Type of MSU
SCCP
OtherSI
When an MSU has an si value of 5, 13, or 4 (ITU only), it is a CIC message. Messages with an si
value of 3 are SCCP messages. All other MSUs are considered OtherSI messages. The EAGLE 5 ISS
first tries to match each MSU with a full routing key and second with one of the partial keys as
numbered in ascending order in the table. Third, if no segment of the routing key matches either full
or partial routing keys, the EAGLE 5 ISS assigns the MSU a default routing key.
Support for MTP Status Functions
This feature, available only on IP cards that support the ss7ipgw and ipgwi applications, allows the
Message Transfer Part (MTP) status of point codes in the SS7 networks to be made available to
IP-connected media gateway controllers (MGCs) and IP-SCPs. This feature is similar to the MTP3
network management procedures used in an SS7 network.
This feature enables an IP device to:
Divert traffic from a secure gateway that is not able to access a point code that the mated secure
gateway can access
Audit point code status
