ABSTRACT:
A VSAT station and a VSAT communication system have a demand assign multiple access function for keeping a transmission path only for a required period of time to effectively use frequencies. The VSAT station has a transmission controller for temporarily reading and storing communication data41to be transmitted in buffer42and outputting the stored communication data as transmission data43after elapsed of a given period of time. Communication traffic monitoring circuit45monitors the stored amount of communication data in buffer42and outputs communication path selecting signal46. Transmission data switching circuit44selects a transmission circuit to transmit the transmission data. If the communication traffic between communicating stations is increased, then dedicated line49is established in another frequency band. If CSC line48is congested, then dedicated line49is established to reduce the burden on CSC line48. Thus, frequencies are effectively used and expenses for using the satellite repeater are reduced.
