I.3.1 Examples for speech and 3.1 kHz audio bearer services

a) Type II information (common to all applications using these bearer services):

- information transfer capability = speech or 3.1 kHz audio;

- information transfer mode = circuit;

- information transfer rate = 64kbit/s;

- user information layer 1 protocol =A/m-law.

b) Type III information for interworking with CSPDN (3.1 kHz audio applications are assumed) - Figure I.1:

- user information layer 1 protocol =rate adaption + user rate (see Note);

Note - Only those profiles conforming to CCITT standardized rate adaption are allowed when only the above information is provided.

c) Type III information for interworking with PSTN:

i) voice applications - Figure I.2:

- user information layer 1 protocol = A/m-law;

ii) voice band data applications - Figure I.3:

- user information layer 1 protocol = A/m-law.
