3.10.9 MCF event that reports establishing a connection (COPNEVT, VOPNEVT)

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

The way of reporting connection establishment depends on the protocol supporting product. For details on the format of COPNEVT (VOPNEVT), see the applicable OpenTP1 Protocol manual.

The figure below shows the outline of COPNEVT (VOPNEVT).

  2. When a connection has been established, COPNEVT (VOPNEVT) is reported and the MHP for an MCF event is scheduled.
  3. The MHP for an MCF event performs proper processing for COPNEVT (VOPNEVT).
