Hi,

assuming you are talking about the dissection of DTAP messages (RR, MM, CC,
GMM, SM, ...), the entry point is the gsm_dtap dissector found in
packet-gsm_a_dtap.c file.
Then depending on the Protocol Discriminator, the dissect_dtap function
selects the right ett, hf, and arrays to be used for dissection.

Best regards,
Pascal.
