SCCP users (e.g., TCAP) basically must register with Ethereal for an 
SCCP SSN.  The TCAP dissector I sent you does this in these lines of code:

>         dissector_add("sccp.ssn", 6, tcap_handle); /* HLR*/
>         dissector_add("sccp.ssn", 7 , tcap_handle);     /* VLR */
>         dissector_add("sccp.ssn", 8 , tcap_handle); /* MSC */

If you want to use that TCAP dissector with a different SSN, you'd have 
to add that SSN here (or change one of those lines).  (A better design 
would be to make the TCAP dissector use configurable SSNs--something I'd 
do if I ever have a chance to look at/finish/whatever that TCAP dissector.)
