esd.cs.ucr.eduApr 05, 1995 · • The Physical Layer defines how signals are actually transmitted. Within this specification the physical layer is not defined so as to allow transmission medium and signal level implementations to be optimized for their application. • The Transfer Layer represents the kernel of the CAN protocol. It presents
