2. Inter-Module Bus Backplane
The Chassis houses the Inter-Module Bus backplane which is a single, printed circuit board assembly.
The Inter-Module Bus backplane provides the electrical interconnections between modules in a
Trusted
TM
Controller Chassis. These interconnections are part of the physical layer communications
between modules.
Figure 2 shows a simplified top-level block diagram of the Inter-Module Bus backplane.

Please note that the above diagram illustrates only Trusted
TM
Interface modules. The chassis can
also accommodate a combination of Trusted
TM
IO and / or Interface Modules.
