Dave.... If there's no cable installed in Serial4/1/3, obviously I (atleast) need to broaden my level of research on why you do can accomplish that feat on 7500 series routers but not on 2500 series routers!
It's just not happening here! But hey....that's not a problem, don't mind expanding my horizons and if and when I find an answer, I 'll post some feedback here. Thanks for the info Dave.... Priscilla....my apologies! Off I go....to CCO!
