Example 7 screens the messages in a linkset for the following criteria. Figure 2-9 shows the screening order the EAGLE uses and the order that the screens must be entered into the database.

• Allow into the EAGLE messages containing the following items:
  • TUP messages containing these items:

    The OPC 017-017-017

    The DPC 050-034-049

    The following SIO information:

    • The network indicator code of 2 (nic=2)
    • The service indicator of 4 (si=4)
    • Message priority of 3 (pri=3)

    The allowed TUP message type of 100

  • ISUP messages containing these items:

    The OPC 017-017-017

    The DPC 073-200-059

    The following SIO information:

    • The network indicator code of 2 (nic=2)
    • The service indicator of 5 (si=5)
    • Message priority of 3 (pri=3)

    The allowed ISUP message type of 139

• The messages, both TUP and ISUP, that pass the gateway screening criteria are copied for the STPLAN application and are redirected for the gateway screening redirect function (specified with the actname parameter and the name of the gateway screening stop action set containing the COPY and RDCT gateway screening stop actions).
