- This file covers the encoding and decoding of facility messages and
- facility information elements.
-
- There will be 2 Functions as Interface:
-
- fac_enc( char **ntmsg, msg_t * msg, enum facility_type type, union facility fac, struct misdn_bchannel *bc)
- fac_dec( unsigned char *p, Q931_info_t *qi, enum facility_type *type, union facility *fac, struct misdn_bchannel *bc);
-
- Those will either read the union facility or fill it.
-
- internally, we will have deconding and encoding functions for each facility
- IE.
