Hi all
I am trying to guess the frame numbers where message supposed to be in 
the decrypted stream.
I can see "SYSTEM
INFORMATION 5/6/5ter" in the SACCH or "LAPDM U, func=UI" frames in wire 
shark but I don’t understand how to find this frame in the decoded file.
C1 177169 273861 1010000001011111010
P1 177169 273861 1010000001011111010
S1 177169 273861 0000000000000000000
C0 177170 273894 00101110101111110
P0 177170 273894 00101110101111110
S0 177170 273894 0000000000000000000
Can someone please explain how to identify the frames.
Tom
