    • A demand-based connection management satellite communication network includes a plurality of geographically distributed earth stations, each earth station having a frame relay protocol-based switch for interfacing message signals between terminal devices and modem unit. One of the earth stations is a hub station whose modem unit includes plural demodulators tuned to carrier frequencies transmitted from other, remote stations. Each remote station has at least one hub-programmable demodulator and/or a programmable modulator. When an originating station receives a request from a terminal device for connectivity with a terminal device at a destination station, it transmits a connectivity request message to the hub station. In response, the hub station checks a demodulator and/or modulator frequency assignment database for demodulator availability. If each originating and destination station has an available demodulator and modulator pair, the hub transmits tuning messages to the two stations, which tune their programmable modem components to each other's carrier frequency, and thereby provide bidirectional connectivity between the two remote stations.
    • 基于需求的连接管理卫星通信网络包括多个地理分布的地球站,每个地球站具有基于帧中继协议的交换机,用于在终端设备和调制解调器单元之间接口消息信号。 地球站之一是中心站,其调制解调器单元包括被调谐到从其他远程站发送的载波频率的多个解调器。 每个远程站具有至少一个集线器可编程解调器和/或可编程调制器。 当始发站从终端设备接收到与目的站的终端设备连接的请求时,它向中心站发送连接请求消息。 作为响应,中心站检查用于解调器可用性的解调器和/或调制器频率分配数据库。 如果每个起始站和目标站具有可用的解调器和调制器对,则集线器将调谐消息发送到两个站,这两个站将其可编程调制解调器组件调谐到彼此的载波频率,从而在两个远程站之间提供双向连接。
