slots for parametric ARINC 664 messages and 8192 slots for ARINC 429 messages.

The KAD/EBM/104 has two additional 100BASE-T ports that forward a mirror copy of all frames received after redundancy removal for transmission to packet recorders. Fragmentation of ARINC 664 Part 7 messages is not supported by the parser, but fragmented messages are forwarded by the relay output ports. It also supports redundancy removal and re-transmission for Ethernet fragmented frames.
