38、LMN data and telematic services.Within the MS there are several different data rate adaptation functions - and a Split/Combine-function in case of amultislot data configuration - which are combined as shown in GSM 03.10 as part of the connection type.The rate adaptation functions are RA0, RA1, RA2,

39、RA1, RA1 and RA1/RA1. The RA0, RA1 and RA2 are equivalentto those functions described in CCITT recommendation V.110 11.The RA1 function is similar to RA1 but has a reduced bit rate output compatible with the coding scheme proposed fordata services on the radio interface.The RA1 function is used for

40、converting between synchronous user rates of 48 and 56 kbit/s and the rate 64 kbit/s. Theequivalent function in CCITT recommendation V.110 does not have a name.The RA1/RA1 is a relay function, used as indicated in GSM 03.10.In multislot data-configurations the overall data stream is split into paral

41、lel substreams between the Split/Combine-functions.3.1 Overview of data rates and configurationsIn Table 1, an overview of the supported transparent air-interface user rates is given. For each rate, also intermediaterates per channel between BTS and MSC, overall radio interface rates, and channel co

42、nfigurations are given. For singleslot connections the intermediate rates are per channel carrying the overall data stream, whereas for multislotconnections, the intermediate rates are per substream.In Table 2, intermediate rates within the MS, overall radio interface rates, and channel configuratio

43、ns are given for theair-interface user rates. The intermediate rates are per overall data stream.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 rat

44、es are 16 and 8 kbit/s per TCH/F,respectively.For TCH/F14.4 channel coding, the multislot intermediate rate is 16 kbit/s per TCH/F.Between the TE and the Split/Combine-function at the MS, where the overall data stream is not split, intermediate ratesof 8, 16, 32 and 64 kbit/s are applicableETSIETSI
