45、eral approach 3GPP TS 43.010 defines the PLMN connection types necessary to support the GSM PLMN data and telematic services. Within the MS there are several different data rate adaptation functions - and a Split/Combine-function in case of a multislot data configuration - which are combined as show
46、n in 3GPP TS 43.010 as part of the connection type. The rate adaptation functions are RA0, RA1, RA1/RA1”, RA1/RAA”, RA1/RAA and RA1/RA1. The RA0 is similar to the RA0 function described in ITU-T recommendation V.110 11 with the exception of the conversion of the rates 14.4 and 28,8 kbit/s. The RA1 f
47、unction is similar to RA1 described in ITU-T recommendation V.110 11 but has a reduced bit rate output compatible with the coding scheme proposed for data services on the radio interface. The RA1/RA1, RA1/RA1”, RA1/RAA” and RA1/RAA are relay functions, used as indicated in 3GPP TS 43.010. In multisl
48、ot data-configurations the overall data stream is split into parallel substreams between the Split/Combine-functions. 3.1 Overview of data rates and configurations In Table 1, an overview of the supported transparent air-interface user rates is given. For each rate, also intermediate rates per chann
49、el between BTS and MSC, overall radio interface rates, and channel configurations are given. For single slot connections the intermediate rates are per channel carrying the overall data stream, whereas for multislot connections, the intermediate rates are per substream. For single slot rates up to 4,8 kbit/s, the used intermediate rate is 8 kbit/s, and for the 9,6 kbit/s single slot rate 16 kbit/s. For TCH/F9.6 and TCH/F4.8 channel codings, the multislot intermediate rates are 16 and 8 kbit/s per TCH/F, respect
