If the case is the second you should:

DLTs (147->162).
       text2pcap -l 147 input.txt output.pcap

+ configure ethereal to decode as TCAP that DLT.
    preferences->protocols->DLT User [ABCD]
    DLT: the one choosen
    payload: gsm_dtap
Are DTAP traces sufficiently common that it'd be useful to add a WTAP_ENCAP_GSM_DTAP - and possibly reserve a DLT_ value for it? (I don't know what binary trace formats from various GSM-tracing equipment exist, or whether they're either documented or reverse-engineerable; if any are, the ability to read them might be useful.)
