i had a merlin system with t1's on slot 5 and 11 using b-ch grps 80 and 79 respectively. then 1 added a third t1 on slot 3, now i can't use b-ch grp 79 and i can't delete the old channels assigned there(slot 11) previously. a check on the b-ch grp 79 will show no lines are assigned to it but the print pri info report will show that some slot 11 channels are still there. as a result, i can't make use of the b-ch grp 79 and is causing problems. pls help on how to clear the b-ch grp 79...
