I am setting up a lab to test a PPP connection to 2 Cisco 2501's. My intended lab is as follows. When setting this up do I need to use from one router to CSU a MALE DTE V35 (CAB-V35MT=) and from the other router to the CSU a MALE DCE V35 (CAB-V35MC=). What would be the pin out from the cable between the CSU's RJ45 plugs. Would I simple need a role over cable? I know what the router config's should be, my question is layer 1.
