Communication on a Pilot Wire

The circuit of claim 5, wherein the first path includes a SEP 2.0 application convergence protocol stack, a IPv6 convergence layer, and a 6LowPAN convergence layer.

A pilot wire cable circuit, comprising:

• a modem coupled to a pilot wire cable in an electric vehicle charging system, the pilot wire cable coupling the electric vehicle service equipment and an electric vehicle, the modem operating to transmit both pulse width modulation (PWM) command signals and power line communication (PLC) signals to a remote device via the pilot wire cable, and
• the modem interleaving the PWM and PLC signals on the pilot wire cable so that latency requirements for the PWM signals are maintained, the modem supporting parallel protocol stacks in which PLC signals are processed in a first path and PWM signals are processed in a second path that bypasses the first path and provides the PWM signals directly to a MAC layer.
