Also, every frame consists of 8 TS which each transports one burst. Only four consecutive burst on a given logical channel will render one block. > Apparently I don't receive a DATA_IND in every GSM frame. > If that is expected, I will need to count the number of DATA_IND frames received until I have received 104 of them. Simply checking for fn >= first_fn + 104 won't do. you will not receive 104 data indications. Every frame (if a given logical channel is active in that frame) will only transmit 1/4th of a block (l2 message). During 104 frames, on a TCH/F, you should expect: * 24 TCH/F or FACCH DATA_IND * 1 SACCH DATA_IND -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
