7.了解OSIAS7,AFS,CCS7,ETT00,ETT16,AS7的作用及区别
(1)OSIAS7:
TheinternalPCMhasnotbeenconnectedtoaninternalcircuitgrouptowhichthetimeslotsoftheterminalbelong.NameoftheinternalcircuitgroupoftheX.25terminalisOSIAS7.
ThecircuitgroupOSIAS7shouldcontaintheinternalPCMsandtime-slotsusedbydigitalX.25channels.ThecontentsofOSIAS7isupdatedwhentheninternalPCMisroutedwiththeWUCcommand.
(2)ASF:
