*Hi Saleem,
I think Mr. Brian's comment would have resolved the issue.
I had face this same issue round-about 2 years back,
The thing that comes handy herein is the command "frame-relay intf-type
dce" and applying the clock at the correct side.
And offcourse there is no need to purchase a new cable for this. :) :)
Regards,
Dara*
