The system network is designed to operate with any C-band (INSAT and standard) or Ku-band satellite systems and comprised of the following major elements:
For communications from the Central Hub to the VSATs, the hub broadcasts a series of information packets to the remote VSAT over the outbound TDM channel.
For VSAT to VSAT traffic, the Central Hub has the capability to internally route the packets, thus providing a double hop communication link between VSATs. The Central Hub performs all the switching and routing of the TDM/TDMA channels to ensure the originating user ports are routed to the proper destinations.
Some additional protocols can be developed if required by a customer. Some of the protocols currently supported in the network are X.25, TCP/IP, SNA/SDLC, X.3/X.28 PAD, HDLC, Group III Fax and Voice.
