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:
