# This unit test data file is a collection of TRAU-AMR-16k frames, to be
# presented to osmo_amrt_decode_trau_frame() in sequence by way of trau2rtp_amr
# test program.

# The following frames have been emitted by Nokia TCSM2 TRAU under these
# conditions:
#
# - PCM circuit type F;
# - TRAU channel activated in AMR mode with DTXd enabled;
# - CMR set to 0 (MR475) in the UL frame stream fed to the TRAU;
# - G.711 PCMA input was constant 0x54 (idle).
#
# Since the input was a form of silence (but not EHF) and DTXd was enabled,
# the TRAU emitted 7 speech frames (encoding the silence) followed by AMR DTX
# pattern of one Sid_Update every 8 frames.
#
# Please note that unlike FR/EFR, AMR TRAU frame format and semantics are
# exactly the same in UL and DL directions.  Therefore, frames emitted
# by a historical hardware TRAU are just as good for unit test purposes
# as those emitted by an E1 BTS - but much easier to produce in Themyscira lab.

# The following frames have been emitted by the same Nokia TCSM2 TRAU
# under these slightly different conditions:
#
# - G.711 PCMA input was constant 0xD5 (silence);
# - CMR in the UL frame stream fed to the TRAU (itt-ater-16 test program)
#   was manually stepped through all 8 modes.
#
# G.711 A-law (but not mu-law) has this quirk whereby the silence code (0xD5)
# decodes into 0x0008 in 16-bit linear PCM, rather than solid 0 - and all GSM
# speech encoders, including AMR, interpret a frame of all 0x0008 samples as
# an encoder homing frame (EHF).  TCSM2 AMR speech encoder also behaves in this
# manner, hence the DL output from the TRAU channel was nothing but endless
# DHFs.  This stream of DHFs exhibits mode switches on RIF=0 output frames
# whenever CMR input to the TRAU was changed.
#
# The following extract exhibits just two frames of each mode, a pair of
# RIF=0 and RIF=1 output.

# Note this quirk of Nokia TCSM2, visible in all of the DL outputs showcased
# above: when it emits speech frames, it sets CMR in its DL output to the same
# mode as its speech output mode (DL CMI, controlled by UL CMR) - but when it
# emits AMR DTX pattern (Sid_First, then occasional Sid_Update among No_Data
# frames), it emits CMR=7 in that DTXd output.  This behaviour is peculiar,
# and may be considered a bug: codec modes in UL and DL directions are
# independent of each other, hence there is no good reason for a TRAU to tell
# the BTS to limit its UL mode based on what the BTS told the TRAU regarding
# DL mode.  TS 48.060 even tells TRAU implementors that they should always emit
# CMR=7 in DL output when they are not forwarding frames from TFO - but Nokia
# implemented it wrong on TCSM2.  According to some docs, this bug is fixed in
# Nokia TCSM3i - but Themyscira HQ does not have that hw.
#
# When this quirk of TCSM2 is combined with CMR/CMI alternation in sequences
# of speech frames and the stream of TRAU frames is converted to RTP, the
# change in CMR will lag the change in FT by one frame.

# Test decoder behaviour when a RIF=1 frame occurs first out of reset,
# followed by RIF=0.  Mode 7 DHFs were taken from TCSM2 output above,
# but reordered for this test.
