LEARNING EVENT 10: EMPLOYMENT
1. In their normal employment, the AN/MSQ-114 and the AN/FSQ-124 can control a number of GMFSC
terminals. The exact number of terminals being controlled depends on the network configuration and the
mission requirement. A point-to-point configuration is used when connectivity between two low-capacity
terminals is desired. The hub-spoke configuration uses a multichannel terminal as the hub. Up to four low-
capacity terminals are used as the spokes. When at least two hub terminals are connected by communications
and each operates with up to three spoke terminals, a hybrid configuration is derived. The control terminal can
monitor and control any configuration that may be active within the control area.
2. In the networks designated for control by an AN/MSQ-114 terminal, the controller-
