An implementation may support SO 77 only for 8 kHz sample rate input/output (for example, a Basestation transcoder or a Media Gateway). An implementation may support SO 77 for both 16 kHz and 8
kHz sample rates (for example, a mobile station that supports wideband electro-acoustics).
6
Therefore, the main parameter in the decision tree is 16 kHz support in the implementation.

Depending on the implementation profile of the device under test, one of 2 possible Test Suites are to
be used to demonstrate SO 77 compliance. These 2 test suites named Test suites A and B, and the
individual tests comprising the Test suites are highlighted in Table 2.5.2-1.
