Yes Dara that helped, I wasn't confused, I know how to use this kind of
cables in frame-relay environment, this is very basic idea, of course we
have to use DCE and DTE side of the cable on the right place as they were
actually made for, I was just trying to use them in opposite fashion to see
what happens.
Thanks again for the help.

Frame-relay environment?
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

I think you are confused as to what David said. When configuring a
Frame Relay switch layer 1 DCE/DTE is independent of layer 2 DCE/DTE.
The "clock rate" command can only be applied on the layer 1 DCE side of
the cable. This can be determined by looking at the cable for a DTE/DCE
labeling, using the "show controllers serial X/X" command or by just
issuing the "clock rate" command on both sides. The side that accepts
the command is the layer 1 DCE.
In regards to Frame Relay layer 2 DCE is independent of the layer 1 DCE.
Commonly the layer 1 DCE end of the cable is connected to the FRS and
the layer 2 DCE is also configured on the FRS side. The configuration
of the Frame Relay DCE can be done by using the "frame-relay intf-type
dce" command. By default Frame Relay interfaces are DTE. Also as a
point of interest the Frame Relay DCE side is the side that commonly
generates LMI. I used the word commonly because although unusual you
can have a Frame Relay connection without LMI ;-)
