BSMI interprets undecoded Q.931 packets from the network, 

removing information not needed by most applications and making it 

available via an L3L4m message. If you need specific Q.931 

information not delivered with the message but that is documented 

as contained in a Q.931 packet, such as call setup messages which 

have two IEs (Information Elements) – Lower and Higher level 

compatibilities, you can get access to the entire undecoded packet via 

an L3L4mRAW_QDATA message (see the BSMI section of the Bfv 

API Reference Manual, Volume 5, for details). Raw data for Q.931 

packets that are not even processed by BSMI in the first place and 

for Q.931 packets containing user-defined ISDN messages is also 

notified via this message.
