This document specifies that only Normal Burst can occur on an SDCCH, except for the occasional Access Burst during handover.

The good news, is that page 55 onwards, shows how the frequency hopping sequence is determined :-) F _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
