    161161The return value (type tlm::tlm_sync_enum)  is not used in this TLM-T implementation, and must be sytematically set to tlm::TLM_COMPLETED.

    163 In the general case, the actions executed by the interface function depend on both the phase argument, and on the transaction type (defined in the payload).
     163In the general case, the actions executed by the interface function depend on both the phase argument, and on the transaction command (defined in the payload).
    164164For sake of simplicity, the interface function proposed below does not make any distinction between transaction types.

    389389To send a VCI response packet the call-back function '''vci_cmd_received()''' uses the '''nb_transport_bw()''' method, defined by TLM2.0,  that is a member function of
    390390the class '''tlmt_simple_target_socket''', and has the same arguments as the '''nb_transport_fw()''' function.
    391 Respecting the general TLM2.0 policy, the payload argument refers to the same '''tlmt_vci_transaction''' object for both the '''nb_transport_fw()''' and '''nb_transport_bw()''' functions,
     391Respecting the general TLM2.0 policy, the payload argument refers to the same '''tlmt_vci_payload''' object for both the '''nb_transport_fw()''' and '''nb_transport_bw()''' functions,
    392392and the associated interface functions. Only two values are used for the '''response_status''' field in this TLM-T implementation:

    556556uses the '''nb_transport_bw()''' function on all its VCI target ports, with a dedicated value for the phase called '''soclib::tlmt::TLMT_INFO'''. The payload argument refers to the same
    557 '''tlmt_vci_transaction''' object as the two other phase values ('''soclib::tlmt::TLMT_CMD''' and '''soclib::tlmt::TLMT_RSP''').
     557'''tlmt_vci_payload''' object as the two other phase values ('''soclib::tlmt::TLMT_CMD''' and '''soclib::tlmt::TLMT_RSP''').
