Usage
In SS7 signaling, the Message Transfer Part (MTP) Level 2 message signal units (MSUs) contain a service
information octet (SIO). The SIO field in an MSU contains a 4-bit subservice field (SSF) followed by a 4-bit
service indicator. The indicator carried in the message‘s routing information typically identifies the structure
of the point code as a message from within a nation or as a message coming from outside the nation -
international. As well, the 4-bit SSF determines the point code structure of the messages transmitted from the
SGSN.
