Conformance Test
6103 AMR AIME - AMR Layer 1& Protocol Analysis
6103 AIME AMR/CT - AMR Conformance Test Solution
• Protocol analyzer, Layer 1 tester and conformance
tester for GSM AMR terminals
• Modular and expandable from R&D use
to full Conformance Test System
• Accredited GCF and PTCRB test platform
• Simple to use script driven test environment
• Supports Half Rate, Full Rate & Enhanced
Full Rate speech
• Supports all AMR Coding Schemes
• Supports RATSCCH and DTX frames and
signalling
• Voice Quality Assessment tool
• Layer 3 Message Encoder option
The introduction of AMR (Adaptive Multi-Rate)
speech frames presents a new challenge for the
GSM mobile terminal developers. Not only must
half rate, full rate and enhanced full rate speech
frames be created, encoded and decoded, but support
must also be provided for eight new full rate
coding schemes and six new half rate coding
schemes. Additionally, the adaptive nature of AMR
must be accommodated. With each AMR speech
frame (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 the
rate 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 signaling
allows only a selection of four rates from the possible
six or eight to be in use at any one time.
These four rates are referred to as the active codec set. AMR allows
for the uplink and downlink active codec sets to be different. AMR
also introduces a new set of DTX frames, complicating the whole
DTX procedure.
Racal Instruments Wireless Solutions (RIWS) ProCLAIME range of
protocol analyzers increases with the addition of the 6103 AMR
AIME and 6103 AIME AMR/CT. Capable of emulating an AMR network
and all the complex coding schemes and protocol introduced to
support AMR.
The 6103 AMR AIME is designed to meet the early R&D challenges
such as RF, DSP and protocol stack development. To protect customer
investments in test systems, RIWS offers the ability to
upgrade to the 6103 AIME AMR/CT a fully compliant AMR conformance
tester capable of running both the AMR RF and Protocol tests
required to prove compliance against 3GPP TS51.010.
The 6103 AIME AMR/CT is listed at the GCF and the PTCRB as
Test Platform 10 and was the first test platform to support AMR
TS51.010 test cases.
Due to its ability to run both RF and Protocol tests the 6103 AIME
AMR/CT has more AMR test cases approved by either the GCF or
the PTCRB than any other AMR supported platform.
