IP telephony transport
First Claim
1. A system for simultaneously transporting internet protocol voice traffic and power between an Internet Protocol telephone and an Internet Protocol voice telephony switch using twisted pair wiring comprising:
- a twisted pair broadband switch, the twisted pair broadband switch connecting on one end to an internet protocol telephone voice switch using Ethernet wiring and connecting on another end to a media converter comprising a twisted pair interface for receiving voice traffic and power from the twisted pair broadband switch through the twisted pair wiring, a twisted pair broadband chip for conditioning Ethernet traffic to be carried on a broadband interface, an Ethernet chip for storing and forwarding Ethernet packets between the twisted pair broadband chip and the external Ethernet interface, and a Field Programmable Gate Array for initializing and controlling the twisted pair broadband chip and the Ethernet chip, the media converter conditioning voice traffic between a twisted pair interface and an Ethernet interface to allow connection to an internet protocol telephone; and
,a power source connected to the twisted pair broadband switch for providing in-line power to the telephony system.

Abstract
A system for simultaneously transporting internet protocol voice traffic and power to an internet protocol telephony transport using the existing twisted pair infrastructure of a traditional phone system. The system includes a twisted pair broadband switch. The twisted pair broadband switch connects on one end to an internet protocol telephone voice switch using Ethernet wiring and connects on another end to a media converter using a twisted pair wiring on the existing twisted pair infrastructure. The media converter condition the voice traffic between a twisted pair interface and an Ethernet interface to allow connection to an internet protocol telephone. Power is simultaneously transported with the voice traffic over the same twisted pair wiring of the existing twisted pair infrastructure.
