Brief facts about trau:

Transcoder and Rate Adaptation Unit or TRAU, performs transcoding function for speech channels and RA for data channels in the GSM network. The Transcoder/Rate Adaptation Unit is the data rate conversion unit. The PSTN/ISDN switch is a switch for 64 kbit/s voice. Current technology permits to decrease the bit-rate. Since MSC is basically a PSTN/ISDN switch its bit-rate is still 64 kbit/s. That is why a rate conversion is required in between the BSC and MSC... Transcoding is the compression of speech data from 64 kbit/s to 13/12.2/6.5 kbit/s in case FR/EFR/HR speech coding. Rate adaptation without transcoding allows Tandem Free Operation, allowing the original encoded speech data to be carried in a 64 kbit/s channel. TFO offers benefits because transcoding can lead to a degradation of speech quality and requires computational resources.

Full Rate - Full Rate was the first digital speech coding standard used in the GSM digital mobile phone system. It uses linear predictive coding. The bit rate of the codec is 13 kbit/s, or 1.625 bits/audio sample.

Half Rate - Half Rate is a speech coding system for GSM, developed in the early 1990s. Since the codec, operating at 5.6 kbit/s, requires half the bandwidth of the Full Rate codec, network capacity for voice traffic is doubled, at the expense of audio quality.

Enhanced Full Rate - Enhanced Full Rate or EFR or GSM-EFR or GSM 06.60 is a speech coding standard that was developed in order to improve the quality of GSM. Enhanced Full Rate was developed by Nokia and the Université de Sherbrooke.

Adaptive Multi-Rate - The Adaptive Multi-Rate audio codec is an audio compression format optimized for speech coding. AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s.
