- * $Log: l3_1TR6.c,v $
- * Revision 1.6  1996/09/25 18:34:57  keil
- * missing states in 1TR6 Statemachine added
- *
- * Revision 1.5  1996/09/23 01:53:51  fritz
- * Bugfix: discard unknown frames (non-EDSS1 and non-1TR6).
- *
- * Revision 1.4  1996/06/06 14:22:28  fritz
- * Changed level of "non-digital call..." message, since
- * with audio support, this is quite normal.
- *
- * Revision 1.3  1996/04/30 21:54:42  isdn4dev
- * SPV, callback , remove some debugging code  Karsten Keil
- *
- * Revision 1.2  1996/04/20 16:47:23  fritz
- * Changed statemachine to allow reject of an incoming call.
- * Report all incoming calls, not just those with Service = 7.
- * Misc. typos
- *
- * Revision 1.1  1996/04/13 10:25:16  fritz
