    Problem Text
    The test is supposed to work as follows:
    SLAVE MASTER

    t_listen()
    t_connect() ----> T_CONNECT event
    ==> state is T_INCON
    t_look() loop
    t_snddis() ----> T_DISCONNECT event
    t_rcvdis() returns T_OK
    ==> state is T_IDLE


    This test sequence works perfectly for transport providers different from
    ISO class 2.
    In case of ISO cl.2 the test sequence looks a bit different:
    SLAVE MASTER

    t_listen()
    t_connect() ----> T_CONNECT event
    ==> state is T_INCON

    t_snddis() t_look() loop timed-out
    (NOT TRANSMITTED ==> test result "NO EVENT"
    BUT STORED LOCALLY)

    For ISO cl.2 the t_snddis() won't be transmitted as long as the connection
    request is still "pending" (i.e. neither confirmed nor rejected) but is
    stored locally. As a consequence, the T_DISCONNECT event does not occur
    on master side causing the t_look() loop to time-out.
    Acc. to ISO 8073, a connection request leads to state WFCC; a
    subsequent disconnect request changes the state to WBCL without further
    action.
    We think this test is simply not applicable for an ISO cl.2 transport provider.
    Test Output
    /tset/XTI.os/cots/rcvdis/T.rcvdis 5 Unresolved
    Test Description:
    If the implementation supports a connection-oriented transport service:
    When the current state of the endpoint is T_INCON, the ocnt == 1,
    and there is a disconnect indication on the transport endpoint,
    then a successful call to t_rcvdis(fd,discon) returns the cause
    of a disconnect in discon, changes the state of the endpoint to
    T_IDLE, decrements the ocnt by one, consumes the T_DISCONNECT
    event associated with this request from the transport endpoint,
    and returns (int) 0.

    Test Information:
    Unexpected event on ISO CLASS 2 endpoint
    Expected 16 (T_DISCONNECT), actual 0 (NO EVENT)

    Review Information

    Review Type TSMA Review
    Start Date null
    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    This problem is similar to that experienced in test accept 22 (See waiver
    reference TSDT4.021). It is recommended that a waiver is granted for this
    test on the grounds of a test suite deficiency.

    Review Type SA Review
    Start Date null
    Completed null
    Status Complete
    Review Resolution Test Suite Deficiency (TSD)
    Review Conclusion
    This is an agreed Test Suite Deficiency.
