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