    4 # ber:  file(1) magic for several BER formats used in the mobile
    5 # telecommunications industry (Georg Sauthoff)
    6 
    7 # The file formats are standardized by the GSMA (GSM association).
    8 # They are specified via ASN.1 schemas and some prose. Basic encoding
    9 # rules (BER) is the used encoding. The formats are used for exchanging
   10 # call data records (CDRs) between mobile operators and associated
   11 # parties for roaming clearing purposes and fraud detection.
   12 
   13 # The magic file covers:
   14 
   15 # - TAP files (TD.57) - CDR batches and notifications
   16 # - RAP files (TD.32) - return batches and acknowledgements
   17 # - NRT files (TD.35) - CDR batches for 'near real time' processing
