Modules talk to ADCN, modules contain APPS. LRU’s talk to IOMs to get on to ACDN

VM is a smart panel talks digitally to ACDN and is dual channel.

both A and B networks operating. Normal ops is virtual link to both networks

CKPT effect MAINTENANCE TIME LIMITED ITEM class 4 MEL item a/c effect no - after1000fh goes to class 1 – level 1

2 and 6 failed is allowed with B repair interval

CKPT effect (AVIONICS NETWORK MULTIPLE SWITCH FAULT (REDUNDANCY DEGRADED)a/c effect no- no go class 1 level 1

multiple sw fail on both networks) CLASS1 ( level 2 fault, single chime, master caution) no go

It is a class 1 level 1- a/c effect -(no go) (ECAM AVIONICS NETWORK MULTIPLE CABLE FAULT)

redundancy they share the same data. mirrored a1<->a2 a3<->a4 etc (side1<->side2)
