It seems that some SYSTEM INFORMATION messages are sent on the SACCH of the SDCCH that was allocated in the IMMEDIATE ASSIGNMENT. They are on our candidate list and probably also encrypted after the CIPHER MODE COMPLETE message. reference: http://www2.informatik.hu-berlin.de/~goeller/isdn/DieGSMDmKanaele.pdf (page 23) The first column in the spreadsheet is the TDMA frame number. You can see that the SDCCH transfers one LAPDm frame in 51 frame ticks and the SACCH in 102 ticks. ___________________________________________________________ GRATIS für alle WEB.DE Nutzer: Die maxdome Movie-FLAT!
