Introduction

The Affected Destination Field screen identifies the point code in the affected destination field, the concerned signaling point code of incoming MTP network management messages from another network that are allowed into the EAGLE. The gray shaded areas in Figure 7-4 shows the fields of the SS7 message that are checked by the Affected Destination Field screening function.

Network management messages contain the entry 0 in the service indicator field of the SIO. This is the last screen in the MTP portion of the gateway screening process. This nsfi for this screen has only one value, stop.

Note:

Screening of the affected destination field can also be performed without configuring an allowed affected destination field screen by specifying thedestfld=yes parameter when configuring a screen set. For more information on the screen setdestfld=yes parameter, see the sectionAutomatic Destination Field Screening.
