hi vanG,
I totally forgot…
For the repeated FACCH – impact is on the Outgoing HO Efficiency Rate, and possible on the RTCH Drop Rate.
Here are my recommendations, for RFACCH, to see if there is an impact or not:
EN_REP_DL_FACCH = 2: enabled for LAPDm command frames + LAPDm response frames
REP_DL_FACCH_LEGACY_SUPPORT = 1: repeated DL FACCH enabled for all AMR mobile stations
REP_DL_FACCH_THRES_AMR_FR = 8: 12,2 kbit/s
REP_DL_FACCH_THRES_AMR_HR = 5: 7,40 kbit/s
————————–
and for the RSACCH:
EN_REP_SACCH = 1: enabled
RADIOLINK_REP_DL_SACCH = 14
L_RXQUAL_DL_P_AMR_RXACCH = 3.5
L_RXQUAL_UL_P_AMR_RXACCH = 3.5
REP_DL_SACCH_THRES = 3
REP_UL_SACCH_THRES = 3
REP_DL_SACCH_WS = 10
REP_UL_SACCH_WS = 10
—————————
now, keep in mind that RxACCH will be visibly useful only if codec is changed to lower codecs (in FR, around 7kb/s, in HR around 4kb/s)
If you stay at 12.2kb/s, then the rep. xACCH will show no improvement at all !!
