Satellite system for data transmission between telephone branch exchanges, traffic station and transmission method therefor

摘要

A management centre (37) of the DAMA type performs dynamic allocation of communication resources on demand. Communication between an outgoing switching centre (301), formulating a request for communication, connected to an outgoing traffic station (311), and an incoming switching centre (302), connected to an incoming traffic station (312) is established by use of an outgoing traffic station (311) comprising: - means (331) for routing the communication requests on frames cut up into time intervals each corresponding to a predetermined incoming traffic station (312), - means (35) for detecting the arrival of communication requests in the frames, - means (36) for transmitting, to the management centre (37), a request for allocation of resources comprising designation of the outgoing traffic station (311) and that of the incoming traffic station (312).
