CCLSEVT (VCLSEVT) is reported when the connection between the remote system and the MCF or communication management program has been released . The MHP can recognize that a connection has been released by receiving CCLSEVT (VCLSEVT).

The way of reporting connection release depends on the protocol supporting product. For details on the format of CCLSEVT (VCLSEVT), see the applicable OpenTP1 Protocol manual.

The figure below shows the outline of CCLSEVT (VCLSEVT).

1. Connection release is requested from the local OpenTP1 system or the remote system. In this example, the local OpenTP1 system requests connection release. Depending on the protocol supporting product, there may be no response.
2. When the connection has been released, CCLSEVT (VCLSEVT) is reported and the MHP for an MCF event is scheduled.
3. The MHP for an MCF event performs proper processing for CCLSEVT (VCLSEVT).
