Modules
The terminal is modular in design, which helps reduce mean time to repair (MTTR). It is designed for
19-inch rack mounting and is only 2U high for standard configurations.
The five main modules housed inside the chassis are the transceiver, modem, motherboard, power
supply, and duplexer. Interface cards are fitted into the eight interface slots on the motherboard.
Modules are interconnected via several buses on the motherboard. A duplexer can be mounted inside
or outside the chassis.
The interrelationships between the components are shown below:
