Retail fueling environment utilizing powered communication over legacy cabling
First Claim
1. A system incorporated into a fuel dispenser for controlling the fuel dispenser and operatively connected to one or more backroom components via legacy cabling, the system comprising:
- a coupler communicatively coupled to the legacy cabling for receiving powered communications from the one or more backroom components over the legacy cabling during a power outage;
a broadband communications modem for communicating with the one or more backroom components, wherein the coupler provides power from the powered communications to the broadband communications modem during the power outage but is otherwise powered by a mains power source at the fuel dispenser; and
a legacy interface connected to the legacy cabling for legacy communications when the powered communications over the legacy cabling is not occurring, wherein the legacy interface is disconnected from the legacy cabling when the powered communications over the legacy cabling is occurring.

Abstract
Various systems and methods are provided for facilitating powered communications over legacy cabling. This can be implemented in a fuel dispensing environment where the fuel dispenser can include a diode coupler communicatively coupled to the legacy cabling for receiving powered communications from one or more backroom components over the legacy cabling during a power outage, and a broadband communications modem for communicating with the one or more backroom components, wherein the diode coupler provides power from the powered communications to the broadband communications modem. Relays can be used at the fuel dispenser and/or backroom components to determine whether to use the powered communications or legacy communications based on whether power is available at the components communicating over the legacy cabling. In addition, failsafe protection of legacy communication circuits is provided when powered communications are active.
