Not only musthalf rate, full rate and enhanced full rate speech frames be created, encoded and decoded, but sup-port must also be provided for eight new full ratecoding schemes and six new half rate coding schemes. Additionally, the adaptive nature of AMRmust be accommodated. With each AMR speechframe (50 per second) a set of in-band control bits are sent. These allow the current coding rate to be signaled, in addition to requests for changes in therate of the remote sender.Also, it should be noted that AMR is asymmetric -uplink and downlink coding rates can be changed independently. Additionally, the in-band signalingallows only a selection of four rates from the pos-sible six or eight to be in use at any one time. These four rates are referred to as the active professional codec set. AMR allowsfor the uplink and downlink active codec sets to be different. AMRalso introduces a new set of DTX frames, complicating the whole DTX procedure.Racal Instruments Wireless Solutions (RIWS) ProCLAIME range ofprotocol analysers increases with the addition of the 6103 AMRAIME and 6103 AIME AMR/CT. Capable of emulating an AMR net-work and all the complex coding schemes and protocol introduced to support AMR.The 6103 AMR AIME is designed to meet the early R&D challengessuch as RF, DIGITAL SIGNAL PROCESSOR and protocol stack development. To protect cus-tomer investments in test systems, RIWS offers the ability to upgrade to the 6103 AIME AMR/CT a fully compliant AMR confor-mance tester capable of running both the AMR RF and Protocol testsrequired to prove compliance against 3GPP TS51.010. The 6103 AIME AMR/CT is listed at the GCF and the PTCRB asTest Platform 10 and was the first test platform to support AMRTS51.010 test cases.Due to its ability to run both RF and Protocol tests the 6103 AIMEAMR/CT has more AMR test cases approved by either the GCF or the PTCRB than any other AMR supported platform.*Illustration of customer configured system in Layer 1 & ProtocolConfiguration using 6103 AIME AMR/CT and other equipmentmanufacturers' products.
