The present document defines rate adaptation functions to be used in PLMN Base Station Systems (BSS) transcoders
for adapting radio interface data rates to the 64 kbit/s used at the A-interface in A/Gb mode and
for adapting radio interface data rates to the Iu interface in GERAN Iu mode in accordance with TS 43.010.
The number of Base Station System - Mobile-services Switching Centre (BSS - MSC) traffic channels supporting data
rate adaptation may be limited. In this case some channels may not support data rate adaptation. Those that do, shall
conform to this specification.
NOTE: This specification should be considered together with TS 44.021
to give a complete description of
PLMN rate adaptation.
