3. Each group is assigned a probability with which Hub will allocate a bandwidth to stations belonging to this group The term allocate a bandwidth means providing at least one TDMA time slot Probability is a number from 1 to 255 meaning how many times during 255 sequential TDMA frames Hub IC will provide each station with one TDMA slot for transmission If probability is 255 such slot is provided to stations in each frame If probability is 128 such slot is provided in each other frame and if 32 in each eighth frame Table here defines bandwidth requesting parameters of stations For profiles exist Each TDMA station is always assigned one of profiles Active Coefficient for active stations Coefficient for idle stations Down Coefficient for down stations Timeout Timeout in frames to declare station idle if it doesn t request bandwidth A question may arise on why probability is needed for active stations if they request a bandwidth and already have a possibility to transmit new requests to Hub But if there is a request for bandwidth it does not mean that they will get it it depends on the network and traffic settings But if these stations do not obtain a bandwidth Hub should be aware of their requests e g owing to the fact that requests from stations may grow and then Hub will allocate a bandwidth for them Typical probabilities are 255 for active stations 32 for idle ones and 32 for down stations 8 14 Return channel Return

12. IP packets transmitted to the satellite from Hub can be received on many stations simultaneously Since different networks are routed to different stations it is logical that each SVLAN be assigned to a separate direction and this is what is usually done But it may happen so that due to the router wrong configuration or in case of mixing routers traffic into one SVLAN e g into SVLAN 0 for a better channel efficiency not all traffic received via SVLAN will be lead out from the router to LAN there will be no routes If in this case the default route on the router is set to the HUB a rooting loop may be generated the result being that channels will be instantly overloaded with circulating packets Modulator l TOMA demodulator IP screening To avoid this situation UHP 1000 router is provided with a special mechanism IP screening This mechanism works as follows each packet received from satellite gets a tag If during routing this packet tries to go back to the satellite it will be dropped Packets coming from LAN and generated by the router itself are not tagged and they have no limitations whatsoever Other settings IP screening AUTO Apply Other settings IP screening Enable IP screening Automatic IP screening is active by default for the following modes of router operations STAR station MESH station DAMA station and HUBLESS station This mechanism automatically disabled in modes SCPC HUB and HUBLESS Master av
