These parameters are reserved for backwards compatibility only. For applications conforming to this
release, these parameters should always be set to 0.

A 32-bit value containing run-time options for the operation of MTP as follows:

— Bit 0 is set to 1 to disable the MTP3 message discrimination function (allowing the signaling point to

receive all messages irrespective of the destination point code contained in the message) or 0 to
allow the discrimination function to operate normally.

— Bit 1 is set to 1 to disable sub-service field (SSF) discrimination. If this bit is set to 0, each received

MSU with an ssf value that does not match the configured ssf value for that link set is discarded.

— Bit 3 is set to 1 to cause MTP3 to generate a User Part Unavailable (UPU) message to the network on

receipt of a message containing a Service Indicator (SI) value that has not been configured. If set to
0, the message will be discarded without sending the UPU message.

— Bit 8 is set to 1 to select ANSI operation; otherwise it should be set to 0.

— Bits 9 and 20 are used to select the point codes used in the MTP routing label as defined below:

— Bit 10 is set to 1 for ANSI operation; otherwise it should be set to 0.

— Bit 11 is set to 1 for ANSI operation; otherwise it should be set to 0.

— Bit 18 is used to control MTP functionality in the event of detection of Remote Processor Outage

(RPO). If set to 1, RPO is handled in accordance with the ITU-T 1992 (and later) recommendations. If
