Cisco Router as Frame-Relay Switch cabling

Hello All,

I'm getting a small lab setup to get some practice with the use of Frame-relay as well as troubleshooting.

I have a cisco 2600 router configured to work as a frame relay switch.  The router has two WIC T-1 CSU/DSU cards installed. I also have two samller Cisco 1602 routers which also each have a WIC T-1 CSU/DSU card installed.  

My one question is the cabling to use to conenct the smaller units to the Frame-relay switch.

         <1602A>                 ?                      <2600-Frame-Swicth>                    ?               <1602B>
(S0/0) WIC CSU/DSU    -------  WIC CSU/DSU (S0/0) | WIC CSU/DSU (S0/1) --------- WIC CSU/DSU (S0/0)

Should I be using a patch ethernet cables, standard rollover cabling or some other CAT5 cableing with a different pinout?

Please advise

Thanks,

You can make cross over T1 cables with pins 12-45 so 1 goes to 4 2 goes to 5 let me see if I can find a web page http://datacomguy.tripod.com/images/t1crossover.jpg
