An iDirect network is a satellite based TCP/IP network with a Star topolog in which a TimeDi!ision "#ltiple$ed %TD"& broadcast downstream channel 'rom a central h#b location is

shared b a n#mber o' remote nodes( iD) *elease +(, s#pports both iDirect SCPC downstreamcarriers and D-.S+ downstream carriers( An e$ample iDirect network is shown in 0ig#re 1(
