AbstractA DAMA control system for an SCPC satellite communication system includes first and second control stations which can independently perform centralized DAMA control through corresponding common signaling channels, a large number of slave stations capable of receiving data through either common signaling channel, and a satellite station. While one control station performs DAMA control, the other control station performs a backup operation. When one control station loses a control function, the other control station takes over centralized DAMA control.
