What do you mean?

Ethereal currently decodes M3UA messages (including, AFAIK, all the 
parameters).  If the payload is ISUP or SCCP Ethereal then decodes the 
M3UA payload as either one of those protocols.  For SCCP it will then 
(if the SSN is in the range [5-12]) decode the TCAP portion of the 
message and then possibly MAP.

If you're looking for an M3UA + SS7 protocol analyzer, Ethereal does a 
lot of that already (suggestions for improvements--or patches--are 
always welcome).  If you're looking for a decoder library to use in an 
M3UA implementation, however, Ethereal will _not_ do that.
