A.4 Testing a bit-exact implementation of the PSAP receiver function

26.2693GPPConformance testingeCall data transferIn-band modem solutionTS

The set-up illustrated in Figure A.4 is used to test the bit-exact compliance of a PSAP receiver implementation.

Figure A.4: Set-up for testing bit-exact eCall modem PSAP receiver function

The set of test input PCM data files listed in Table A.4 are input into the PSAP Rx. For each test input PCM data file the following are recorded and tested:

1. The output control sequence from the PSAP Rx function is recorded with a time stamp for each control message. The sequence of recorded output control messages from PSAP Rx shall be identical to the output control sequence listed in Table A.4. The absolute value difference in time stamps of a message in the recorded and attached sequence file shall not exceed one frame.

2. The output MSD from the PSAP Rx function is evaluated. The output MSD shall be equal to the MSD indicated in the attached campaign file campaign_conformance_test.txt.

Annex B (normative):
Test set-up and sequences for testing minimum performance of eCall in-band modem receivers

This annex specifies how modem receiver implementations can be tested to determine if they conform to the minimum performance requirements.

The MSDs, codecs, and channel conditions to be used for minimum performance testing are given in the attached full campaign file official_test_configuration_file.txt.
