Vik, you need a db-60 to db-60 DCE/DTE cable to connect the two routers back to back. A DCE/DTE cable is wired so that one end is recognized as DTE equipment and the other end is wired to be recognized as DTE equipment. You can check which end is connected to an interface by using the command show controllers serial x.
Normally the interfaces would be connected to a phone company DSx line which provides clocking. Since you will not have the clocking provided by the line you will need to set one router to provide this feature. The clocking will be established on the router that has the DCE cable end attached to it. There are lots of places that sell them for under $30.00. I have had good service from http://kg2.com/. disclaimer "not associated with them in any way, yada yada yada" just a satisfied customer. Im sure that others can provide equally good sources for the cables. Rick On Sat, 16 Mar 2002, Vik D wrote: :Hi can anyone provide a brief but simple explanation of the cabling :standards involved.
