The present document defines the rate adaptation functions to be used in PLMN Mobile Stations (MS)s for adapting terminal interface data rates to the Mobile Station - Base Station System (MS-BSS) interface data rates in accordance with TS 43.010.
The provision of these functions will depend on the services a particular station is designed to support.

2.2 Definitions p. 7
For the purposes of the present document, the following terms and definitions apply.
Overall data stream:
The data stream in those parts of the network where the data flow is not split into multiple channels.
Substream:
Stream of data with explicit or implicit numbering between splitter and combiner functions.
Channel:
A physical full rate channel on the radio interface (TCH/F) independent of the contents
Multislot intermediate rate:
Intermediate rate per substream in those parts of the network where the overall data stream is split into substreams.
Intermediate rate:
Intermediate rate in the overall data stream.
Substream rate:
The user rate including padding, if applicable, on one individual substream
EDGE channel:
A general term referring to channels based on 8PSK modulation; i.e. TCH/F28.8, TCH/F32.0, and TCH/F43.2.
