2.31.1 MTP3 Screening

In order to verify if a Message Signaling Unit (MSU) is permitted, the mtp screening feature compares the information of the unit attempting to pass the specific requirements of vSTP in the vSTP database. The screening functions are defined by using screening tables referred to as screen sets which contain a set of rules in which the MSU is compared. Each screen set is uniquely identified by a screen set name. MTP screening tables provide screening of MTP messages on the incoming link set.
