Roll-Over Cable is a #Twisted Pair Cable where the pin mapping is completely reverse, meaning the pin will be mapped to its total opposite order of the pin at the end of the cable. It is usually used to connect PC to Router, especially in Cisco Internetwork Operating System (IOS).

Router
Router consists of two types of interfaces: LAN interfaces and WAN interfaces. LAN interfaces could be used to connect Router to the LAN which is typically connected with an RJ-45 jack (Unshielded Twisted Pair Cable (UTP)). For connecting Router to Switch, we use a Straight-Through Cable. In the case of Router to Router, we use a Crossover Cable. For PC to Router, we will use Roll-Over Cable. LAN interface could serve Ethernet# and Fast Ethernet.
