(1) BITE Philosophy
(a) Description
1 The JetWave™ AES consists of the Modman, KANDU, KRFU, TMA or FMA LRUs,
plus the APM.
2 The APM is a simple memory device with no software and performs no BITE by
itself. Any BITE required for the APM is performed by the Modman. The APM is not
shown in these diagrams.
3 The BITE system divides the responsibility for BITE and historical logs in a BITE
hierarchy as illustrated in Figure 7-7.
Figure 7-7. Bite Hierarchy
4 In charge of the JetWave™ system is the AES controller. This controller is in charge
of the LRUs of the JetWave™ system, and it:
• Maintains the overall state of the AES system
• Controls the initialization and operation of the system
• Generates BITE events applicable to the system level
• Records BITE events reported by a LRU and itself in an
AES historical log.
5 Each LRU has a LRU controller that:
• Maintains the state of the LRU
• Generates BITE events applicable to the LRU
• Sends relevant BITE events to the AES controll
er (for the AES controller to
make a decision on overall AES state, and for it to record in its AES historical
log).
6 The diagram that follows is a detailed description of how the AES controller, the
LRU controllers, the historical logs, and the means of access to those logs interact.
Refer to Figure 7-8.
