Module TE1

Module TE1 is one of NAI's latest generation of advanced function modules. The TE1 is a single-port, tri-redundant, time sensitive networking, Ethernet communications interface module that supports three traffic classes: Time-Triggered Ethernet SAE AS6802 (TTEthernet™); ARINC 664 Part 7 and Avionics Full-Duplex Switched Ethernet (AFDX^®); or IEEE 802.3 Best-effort protocol. By supporting all three traffic classes, NAI's TE1 is the ideal solution for current users of 802.3 Ethernet, who plan to upgrade to Deterministic Ethernet ARINC 664 Part 7 (AFDX) or TTE protocols in the future. Upgrade to either ARINC 664 Part 7 (AFDX) or TTE support at any time without changing hardware.

The key feature of the TE1 module is the ability to support all three protocols as required with triple-redundancy. IEEE 802.3 Ethernet is ubiquitous and has been the standard for many years. It provides Best-effort data delivery, but does not provide any guarantee that the data was delivered or that the data was delivered in the sequence that it was sent. ARINC 664 Part 7 (AFDX) and TTE provide deterministic quality of service, which ensures that the data sent is received and in the same sequence that it was sent. The major features of ARINC 664 Part 7 (AFDX) and TTE are listed below.
