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.
